There are few things that are more important than having healthy vision and eyesight. The Optometrists at Eye test Sydney CBD are here to help you maintain your vision. Eye test Sydney CBD have many years of experience as well as the necessary skills and knowledge needed to successfully manage your vision and eye health.
At Eye test Sydney CBD we pride ourselves in offering the latest in vision and eye care technology with superior patient service and care.
Maintaining Your Eyes with Vision Care
It is important to maintain your vision and eye health with regular eye examinations from an optometrist. Many studies suggest that children by the age of five should have their eyes checked to make sure they do not have any visual problems such as a lazy eye, strabismus, amblyopia or blindness.
As children grow into adults, it is recommended that they visit the eye doctor yearly.
Once you are in your 20’s and as you age, it is important to continue to see the optometrist and as you get older your visits should become more frequent in order to rule out eye disease such as glaucoma, cataracts, and macular degeneration.
Tips from Eye test Sydney CBD
In addition to regular visits to your eye doctor, there are other things you can do to help protect your eyes. Here are a few suggestions:
Wear sunglasses: They can block out harmful rays that can lead to cataracts, macular degeneration, and other diseases.
Eye protection: If you work in an industry with moving parts, machinery, or dangerous equipment, you should wear eye protection. Even when playing sports many people find it necessary to guard and protect their eyes. Eye protection is usually very cheap and can be found in most hardware and supply stores.
Quit smoking: Smoking can increase the development of macular degeneration, optic nerve damage and cataracts. Contact your optometrist for information on how this can affect you personally.
Stay healthy: Eating foods that are rich in vitamins and nutrients will not only help you feel better but can also help to keep your vision at its best. Eating greens is especially great for your eyes as they contain lutein. Studies show that lutein can help to reverse the symptoms and effects of macular degeneration.
If you suffer from vision problems or would like to learn more about our services and how to protect your eyes, contact our optometry office today. We can set up an appointment or a comprehensive consultation with one of our experienced optometrists.

Macular Degeneration Treatment
At we offer treatment for macular degeneration Eye test Sydney CBD. Macular degeneration is a medical condition that happens because of damage to the retina of the eye. It usually happens to older individuals over the age of 50. It can cause a loss of vision making it difficult and sometimes impossible to see the world around and recognize people and places.
Eye test Sydney CBD forms of degeneration
There are two main types of macular degeneration and both are characterized differently. The two types are:
Wet Form: The wet form of macular degeneration is when there is a growth of abnormal blood vessels underneath the macula. The blood vessels leave blood and other fluids into the retina which then causes a distorted vision. It can make strait lines appear wavy and can even cause bling spots or loss of ventral vision. The blood vessels can eventually scar which can lead to a permanent loss of vision.
Dry for: Dry form of macular degeneration is different because instead if abnormal blood vessels, there are yellow deposits in the macula. These deposits, if minimal, don’t always cause changes or damages to vision. But as they increase and grow in size, they can lead to distorted vision as well as diminished vision. It can become difficult to read and can eventually leave to central vision loss. In either case, you may need to seek macular degeneration treatments. Contact Eye test Sydney CBD of Eye test Sydney CBD today.
Various Risks to Watch For
There are many risks associated with macular degeneration including age and heredity. It can often times be passed down from parents to children. If someone in your family suffers from this, they may be at a higher risk for disease and should talk to your doctor about your individual risk, they may benefit from macular degeneration treatment. Other risk factors of macular degeneration include:
Smoking
High Blood Pressure
High cholesterol
Obesity
If you are experience unusual symptoms such as distorted lines, dark or blurry areas in your vision or white outs in your vision, or even a change in your colour perception, contact us today. We offer macular degeneration treatment Eye test Sydney CBD and can help you with your questions and concerns about macular degeneration.

Eye Exams and Vision Testing for Children
A regular eye exam is an essential part of your child's health and should begin at an early age. In fact, many children first begin vision testing at 6 months old.
Doctors stress the importance of having your child's eyes tested before they begin school because basic visual skills are essential to learning.
An eye exam can ensure that your child has the proper focusing skills and hand-eye coordination to make sure they get off to a great start!
Long-term Benefits of an Eye Exam
An eye exam not only tests for visual impairment, but also for other underlying health issues. Even if you do not feel like you need glasses, many asymptomatic conditions exist that can be identified early on with an eye exam.
If you notice any changes in the way your eyes look or if you experience any discomfort, schedule an eye exam.

Eye test Sydney CBD office visit
An office visit is a problem focused exam. Office visits are for patients who need to be treated for red eye, glaucoma, dry eye or any medical condition related to the eye. The fees will range depending on the complexity of your problem. If you have health insurance (not the same as vision insurance) then it will be billed under it.
Eye test Sydney CBD refractive and cataract evaluations
Eye test Sydney CBD co-manages with your carefully chosen ophthalmologist during your pre- and post-operative periods for refractive or laser surgeries. Surgeries can include LASIK, PRK, ICL and cataract surgeries. If you are interested in any refractive procedure, just let Eye test Sydney CBD know during your comprehensive eye exam and she will help you decide what procedure is best for you.
Eye test Sydney CBD bifocals
The most common use of bifocals is for the treatment of presbyopia in individuals aged 40 and over. Whether or not a person has needed vision correction when younger, by the early to mid-forties, the ability to accommodate or focus the eyes has diminished.
Bifocals allow the wearer to see clearly both at distance and near despite the reduced focusing ability. Bifocals may also be used to help align the eyes if a person tends to over-cross his or her eyes at near. If you are over 40 or have any difficulty performing tasks at near, ask us whether bifocals or progressive lenses could be right for you.
How can I s glare at night or at a computer?
There can be many causes for this condition. However, many times this problem can be alleviated, or even dismissed, with the use of "AR" (Anti Reflective) Lenses. First and foremost, however, annual or semi-annual eye exams are the ONLY avenue to your eye health and the ONLY resource to ascertain the correct reason or cause for any eye ailment! That being said and once any medical or physical condition is removed as a possibility of cause, then the perfect solution for glare on computer screens, or glare from night driving would be AR (Anti Reflective) Lenses.
What's the secret to getting glasses that look great on me?
We are fortunate to be staffed with fashion experts. They not only will assist you in your desire to get the "look" that is most flattering to your features and taste, but they will ensure that your new fashionable eyewear will function nicely with your needs and lifestyle as well. This is easier said than done. That is why we have a very knowledgeable staff dedicated specifically with you in mind.
How often should I get a new pair of glasses?
This is a personal concern that can address many issues. You should change your eyeglasses when you feel that your existing eyeglasses no longer are supporting your needs, lifestyle, or taste.
In any case a visit to your doctor should not be only considered when you feel it is time for new glasses. You should visit your eye doctor at least once every year, unless otherwise instructed by your eye care provider.
Are the lenses that change colours OK for sunglasses?
A popular lens in plastics are called Transitions Lenses. When they're exposed to ultraviolet light, they become darker or change to a different colour. However most brands are not as effective in a car or in any vehicle with the "blue or grey Stripe" on a windshield. Because of the ultraviolet blocking nature of the windshields, lenses will remain pretty light when you're driving. The ultimate sunglass experience can be enjoyed with "Polarized" lenses as these lenses offer the most protection and comfort to the eye so strain and fatigue can become a thing of the past.
Eye test Sydney CBD sunglasses
Do sunglasses really help to keep my eyes healthy?
We cannot stress this enough...YES!
You know how the sun's UV rays can harm your skin-wrinkles; premature aging and skin cancer are some of the dangers of unprotected sun exposure. The same rays that age and damage your skin can and will hurt your eyes as well. Strong sunlight, and artificial light from sources like welding arcs or tanning lamps can burn the surface of the eye, much like sunburn on the skin.
Reflected sunlight (from the water, for example) is particularly dangerous. There is also evidence that exposure to UV light can contribute to the development of eye diseases that commonly occur as we age, such as cataract and macular degeneration.
Visible Light
Visible light is the part of the sun's energy that you can see. It is made up of a spectrum of colours: red, orange, yellow, green, blue, and violet. The eye is not equally sensitive to all of these colours. It is most sensitive to yellows and greens which it can see the best. The eye is less sensitive to reds and blues. Different Ultraviolet Rays Ultraviolet rays have shorter wavelengths and more energy than visible light rays. They can have a harmful effect on the eyes immediately or cumulatively from regular exposure over a number of years. The industry has set standards for how much UV may be transmitted (passed) by types of sunglasses. Ultraviolet (UV) rays are strongest at high altitudes, low latitudes, and in open or reflective environments (like sand, snow, or water). They are also strongest at midday. Scientists divide UV rays into three bands according to wavelength: UVA, UVB, and UVC.
UVA-short wave
UVA rays have been shown to penetrate the under layers of the skin, causing damage and contributing to the skin's aging and cataracts. Therefore, it is certainly wise to require protection from them in sunglasses.
UVB-long wave
UVB rays, the sunburn rays, are the ones that cause the most concern. They can cause keratitis, which is similar to sunburn on the eye, and also have been linked to the development of cataracts.
UVC
UVC rays are the shortest, the most energetic, and may be the most harmful. Fortunately, they are blocked in the upper atmosphere and never reach the earth. If sunglasses protect against UVB, we can assume they protect against any possible exposure to UVC.
Why are my lenses so thick?
Your prescription, your personal measurements, and the size of your frame are the three key factors that will determine final lens thickness. If you are farsighted your lenses will be thicker at their centre, in contrast, if you are near sighted your lenses will be thicker at their edges. New innovative technology in lens designs, and materials, have allowed us to reduce overall lens thickness by as much as 60% in many cases. Our staff will guide you toward the best possible results in helping you choose the best frame-lens combination for your ocular and fashion needs.
Can the thick lenses be made thinner?
Absolutely! Newer, thinner lens materials are being developed all the time, and we pride ourselves in constantly being up-to-date with the latest developments and materials in the optical community. This, along with the proper grinding and appropriate frame selection could make your new fashion eyeglasses distinctly thinner. Ask one of our doctors or staff about the newest innovations in lenses today.
Can I use no-line bifocals with fashionably smaller frames?
Yes. Progressive lenses will allow you to use smaller frames while maintaining terrific vision at all distances. The visual channel that progresses from distance vision to near vision is wider, and more accurate for that 'Tween' vision necessary for clarity in the area too far for close, and to close for far. It is a wonderful lens for desk and computer use as well. Please note, that in a few of the especially small frames, not all frames can be a successful candidate for a progressive lens. With this in mind, our opticians will help you with a proper fit.
Can sunglasses help night vision?
If your eyes are subjected to intense glare during the day, they will "defend themselves" by trying to adapt. This natural built-in defense mechanism will persist for several hours after the glare is removed, resulting in reduced vision. Studies show that night vision can be reduced by as much as 50% by this exposure. Wearing sunglasses during the day dramatically improves night vision.
Do regular glasses protect my eyes from the sun?
Plastic lenses do not protect your eyes. You need to have UV protection from UV rays, which are not inherent in a plastic lens. You can have a UV protective coating applied to a plastic lens, but polycarbonate lenses have built-in UV protection. Glass lenses protect your eyes from harmful UVB rays but not from UVA. Some experts think UVA rays might have long-term, damaging effects to your eyes and skin.
What are all those numbers for my prescription?
An eyeglass prescription is written in a standardized format so it can be understood globally. The right eye, is generally referred to as "OD" or "R", while the left eye is generally referred to as "OS" or "L". The right eye is almost always on in a written prescription with the left directly below. Ignoring for sample sake, the right or left eye, let's look at a example below:
-2.00 -1.00 x 90. The first number (-2.00) tells us the spherical refractive diopter (a unit of measurement) needed to correct (farsightedness or near-sightedness). In this example, a minus sign in front of the number indicates a correction for near-sightedness. A plus sign would indicate a correction for farsightedness. This is generally true when you are talking about the first set of numbers.
The plus and minus signs on the second number, generally indicates what professional examined your eyes. An optometrist usually refracts in what's referred to as "Minus Cylinder, while an ophthalmologists refracts in "Plus Cylinder". For example, an optometrists script would be -2.00 -1.00 x 90, while the same prescription written by an ophthalmologists would be; -3.00 +1.00 x 180. Please note that the second number has a plus sign, and the last number (180, the Axis) has been transposed 90 degrees.
The second number (-1.00) is for astigmatism. If there is no astigmatism correction needed then you would not see the third (180) number. Sometimes you might see the following; SPH written for a cylinder correction instead of a number and nothing written for the third number. SPH stands for "Sphere" which indicates that there is no astigmatism correction needed.
The final number (180, the Axis line) is the direction of the astigmatism. Astigmatism can be measured in any direction around the clock. We use the numbers from 001 to 180 to indicate the orientation of the correction needed.
Depending on your need, there may be additional numbers in a eyeglasses prescription as well. If your prescription has a set of numbers, or a single number with a symbol such as a triangle, or the letters " BI, BO, BU, or BD that would indicate a prism correction. BI = Base In, BO = Base Out, BU = Base Up, and BD = Base Down. It is not uncommon to have different base directions for either eye.
Also, you will see "ADD" numbers for those requiring bifocals or reading glasses. The ADD number is exactly what it indicates...; an ADD, or an additional script to an otherwise already existing prescription. For example, your prescription is -2.00 for the first number. (In this example there is no astigmatism). For the "ADD " number you have a +3.00.This would indicate that by 'Adding" the +3.00 to the -2.00, your reading prescription would be +1.00 (adding a greater positive number to a lesser negative number results in a positive answer).
What is Ultraviolet (UV) and Infrared (IR) light?
The light we see with our eyes is really a very small portion of what is called the "Electromagnetic Spectrum." The Electromagnetic Spectrum includes all types of radiation - from the X-rays used at hospitals, to radio waves used for communication, and even the microwaves you cook food with.
Radiation in the Electromagnetic Spectrum is often categorized by wavelength. Short wavelength radiation is of the highest energy and can be very dangerous - Gamma, X-rays and ultraviolet are examples of short wavelength radiation. Longer wavelength radiation is of lower energy and is usually less harmful - examples include radio, microwaves and infrared. A rainbow shows the optical (visible) part of the Electromagnetic Spectrum and infrared (if you could see it) would be located just beyond the red side of the rainbow.
Ultraviolet light (UV) is an invisible light that is part of the sun's radiant spectrum. Exposure to ultraviolet light can cause the lenses of the eye to become cloudy, causing cataracts among many other conditions. Ultraviolet light causes the eye to age faster, thus can also cause macular degeneration. You can't see ultraviolet light. It affects the eye without your awareness to its being there, and the effects are cumulative. Almost everything in nature is affected by UV light, and almost everything deteriorates because of it. Not all sunglass lenses block all of the UV light, but the lens we recommend most is a polarized sunglass lens for sunglasses and polycarbonate lenses for dress wear.
Infrared (IR) is an invisible electromagnetic radiation that has a longer wavelength than visible light and is detected most often by its heating effect. Part of the discomfort you feel in your eyes after being out in the sun for a while is caused by IR light. Not all sunglass lenses block all of the UV light, but the lens we recommend most is a polarized sunglass lens for sunglasses and polycarbonate lenses for dress wear. Although infrared radiation is not visible, humans can sense it - as heat. Put your hand next to a hot oven if you want to experience infrared radiation "first-hand!
Do I need an optometrist and or an ophthalmologist?
Both are eye doctors that diagnose and treat many of the same eye conditions. The Optometric Association defines Doctors of Optometry as: primary health care professionals who examine, diagnose, treat and manage diseases and disorders of the visual system, the eye and associated structures as well as diagnose related systemic conditions. They prescribe glasses, contact lenses, low vision rehabilitation, vision therapy and medications as well as perform certain surgical procedures.
The main difference between the two, is that ophthalmologists perform surgery, where an optometrist would not, preferring to specialize in eye examinations, as well as eyeglass and contact lens related services.
Optometrists would be involved in all of the pre- and post-operative care of these patients; collecting accurate data, educating the patient, and insuring proper healing after the procedure. An ophthalmologist is more of a medical related specialist, who would need only to be involved if some kind of surgery were being considered. An optometrist can treat most any eye condition, including the use of ical or oral medications if needed. This might include the treatment of glaucoma, eye infections, allergic eye conditions and others, to name just a few.
A third "O" that often is overlooked, is the optician. An optician is not a doctor, and they cannot examine your eye under their own license. However, a highly trained optician plays an indispensable role in the most successful eye doctors' offices. An optician most often handles the optical, contact lens, and glasses side of things. Based on their vast knowledge of lenses, lens technology and frames, they manufacture eyeglasses, as well as assist in the selection of eyewear, based on the requirements of each individual patient.
Eye test Sydney CBD glaucoma
Glaucoma is the term for a diverse group of eye diseases, all of which involve progressive damage to the optic nerve. Glaucoma is usually, but not always, accompanied by high intraocular (internal) fluid pressure. Optic nerve damage produces certain characteristic defects in the individual’s peripheral (side) vision, or visual field.
Are there different types of Glaucoma?
There are three basic types: Primary, Secondary, and Congenital Glaucoma.
Primary Glaucoma is the most common type and can be divided into open angle and closed angle Glaucoma.
Open angle Glaucoma is the type seen most frequently in the United States. It is usually detected in its early stages during routine eye examinations.
Closed angle Glaucoma, also called acute Glaucoma, usually has a sudden onset. It is characterized by eye pain and blurred vision.
Secondary Glaucoma occurs as a complication of a variety of other conditions, such as injury, inflammation, vascular disease and diabetes.
Congenital Glaucoma is due to a developmental defect in the eye’s drainage mechanism.
How is Glaucoma detected?
Early detection of open angle Glaucoma is extremely important, because there are no early symptoms. Fortunately, routine eye exams are a major factor in early detection. People with a family history of Glaucoma should be checked at intervals in their 30s to establish a baseline. Initially, detection is based often on intraocular pressure readings, but also includes observation of the optic nerve as well as evaluation of optic nerve function using visual field tests.
Is surgery necessary to treat Glaucoma?
When medication and laser surgery fail to control progression of Glaucoma, a surgical procedure known as a filtering operation is recommended to create an artificial outlet for fluid from the eye, thus lowering intraocular pressure. Requiring use of an operating microscope and a local anaesthetic, this procedure is performed in the hospital. If such a procedure is not feasible or has failed, production of aqueous fluid may be reduced by freezing (cryoprobe) or laser energy directly applied to the eyeball over the area where the fluid is produced.
The most helpful advice concerning Glaucoma is to keep in mind the importance of early detection through routine eye examination, faithful use of prescribed medications, and close monitoring by an eye doctor of the optic nerve, visual fields and pressures.
Can Glaucoma cause blindness if left untreated?
Between 89,000 and 120,000 people are blind from Glaucoma yearly. It is a leading cause of blindness, accounting for between nine and 12 percent of all cases of blindness. The rate of blindness from Glaucoma is between 93 and 126 per 100,000 population over 40.
Between two million and three million s age 40 and over, or about one in every 30 people in that age group have Glaucoma. This includes at least one half of all those who have Glaucoma are unaware of it.
What are the signs and symptoms?
In the vast majority of cases, especially in early stages, there are few signs or symptoms. In the later stages of the disease, symptoms can occur that include:
loss of side vision;
an inability to adjust the eye to darkened rooms;
difficulty focusing on close work;
rainbow Coloured rings or halos around lights; and
frequent need to change eyeglass prescriptions
Can Glaucoma be cured?
Not yet. Any sight that has been destroyed cannot be restored, but medical and surgical treatment can help s the disease from progressing.
Can Glaucoma be prevented?
Not yet, but blindness from Glaucoma can be prevented through early detection and appropriate treatment.
How can I know if I am a high risk for Glaucoma?
A number of risk factors for the development of Glaucoma exist. The most important of these include high pressure inside the eye, advanced age, extreme near-sightedness, or a family history of Glaucoma.
What is the best defence against Glaucoma?
Have annual eye exams.

Eye test Sydney CBD cataract
What is a Cataract?
(Cataract) A cataract is the clouding of the crystalline lens in your eye. This opacity obstructs the passage of light resulting in a reduction of clear vision. Normally, light passes through the clear lens and is focused onto the Retina. However, the natural aging process can cause the lens to become cloudy, or milky. The cataract blocks the passage of light through the eye and causes distorted or blurred vision, glare, or difficulty seeing in poor lighting conditions.
There are three types of cataracts:
A nuclear cataract forms in the lens. Those over 65 are more prone to develop this type of cataract. More than half of all s over the age of 65 will develop a cataract.
A cortical cataract forms in the lens, then grows from the outside to the centre of the lens. Diabetics are more prone to develop this type of cataract.
A sub capsular cataract forms in the back of the lens. Those with diabetes, high hyperopia (Far-sightedness) or retinitis pigmentosa may be at a higher risk to develop this type of cataract.
What are the symptoms of a Cataract?
You may not notice a slight change in your vision, as cataract starts out very tiny, but as it grows from the size of a pin head, you may notice that your vision is becoming blurry, and you may feel as if you are looking through dirty eyeglasses. Object edges may appear to fade into one another and colours may not appear as bright as they should.
The most common symptoms of a cataract are:
Cloudy or blurry vision.
Problems with light, such as headlights that seem too bright, glare from lamps or very bright sunlight.
Colours that seem faded.
Poor night vision.
Double or multiple vision.
Frequent changes in glasses or contact lenses.
Optical aids such as eyeglasses or contact lenses are no longer effective.
How is a Cataract treated?
Cataract surgery is a selective and successful solution to restoring vision when the cataracts seriously impair your vision and affect your daily life. Cataract surgery is the most frequently performed surgery in the United States, with millions of surgeries done each year. Cataract surgery is a routine and relatively painless procedure.
Cataract surgery is generally performed on an out patient basis. You will not need to be hospitalized or put to sleep for your doctor to perform your surgery. The procedure normally takes less than 15 minutes and you can return home shortly after your procedure. Most people will enjoy improved vision by the day after surgery or within a few days following the procedure.
To begin, your surgeon will administer a light sedative which will relax your nerves and keep you comfortable during the procedure. Anaesthetic eye drops will be used to completely numb the eye. The entire procedure is performed through an incision that is smaller than 1/8 of an inch and does not require stitches to heal.
Once the cataract is removed, an intra-ocular lens (IOL) is placed where the cataract lens was removed, to restore your sight. Most patients will not require an eye patch and will not have any discomfort.
Most patients can return to their normal daily routines; including reading, driving, and exercise, the day after surgery.
What causes a Cataract?
It is not completely known why cataracts occur in all instances but studies on the cause of cataracts will soon teach us how to more successfully treat and prevent them.
The most commonly known type of cataract is age related.
Ultraviolet light is a known catalyst for the formation of cataracts, so we recommend wearing 100% UV blocking sunglasses which will lessen your exposure over time.
Other studies point to people with diabetes as a higher risk group for cataract development than those who do not suffer from diabetes.
Cigarettes, air pollution, heavy drug usage and severe alcohol consumption may also contribute to your chances of developing cataracts.
Can I be too young or old for Cataract surgery?
Any patient who can undergo a thorough eye examination can undergo surgery if the procedure is performed with ical aesthetic-drops alone.
How do I decide whether to have surgery?
Fortunately, cataracts are not life threatening so most people have plenty of time to decide about cataract surgery. However, we cannot make your decision for you, but talking with us can help in your decision. Together, we can ascertain how your cataract affects your vision and your life. If any of the below applies to you, then please contact us for a consultation.
- I need to drive, but I see too much glare from the sun or headlights.
- I do not see well enough to do my best at work.
- I do not see well enough to do the things I need to do at home.
- I have trouble trying to read, watch TV, sew, play cards, etc.
- I am afraid I will bump into something or fall.
- Because of my cataract, I am not as independent as I desire.
- My glasses do not help me see well enough.
- My eyesight interferes with many of my daily functions.
- You may also have other specific problems that we will discuss with you.
Eye test Sydney CBD cataract surgery
Most people who have a cataract recover from surgery with no problems and improved vision. This type of surgery has a success rate of 98 percent in patients with otherwise healthy eyes. If you have a cataract in both eyes, we believe it is best to wait until your first eye heals before having surgery on the second eye. If the eye that has a cataract is your only working eye, we will weigh very carefully the benefits and risks of cataract surgery.
You will be able to make the right decision for yourself if you know the facts. We are more than happy to explain anything you do not understand. There is no such thing as a "dumb" question when it comes to your health.
How soon can I drive after the surgery?
We will require that you have someone drive you home following your procedure. However, you may drive when you feel comfortable enough to drive safely, possibly the next day.
Do I have to avoid all activities post-operatively?
No. We typically demonstrate to the patients that they can bend over immediately after surgery, pick up 20-30 pounds, and shower provided they don't get water into their operative eye. We do ask that they wear an eye shield at bedtime for the first few weeks after surgery so they do not inadvertently rub the eye during sleep. Typical follow-up evaluations are scheduled at 1 day, 1 week, 3 weeks, and 6 weeks with glasses being prescribed between the 3rd and 6th week visit.
Does Cataract surgery hurt?
The treatment itself is painless. We will place a few numbing drops in your eye(s) to make you more comfortable.
What else should I know about surgery?
We will discuss in the greatest detail your options before choosing the best technique for your surgery. We will also explain how to prepare for surgery and how to take care of yourself after it is over.
Cataract surgery is outpatient. You do not need to stay overnight in a hospital. However, you will need a friend or family member to take you home. You may need someone to stay with you for a day to help you follow your doctor's instructions.
With modern cataract surgery, most patients have fast visual recovery. Some patients are even able to drive themselves to see doctor for follow-up the day after surgery. Remember that the follow-up is very important. We will thoroughly check your progress and make sure you have the care you need until your eye recovers fully.
Will I still need glasses or contact lenses?
You may need glasses or other corrective lenses after the procedure on a temporary or permanent basis. Cataract surgery will not prevent, and may unmask, the need for reading glasses
Eye test Sydney CBD dry eye
What is Dry Eye?
In medical terms,
Dry Eye is lovingly known as "KERATOCONJUNCTIVITIS SICCA".
The tear film consists of 3 layers: A superficial lipid (oily) layer which decreases evaporation, a middle aqueous layer which contributes 90% of the tear film, and a deep mucin layer which facilitates spreading of the tears over the cornea.
How do you treat Dry Eye?
Treatment for KCS involves 3 essential components:
(1) Stimulation of tear production.
Tear production is best stimulated by the ical administration of drops or ointments to the eye to the eyes. Usually 4-6 weeks (sometimes longer) is required for tear production to improve. Usually treatment must be continued for life to maintain tear production, but it is possible in some cases to reduce usage. This is especially true if KCS is detected early before severe drying is present.
(2) Control of ocular inflammation and infection through the ical application of an antibiotic-steroid preparation. Occasionally antibiotics may be given orally.
(3) Tear replacement until return of normal tear secretion.
Can Watery Eyes Be a Symptom of Dry Eye?
Yes. As odd as it sounds, many Dry Eye sufferers experience ‘wet eyes’ due to the tear glands overproducing watery or reflex tears to compensate for a lack of a balanced tear film.
Can reading & TV or computer viewing cause Dry Eye?
During reading and TV or computer viewing, the rate of eyelids blinking reduces significantly. This causes the tear film to evaporate leading to dryness of the eyes. This may happen in some people, especially more when they are tired, or have spent long hours watching TV or computers. Computer Users tend to blink much less frequently (about 7 times per minute vs. a normal rate of around 22 times/minute).
This leads to increased evaporation along with the fatigue and eye strain associated with staring at a computer monitor. Ideally, computer users should take short breaks about every 20 minutes to reduce this factor. Also, adjusting the monitor so that it is below eye level will allow the upper lid to be positioned lower and cover more of the eye’s surface, again to reduce evaporation.
What else can cause Dry Eye?
Climatic conditions is a very significant contributor to Dry Eye.
Blepharitis can often cause Dry Eye symptoms due to inflammation of the eye lid margins, which is caused by a bacterial infection (Staphylococci). This condition can compromise the quality of the tear film causing tears to evaporate more quickly. The bacteria produce waste material that can cause a mild toxic reaction leading to chronic red, irritated eyes. Click Blepharitis for treatment.
LASIK surgery temporarily disrupts the ocular surface/lacrimal gland unit. This condition usually eventually clears up.
Diseases that may be associated with Dry Eyes include Rheumatoid Arthritis, Diabetes (especially when the blood sugar is up), Asthma, Thyroid disease (lower lid does not move when blinking), Lupus, and possibly Glaucoma.
Age - Tear volume decreases as much as 60% by age 65 from that at age 18. Dry Eye Syndrome affects 75% of people over age 65.
Hormonal changes for women can cause decreased tear production brought on by pregnancy, lactation, menstruation, and post menopause.
Dust, Pollen, and Tobacco - When tear production decreases, dust and pollen stay in the eye longer and are more likely to stimulate an allergic response. In addition, anything that makes an eye more irritated, including Dry Eye, will make an eye more sensitive to environmental irritants such as tobacco smoke.
Other - Too much coffee drinking, smoking, wearing contact lenses, air-conditioning or heat.
What are the warning signs and how is it detected?
People with Dry Eye have sandy-gritty irritation or burning in their eyes. Initially people may have symptoms only after particularly long days, or when driving, or with contact lens wear, or when exposed to extremely dry environments such as that seen in airplane cabins.
Eventually symptoms become more consistent, and if someone has sandy-gritty irritation or burning that gets worse as the day goes on, and if they have had these symptoms for more than a few days, Dry Eye should be ruled out by an eye doctor.
We will review your history and examine your eyes to make sure you do not have any other problems, and determine the cause for your Dry Eyes.
Can Dry Eye syndrome come and go?
Dry Eye syndrome does not truly come and go, but in the early stages of the condition, or with mild Dry Eye, you may only have symptoms after long days, or with environmental conditions that decrease your blink rate (i.e. computer use) or under conditions that increase evaporation from your tear film (i.e. wind, dry air, etc.).
Some patients may notice discomfort only when they wear their contact lenses. Some people may develop symptoms only when they are dehydrated--just like your mouth becomes dry, your eyes can become dry in this way.
What if I don't treat Dry Eye. Can I lose sight?
If untreated, Dry Eye can progress to a more irritable, troublesome condition called chronic conjunctivitis. It can cause considerable trouble, and Dry Eye can lead to loss of sight due to corneal scarring, so delaying treatment is not recommended.
Is there treatment for corneal scarring caused by Dry Eye?
When patients experience corneal scarring from Dry Eye, sight may be restored by corneal transplants. However, the original cause of the scarring should be addressed to prevent a recurrence of vision loss. Research and development of human corneal skin grafts to repair severe corneal damage are of great interest to us.
What can I do to prevent or control Dry Eye syndrome?
Have annual eye exams.
See us immediately if you notice Dry Eye symptoms or any decline in your vision.
Eye test Sydney CBD paediatrics
Is a school vision screening just as effective as a full eye examination by a doctor?
Vision screenings at your paediatrician or school are useful to pick up gross problems, but they do not take the place of full eye exams. A study that was funded by the National Eye Institute and was published in the April 2004 issue of Ophthalmology found that 36-39% of preschool children with one of the targeted vision disorders was missed. The requirements for grade school vision screenings consist of testing the distance visual acuity. Even near vision, which is a critical component in learning, is sometimes not tested. Farsightedness can easily be missed. Many other important tests especially for the at-risk students are left out. Thus it is very important to have a full eye examination at least before kindergarten.
Eye test Sydney CBD children paediatrics
How do you test an infant or toddler that cannot talk?
We have many tests that look at their prescription, eye alignment, basic visual acuity, eye health, focusing and tracking. One test for infants involves two cards. There are black and white stripes on one card and only a gray Colour on the other. Babies tend to look at the more interesting target (the stripes) and will do so if they can see them. The size of the stripe-pattern is varied to help determine how well they can see with each eye.
Another example is a test for a two year old. We use the Lea chart, which has simple pictures of a house, heart, square and circle. When they are presented, the child points to a card on his or her lap that matches the shape they see.
My child is struggling in school but his last eye doctor said his eyes are fine. Is there anything that could have been missed?
Unfortunately all examinations are not created equal. Most exams include eye clarity, eye health and gross eye alignment. Other tests that are equally important will look at fine eye alignment, depth perception, Colour vision, eye tracking and focusing. These additional tests can help determine if vision is a component in a child’s learning struggles. If these tests are not performed, visual problems can be overlooked leading to frustration for the child and the teacher.
My child can see airplanes and street signs that I can't see. Does he still need an examination?
Yes! This shows that the child can see well at a distance out of at least one eye. The other eye may be very blurred and the child will not complain because they are unaware. Children can have double or blurred vision with reading and not complain because it has always been that way. They believe that everyone sees the way they do and that their vision is normal, even when it is not.
Eye test Sydney CBD Lasik
Am I a good candidate for laser vision correction?
By having a consultation and eye examination at our office, our doctor will be able to determine if you are a good candidate for laser vision correction. Patients who are at least 18 years of age, have healthy eyes that are free from retinal problems, corneal scars, and any eye diseases are generally suitable.
Many patients who are near sighted, farsighted or have astigmatism are potential candidates. We will also discuss your lifestyle needs to help you decide if LASIK is the best alternative for you.
How long does the surgery take?
The entire procedure takes approximately 15 minutes for both eyes, and about 5 to 7 minutes per eye.
After LASIK how soon can I return to work?
Most patients are back to work the day after surgery, depending on the work environment. We do ask that you try to relax for a couple of days if possible.
Will I need reading glasses after my surgery?
Generally, patients under the age of 40 still read well without the use of glasses following the surgery. Patients over the age of 40 may need reading glasses for small print. Presbyopia is a term that refers to the natural weakening of the muscles that occurs in our early to mid 40s, causing us to need reading glasses. LASIK does not correct or prevent presbyopia. Should you fall into this age category, we will be happy to discuss monovision with you at your consultation. This is an option that allows many patients the convenience of near and distance vision without the use of reading glasses.
Are follow-up visits included?
Our patients are always seen the day following the procedure and then again at one week, one month, three months, and six months following surgery. On occasion, patients require being seen more often. We offer our services twenty-four hours-a-day should you have any questions or concerns.
How soon can I drive after the surgery?
We will require that you have someone drive you home following your procedure. However, you may drive when you feel comfortable enough to drive safely, possibly the next day.
What type of anesthesia is used during the surgery?
ical numbing eye drops are used during your procedure. Sometimes an oral medication is offered to help you relax. We do not use any needles during your surgery.
Does LASIK hurt?
The treatment itself is painless. We will place a few numbing drops in your eye(s) to make you more comfortable. You will feel pressure on and around the eye during the procedure. Some patients may experience a feeling of “something in the eye” for a day or two after treatment.
Will I be able to have both eyes treated at the same time?
Surgery can be performed on both eyes on the same day if your doctor feels you are a good candidate. Should you wish to have one eye done at a time, the doctor will discuss this with you and we can accommodate this as well.
Will I still need glasses or contact lenses?
The goal of refractive surgery is to reduce your dependence on glasses or contact lenses. An occasional patient may need to wear a thin pair of prescription glasses for driving at night.

Eye test Sydney CBD IntraLase Method
The IntraLase Method is a 100% blade-free technique used to perform the critical first step in the LASIK procedure: creating the corneal flap. The creation of the corneal flap prepares the eye for the second step of the LASIK procedure, where an excimer laser is used on the inner cornea to correct vision.
How does the IntraLase Method work?
The IntraLase Method uses tiny, rapid pulses of laser light to create your corneal flap—instead of using a metal blade—during the first step of LASIK. Each pulse of light passes through the layers of your cornea and forms a microscopic bubble at a specific depth and position within your eye that is determined by the doctor. The IntraLase® laser moves back and forth across your eye, creating a uniform layer of bubbles just beneath your corneal surface.
Just prior to applying laser vision correction, the doctor creates your corneal flap by gently separating the tissue where these bubbles have formed. The corneal flap is then folded back so the doctor can perform the second step of your LASIK treatment.
What is the difference between a corneal flap created with
the IntraLase Method and one created with a microkeratome?
The microkeratome is a hand-held instrument, which contains a steel blade that moves back and forth and creates a cut as it travels across the cornea. A microkeratome is only capable of making a single, one-dimensional cut across the cornea. As it cuts, the blade oscillates back and forth, which can leave an irregular surface after the flap is lifted. This can affect the quality of your poserative vision.
Because of the unique way in which the IntraLase Method creates a precisely positioned layer of bubbles just beneath the surface of your eye, it creates a smooth even surface after your flap is lifted. With the IntraLase Method, a blade never touches your eye..
How is the IntraLase Method different from Epi-LASIK
or photo-refractive keratectomy (PRK)?
These procedures differ from one another in the way they prepare the surface of the cornea for the second step of LASIK. Epi-LASIK uses an epikeratome—a blunt separator—to make a superficial flap. Similarly, photo-refractive keratectomy (PRK) is performed by gently scraping the surface layer of the cornea, which may lead to corneal scarring. Both the Epi-LASIK and PRK procedures can be painful and require more poserative medication. In addition, healing times may be longer than with procedures performed with the IntraLase Method.
Are there other benefits to using the IntraLase Method?
There are several benefits to using the IntraLase Method:
Better vision. More patients in clinical trials achieved vision that was 20/20 or better when their LASIK procedure was performed with the IntraLase Method.(1) And patients report better quality of vision overall, particularly in terms of their ability to see well in low light such as at dusk or at night.
Ability to tailor the procedure to your eye. The IntraLase Method gives your doctor the ability to tailor the dimensions of your corneal flap based on what’s best for your eye. Everything from the diameter of your flap to the angle of its edges can be precisely determined. This is important because everyone’s eyes are shaped a little differently. Having a corneal flap that’s individualized to the patient contributes to excellent poserative outcomes. In addition, a corneal flap created with the IntraLase Method also “locks” back into position after the LASIK procedure is performed.
Is the IntraLase Method painful?
Prior to creating the flap, the doctor applies drops to numb the eye, and then applies a special ring and an instrument that gently flattens your cornea in preparation for the IntraLase Method. This part of the process is not painful—patients report feeling only slight pressure.
Is the IntraLase Method safe?
More than 600,000 procedures have been performed safely and effectively using the IntraLase Method.
How long does it take to create a flap using the IntraLase Method?
The creation of the flap itself takes only about 15-30 seconds per eye. Including preparation time, the entire LASIK procedure takes about 10 minutes.
What’s the reaction of patients who have experienced the IntraLase Method?
In a clinical survey of LASIK patients who had their corneal flaps created using a microkeratome in one eye and the IntraLase Method in the other, the vision in the IntraLase-treated eye was preferred 3-to-1 (among those who stated a preference).
Is the IntraLase Method right for me?
If you are looking for a 100% blade-free LASIK experience that virtually eliminates almost all the most severe, sight-threatening complications, the answer is yes.
LASEK is an abbreviation for Laser Assisted Subepithelial Keratectomy. LASEK is a hybrid of FDA approved PRK (Photorefractive Keratectomy) and FDA approved LASIK (Laser Assisted In Situ Keratomileusis). In this procedure, the surface of the cornea is peeled back, the laser is applied, and the surface layer is then replaced into position.
Who is a candidate for LASEK?
Patients whose corneas are too thin for LASIK
Athletes who may have a possibility for eye trauma
Patients who may have a physically active lifestyle.
Patients with certain corneal diseases
Patients with a certain degree of dry eyes
Patients concerned about a corneal flap
Patients who had previous eye surgery, such as RK or PRK
What is the difference between LASEK and LASIK and PRK?
LASEK takes the best of both PRK and LASIK. As in PRK, there is no microkeratome used during the LASEK procedure and the surface cells are replaced, like LASIK, for quicker visual recovery. However since only the epithelial cells (the outer most layer of cornea) are used in making the LASEK flap, there is no permanent corneal flap.
Will I need reading glasses after my surgery?
Generally, patients under the age of 40 still read well without the use of glasses following the surgery. Patients over the age of 40 may need reading glasses for small print. Presbyopia is a term that refers to the natural weakening of the muscles that occurs in our early to mid 40s, causing us to need reading glasses. LASIK does not correct or prevent presbyopia. Should you fall into this age category, we will be happy to discuss monovision with you at your consultation. This is an option that allows many patients the convenience of near and distance vision without the use of reading glasses.
When can I return to sporting activities or my physically active lifestyle?
Once your vision allows, you can resume all activities. You should however, avoid intense or direct strong sunlight and dirty or dusty environments for as long as possible after treatment.
How soon can I drive after LASEK?
We will require that you have someone drive you home following your procedure. However, you may drive when you feel comfortable enough to drive safely, possibly the next day.
Do I have to avoid all activities post-operatively?
No. We typically demonstrate to the patients that they can bend over immediately after surgery, pick up 20-30 pounds, and shower, provided they don't get water into their operative eye. We do ask that they wear an eye shield at bedtime for the first few weeks after surgery so they do not inadvertently rub the eye during sleep. Typical follow-up evaluations are scheduled at 1 day, 1 week, 3 weeks, and 6 weeks, with glasses being prescribed between the 3rd and 6th week visit.
Why can't I wear my contact lens wear before my preoperative exam?
Contact lenses can change the shape of your cornea similar to how a watchband can make an imprint on your wrist. If you have your eyes examined too soon after removing your contact lenses, several of the eye tests could give inaccurate results and negatively influence your surgical outcome. Discontinue wearing soft contact lenses according to the doctor's recommendation prior to the preoperative measurements and surgery. Rigid gas permeable (RGP) contact lens wearers may require a more protracted amount of time out of lens wear. Our Doctor will advise you if your corneas have not returned to their natural shape after removing your contact lenses.
Will I still need glasses or contact lenses?
You may need glasses or other corrective lenses after the procedure on a temporary or permanent basis.
What if I had a previous corneal transplant or radial keratotomy?
Research has shown that LASEK can be successfully performed after a corneal transplant or previous radial keratotomy (RK) refractive surgery. However, the decision depends on many factors. See us for a pre-operative consultation and exam to see if you are a good candidate.

Eye test Sydney CBD Types of Contact Lenses
We often are one of the first to receive the latest in Contact Lenses!
We also offer only the best in contact lens technology to provide
you with optimal vision, comfort and health
We have contacts available to target specific eye problems like dry eyes, astigmatism, difficulty reading, and eye diseases like keratoconus. We are focused on taking the time to give you the best comfort and vision, not just adequate comfort and vision. Contact lenses are constantly being improved for more comfort and better vision.
What are the different types of Contact Lenses?
Soft Contact Lenses
Soft contact lenses are made of soft, flexible plastics that allow oxygen to pass through to the cornea. Soft contact lenses may be easier to adjust to and are more comfortable than rigid gas permeable lenses. Newer soft lens materials include silicone-hydrogels to provide more oxygen to your eye while you wear your lenses.
Rigid Gas Permeable (RGP) Contact Lenses
Rigid gas permeable contact lenses (RGPs) are more durable and resistant to deposit build-up. They tend to be less expensive over the life of the lens since they last longer than soft contact lenses. They are easier to handle and less likely to tear. However, they are not as comfortable initially as soft contacts and it may take a few weeks to get used to wearing RGPs, compared to several days for soft contacts.
Continuous Wear Contact Lenses
Continuous wear contact lenses are available for overnight or continuous wear ranging from one to six nights or up to 30 days. Continuous wear contact lenses are usually soft contact lenses. They are made of flexible plastics that allow oxygen to pass through to the cornea. There are also a very few rigid gas permeable lenses that are designed and approved for overnight wear. Length of continuous wear depends on lens type and your eye care professional's evaluation of your tolerance for overnight wear. It is important for the eyes to have a rest without lenses for at least one night following each scheduled removal.
Disposable (Replacement Schedule) Contact Lenses
The majority of soft contact lens wearers are prescribed some type of frequent replacement schedule. "Disposable," as defined by the FDA, means used once and discarded. With a true daily wear disposable schedule, a brand new pair of lenses is used each day. Some soft contact lenses are referred to as "disposable" by contact lens sellers, but actually, they are for frequent/planned replacement. With extended wear lenses, the lenses may be worn continuously for the prescribed wearing period (for example, 7 days to 30 days) and then thrown away. When you remove your lenses, make sure to clean and disinfect them properly before reinserting.
Hybrid Contact Lenses
The hybrid contact lens combines a rigid gas permeable centre and a soft lens skirt into one unique "hybrid" lens. The rigid centre corrects farsightedness, near-sightedness and astigmatism and delivers clear, high definition vision, even at night. The soft skirt surrounding the centre provides the all-day comfort of a soft lens.
Orthokeratology (Ortho-K)
Orthokeratology, or Ortho-K, is a lens fitting procedure that uses specially designed rigid gas permeable (RGP) contact lenses to change the curvature of the cornea to temporarily improve the eye's ability to focus on objects. This procedure is primarily used for the correction of myopia (near-sightedness).
Overnight Ortho-K lenses are the most common type of Ortho-K. There are some Ortho-K lenses that are prescribed only for daytime wear. Overnight Ortho-K lenses are commonly prescribed to be worn while sleeping for at least eight hours each night. They are removed upon awakening and not worn during the day. Some people can go all day without their glasses or contact lenses. Others will find that their vision correction will wear off during the day.
The vision correction effect is temporary. If Ortho-K is discontinued, the corneas will return to their original curvature and the eye to its original amount of near sightedness. Ortho-K lenses must continue to be worn every night or on some other prescribed maintenance schedule in order to maintain the treatment effect. Your eye care professional will determine the best maintenance schedule for you.
Decorative (Plano) Contact Lenses
Some contact lenses do not correct vision and are intended solely to change the appearance of the eye. These are sometimes called plano, zero-powered or non-corrective lenses. For example, they can temporarily change a brown-eyed person's eye Colour to blue, or make a person's eyes look weird by portraying Halloween themes. Even though these decorative lenses don't correct vision, they're regulated by the FDA, just like corrective contact lenses.
Scleral Contact Lenses
Scleral lenses are larger lenses made of gas permeable material used to correct vision in a number of conditions such as keratoconus, post-refractive surgery corneal issues, ocular surface disease, dry eye, and even normal refractive errors.
Prosthetic Contact Lenses
Prosthetic lenses are used to achieve an improved cosmetic appearance when an eye has a misshaped pupil. If two eyes appear different due to a pupil irregularity, prosthetic lenses can be designed to match the iris of the other eye.

Why do some frames cause a reaction on my skin?
If metal frames cause a reaction, nickel is the culprit. Most metal frames are made of a nickel alloy. Other metals used include aluminium, stainless steel, titanium, zinc, copper, beryllium, gold and silver. Stainless, titanium, gold and silver are usually hypoallergenic.
Some people can also be allergic to the nose pads on metal frames. Most are made of silicone or acetate, but they can also be made out of polyvinyl chloride (PVC), nickel, titanium or rubber. Silicone is tricky. Certain silicones are hypoallergenic (such as medical silicone), but others can trigger allergic reactions. Both PVC and titanium are usually hypoallergenic. Most plastic eyeglass frames are made of zyl (also called zylonite, acetate and cellulose acetate) or propionate. Other materials used in plastic frames include: polyamide, nylon, polycarbonate, carbon and Optyl (a brand of epoxy resin). Propionate, polyamide, nylon and Optyl frames are all considered hypoallergenic.
I see fine, why do I need to see an Eye Doctor?
Regular eye exams are the only way to catch "silent" diseases such as diabetes, glaucoma and other conditions in their early stages, when they're more easily managed or treated. Many conditions can be discovered in a carefully planned eye exam. Those who consider mass-produced, over the counter reading glasses are truly doing themselves a disservice, both financially and medically.
One-size-fits-all reading glasses not only do not work well for most people who have a different prescription in each eye, and/or astigmatism, or whose lens and frame parameters are not measured correctly, they bypass the opportunity to have their eyes checked for early detection of many manageable diseases or conditions. For those insisting on selecting glasses not measured specifically for their eyes, headaches and eye fatigue are common symptoms.

How do I know if I need bifocals?
The most common use of bifocals is for the treatment of presbyopia in individuals aged 40 and over. Whether or not a person has needed vision correction when younger, by the early to mid-forties, the ability to accommodate or focus the eyes has diminished.
Bifocals allow the wearer to see clearly both at distance and near despite the reduced focusing ability. Bifocals may also be used to help align the eyes if a person tends to over-cross his or her eyes at near. If you are over 40 or have any difficulty performing tasks at near, ask us whether bifocals or progressive lenses could be right for you.
How can I s glare at night or at a computer?
There can be many causes for this condition. However, many times this problem can be alleviated, or even dismissed, with the use of "AR" (Anti Reflective) Lenses. First and foremost, however, annual or semi annual eye exams are the ONLY avenue to your eye health and the ONLY resource to ascertain the correct reason or cause for any eye ailment! That being said and once any medical or physical condition is removed as a possibility of cause, then the perfect solution for glare on computer screens, or glare from night driving would be AR (Anti Reflective) Lenses.
What's the secret to getting glasses that look great on me?
We are fortunate to be staffed with fashion experts. They not only will assist you in your desire to get the "look" that is most flattering to your features and taste, but they will ensure that your new fashionable eyewear will function nicely with your needs and lifestyle as well. This is easier said than done. That is why we have a very knowledgeable staff dedicated specifically with you in mind.
How often should I get a new pair of glasses?
This is a personal concern that can address many issues. You should change your eyeglasses when you feel that your existing eyeglasses no longer are supporting your needs, lifestyle, or taste.
In any case a visit to your doctor should not be only considered when you feel it is time for new glasses. You should visit your eye doctor at least once every year, unless otherwise instructed by your eye care provider.
Are the lenses that change colours OK for sunglasses?
A popular lens in plastics are called Transitions Lenses. When they're exposed to ultraviolet light, they become darker or change to a different Colour. However most brands are not as effective in a car or in any vehicle with the "blue or gray Stripe" on a windshield. Because of the ultraviolet blocking nature of the windshields, lenses will remain pretty light when you're driving. The ultimate sunglass experience can be enjoyed with "Polarized" lenses as these lenses offer the most protection and comfort to the eye so strain and fatigue can become a thing of the past.
Eye test Sydney CBD sunglasses really help to keep my eyes healthy?
We cannot stress this enough...YES!
You know how the sun's UV rays can harm your skin-wrinkles; premature aging and skin cancer are some of the dangers of unprotected sun exposure. The same rays that age and damage your skin can and will hurt your eyes as well. Strong sunlight, and artificial light from sources like welding arcs or tanning lamps can burn the surface of the eye, much like sunburn on the skin.
Reflected sunlight (from the water, for example) is particularly dangerous. There is also evidence that exposure to UV light can contribute to the development of eye diseases that commonly occur as we age, such as cataract and macular degeneration.
Visible Light
Visible light is the part of the sun's energy that you can see. It is made up of a spectrum of colours: red, orange, yellow, green, blue, and violet. The eye is not equally sensitive to all of these colours. It is most sensitive to yellows and greens which it can see the best. The eye is less sensitive to reds and blues. Different Ultraviolet Rays Ultraviolet rays have shorter wavelengths and more energy than visible light rays. They can have a harmful effect on the eyes immediately or cumulatively from regular exposure over a number of years. The industry has set standards for how much UV may be transmitted (passed) by types of sunglasses. Ultraviolet (UV) rays are strongest at high altitudes, low latitudes, and in open or reflective environments (like sand, snow, or water). They are also strongest at midday. Scientists divide UV rays into three bands according to wavelength: UVA, UVB, and UVC.
UVA-short wave
UVA rays have been shown to penetrate the under layers of the skin, causing damage and contributing to the skin's aging and cataracts. Therefore, it is certainly wise to require protection from them in sunglasses.
UVB-long wave
UVB rays, the sunburn rays, are the ones that cause the most concern. They can cause keratitis, which is similar to sunburn on the eye, and also have been linked to the development of cataracts.
UVC rays are the shortest, the most energetic, and may be the most harmful. Fortunately, they are blocked in the upper atmosphere and never reach the earth. If sunglasses protect against UVB, we can assume they protect against any possible exposure to UVC.
Why are my lenses so thick?
Your prescription, your personal measurements, and the size of your frame are the three key factors that will determine final lens thickness. If you are farsighted your lenses will be thicker at their centre, in contrast, if you are nearsighted your lenses will be thicker at their edges. New innovative technology in lens designs, and materials, have allowed us to reduce overall lens thickness by as much as 60% in many cases. Our staff will guide you toward the best possible results in helping you choose the best frame-lens combination for your ocular and fashion needs.
Can the thick lenses be made thinner?
Absolutely! Newer, thinner lens materials are being developed all the time, and we pride ourselves in constantly being up-to-date with the latest developments and materials in the optical community. This, along with the proper grinding and appropriate frame selection could make your new fashion eyeglasses distinctly thinner. Ask one of our doctors or staff about the newest innovations in lenses today.
Can I use no-line bifocals with fashionably smaller frames?
Yes. Progressive lenses will allow you to use smaller frames while maintaining terrific vision at all distances. The visual channel that progresses from distance vision to near vision is wider, and more accurate for that 'Tween' vision necessary for clarity in the area too far for close, and to close for far. It is a wonderful lens for desk and computer use as well. Please note, that in a few of the especially small frames, not all frames can be a successful candidate for a progressive lens. With this in mind, our opticians will help you with a proper fit.
Can sunglasses help night vision?
If your eyes are subjected to intense glare during the day, they will "defend themselves" by trying to adapt. This natural built-in defense mechanism will persist for several hours after the glare is removed, resulting in reduced vision. Studies show that night vision can be reduced by as much as 50% by this exposure. Wearing sunglasses during the day dramatically improves night vision.
Do regular glasses protect my eyes from the sun?
Plastic lenses do not protect your eyes. You need to have UV protection from UV rays, which are not inherent in a plastic lens. You can have a UV protective coating applied to a plastic lens, but polycarbonate lenses have built-in UV protection. Glass lenses protect your eyes from harmful UVB rays but not from UVA. Some experts think UVA rays might have long-term, damaging effects to your eyes and skin.
What are all those numbers for my prescription?
An eyeglass prescription is written in a standardized format so it can be understood globally. The right eye, is generally referred to as "OD" or "R", while the left eye is generally referred to as "OS" or "L". The right eye is almost always on in a written prescription with the left directly below. Ignoring for sample sake, the right or left eye, let's look at a example below:
-2.00 -1.00 x 90. The first number (-2.00) tells us the spherical refractive diopter (a unit of measurement) needed to correct (farsightedness or nearsightedness). In this example, a minus sign in front of the number indicates a correction for nearsightedness. A plus sign would indicate a correction for farsightedness. This is generally true when you are talking about the first set of numbers.
The plus and minus signs on the second number, generally indicates what professional examined your eyes. An optometrist usually refracts in what's referred to as "Minus Cylinder, while an ophthalmologists refracts in "Plus Cylinder". For example, an optometrists script would be -2.00 -1.00 x 90, while the same prescription written by an ophthalmologists would be; -3.00 +1.00 x 180. Please note that the second number has a plus sign, and the last number (180, the Axis) has been transposed 90 degrees.
The second number (-1.00) is for astigmatism. If there is no astigmatism correction needed then you would not see the third (180) number. Sometimes you might see the following; SPH written for a cylinder correction instead of a number and nothing written for the third number. SPH stands for "Sphere" which indicates that there is no astigmatism correction needed.
The final number (180, the Axis line) is the direction of the astigmatism. Astigmatism can be measured in any direction around the clock. We use the numbers from 001 to 180 to indicate the orientation of the correction needed.
Depending on your need, there may be additional numbers in a eyeglasses prescription as well. If your prescription has a set of numbers, or a single number with a symbol such as a triangle, or the letters " BI, BO, BU, or BD that would indicate a prism correction. BI = Base In, BO = Base Out, BU = Base Up, and BD = Base Down. It is not uncommon to have different base directions for either eye.
Also, you will see "ADD" numbers for those requiring bifocals or reading glasses. The ADD number is exactly what it indicates...; an ADD, or an additional script to an otherwise already existing prescription. For example, your prescription is -2.00 for the first number. (In this example there is no astigmatism). For the "ADD " number you have a +3.00.This would indicate that by 'Adding" the +3.00 to the -2.00, your reading prescription would be +1.00 (adding a greater positive number to a lesser negative number results in a positive answer).
What is Ultraviolet (UV) and Infrared (IR) light?
The light we see with our eyes is really a very small portion of what is called the "Electromagnetic Spectrum." The Electromagnetic Spectrum includes all types of radiation - from the X-rays used at hospitals, to radio waves used for communication, and even the microwaves you cook food with.
Radiation in the Electromagnetic Spectrum is often categorized by wavelength. Short wavelength radiation is of the highest energy and can be very dangerous - Gamma, X-rays and ultraviolet are examples of short wavelength radiation. Longer wavelength radiation is of lower energy and is usually less harmful - examples include radio, microwaves and infrared. A rainbow shows the optical (visible) part of the Electromagnetic Spectrum and infrared (if you could see it) would be located just beyond the red side of the rainbow.
Ultraviolet light (UV) is an invisible light that is part of the sun's radiant spectrum. Exposure to ultraviolet light can cause the lenses of the eye to become cloudy, causing cataracts among many other conditions. Ultraviolet light causes the eye to age faster, thus can also cause macular degeneration. You can't see ultraviolet light. It affects the eye without your awareness to its being there, and the effects are cumulative. Almost everything in nature is affected by UV light, and almost everything deteriorates because of it. Not all sunglass lenses block all of the UV light, but the lens we recommend most is a polarized sunglass lens for sunglasses and polycarbonate lenses for dress wear.
Infrared (IR) is an invisible electromagnetic radiation that has a longer wavelength than visible light and is detected most often by its heating effect. Part of the discomfort you feel in your eyes after being out in the sun for a while is caused by IR light. Not all sunglass lenses block all of the UV light, but the lens we recommend most is a polarized sunglass lens for sunglasses and polycarbonate lenses for dress wear. Although infrared radiation is not visible, humans can sense it - as heat. Put your hand next to a hot oven if you want to experience infrared radiation "first-hand!
Eye test Sydney CBD optometrist or ophthalmologist?
Both are eye doctors that diagnose and treat many of the same eye conditions. The Optometric Association defines Doctors of Optometry as: primary health care professionals who examine, diagnose, treat and manage diseases and disorders of the visual system, the eye and associated structures as well as diagnose related systemic conditions. They prescribe glasses, contact lenses, low vision rehabilitation, vision therapy and medications as well as perform certain surgical procedures.
The main difference between the two, is that ophthalmologists perform surgery, where an optometrist would not, preferring to specialize in eye examinations, as well as eyeglass and contact lens related services.
Optometrists would be involved in all of the pre- and post-operative care of these patients; collecting accurate data, educating the patient, and insuring proper healing after the procedure. An ophthalmologist is more of a medical related specialist, who would need only to be involved if some kind of surgery were being considered. An optometrist can treat most any eye condition, including the use of ical or oral medications if needed. This might include the treatment of glaucoma, eye infections, allergic eye conditions and others, to name just a few.
A third "O" that often is overlooked, is the optician. An optician is not a doctor, and they cannot examine your eye under their own license. However, a highly trained optician plays an indispensable role in the most successful eye doctors' offices. An optician most often handles the optical, contact lens, and glasses side of things. Based on their vast knowledge of lenses, lens technology and frames, they manufacture eyeglasses, as well as assist in the selection of eyewear, based on the requirements of each individual patient.
Eye test Sydney CBD Visual Training?
First we need to understand what vision is. Nearly all humans are born with the potential for good eyesight, but vision – the ability to identify, interpret and understand what is seen – is learned and developed, starting at birth.
In learning to walk, a child begins by creeping, crawling, standing, walking with assistance, and finally, walking unaided. A similar process from gross to fine motor control takes place in the development of vision.
One visual skill builds on another, step-by-step as we grow. But many people miss a step, or do not complete a step, or must begin to perform school or other visually demanding tasks before an acceptable foundation of basic visual skill is in place.
Science indicates that we do not “see” with our eyes or our brain; rather, vision is the reception and processing of visual information by the total person. Since two-thirds of all information we receive is visual, it becomes clear that efficient visual skills are a critical part of learning, working and even recreation. Athletes, for example, use visual training for improved performance in their sport.
Developing visual skills includes learning to use both eyes together effectively. Having both eyes move, align, fixate and focus as a team enhances your ability to interpret and understand the potential visual information that is available to you.
Intelligent persons who are very highly motivated can be good achievers, even with very poor visual skills and abilities, but at untold cost in wasted energy and unnecessary effort and stress. For those who are less motivated, even one or two deficient visual skills can produce enough stress and frustration to create a non-achiever.
The visual skills which can be developed and enhanced through visual training include:
Tracking: The ability to follow a moving object smoothly and accurately with both eyes, such as a ball in flight or moving vehicles in traffic.
Fixation: The ability to quickly and accurately locate and inspect with both eyes a series of stationary objects, one after another, such as moving from word to word while reading.
Focus Change: The ability to look quickly from far to near and vice versa without momentary blur, such as looking from the chalkboard to a book or from the dashboard to cars on the street.
Depth Perception: The ability to judge relative distances of objects and to see and move accurately in three-dimensional space, such as when hitting a ball or parking a car.
Peripheral Vision: The ability to monitor and interpret what is happening around you while you are attending to a specific central visual task; the ability to use visual information perceived from over a large area.
Binocularity: The ability to use both eyes together, smoothly, equally, simultaneously and accurately.
Maintaining attention: The ability to keep doing any particular skill or activity with ease and with interfering with the performance of other skills.
Near Vision Acuity: The ability to clearly see, inspect, identify and understand objects at near distances, within arm’s length.
Distance Acuity: The ability to clearly see, inspect, identify and understand objects at a distance. People with 20/20 distance sight still may have visual problems.
Visualization: The ability to form mental images in your “mind’s eye,” retain or store them for future recall, or for synthesis into new mental images beyond your current or past direct experiences.
Optometric Brisbane visual training, sometimes called vision therapy or VT, is that part of optometric care devoted to developing, improving and enhancing people’s visual performance. Vision therapy can benefit people of all ages. Optometrists have developed and used visual training for several decades to:
Prevent vision and eye problems from developing.
Develop the visual skills needed to achieve more effectively at school, work or play.
Enhance functioning on tasks demanding sustained visual effort
Remediate or compensate for vision and eye problems which have already developed.
Visual training also has proven to be a remarkably effective tool in helping people with learning-related visual problems. Many problems in learning to read and write are made worse by poorly developed visual skills.
Dozens of experimental programs involving thousands of children and adults demonstrate that when visual skills are enhanced through visual training, learning is easier, reading levels rise, and in some cases, IQ scores have increased. Building visual skills also increases the ability to visualize, conceptualize and to create.
Vision therapy (visual training, vision training) is an individualized supervised treatment program designed to correct visual-motor and/or perceptual-cognitive deficiencies which have various causes, such as:
• inadequate sensorimotor development
• trauma to the nervous system (i.e., birth injury, brain trauma, closed head trauma, etc.)
• stress
• in some cases, contributing hereditary factors (i.e., crossed-eyes, wandering eyes)
Vision therapy trains the entire visual system which includes eyes, brain and body. However, it is important to understand that vision therapy is a form of neurological training or rehabilitation (it can be compared to some forms of occupational therapy or physical therapy). The goal of vision therapy is to train the patient's brain to use the eyes to receive information effectively, comprehend it quickly and react appropriately.
Vision therapy sessions include procedures designed to enhance the brain's ability to control eye alignment, eye movements, focusing abilities, and eye teamwork (binocular vision). Visual-motor skills and endurance are developed through the use of specialized computer and optical devices, including therapeutic lenses, prisms and filters. During the final stages of therapy, the patient's newly acquired visual skills are reinforced and made automatic through repetition and by integration with motor and cognitive skills.

Can I wear Contact Lenses?
With the newest contact lens designs and materials available today, our doctors are able to fit patients who may not have had success wearing contact lenses in the past. Whether due to poor vision, astigmatism, comfort issues, or dry eyes there are many more choices in contact lens materials to meet those challenges.
What types of Contacts Lenses are there and which lens is right for me?
There are several types of Contact lenses but only a thorough examination of your eyes AND your lifestyle will reveal the answer.
A few examples of Contact lenses are:
Daily Disposables
The shortest replacement schedule is single use (daily disposable) lenses, which are disposed of each night. These may be best for patients with ocular allergies or other conditions, because it limits deposits of antigens and protein. Single use lenses are also useful for people who use contacts infrequently, or for purposes (e.g. swimming or other sporting activities) where losing a lens is likely.
Two-week Replacement Disposables
The main advantage of wearing disposable lenses is that you put a fresh pair of lenses in your eyes every two weeks. Another advantage is ease of care with multipurpose solutions.
One-month Replacement Disposables
Similar to two-week replacement lenses but you throw them out every 30 days.
Conventional Contact Lenses
These are the original soft contact lenses. It is recommended these lenses be replaced on a yearly basis. Conventional lenses are more care intensive than disposable lenses.
Colour Contact Lenses
Certain soft contact lenses come in colours to either enhance your eye Colour or completely change it.
Toric for Astigmatism
Toric lenses are made from the same materials as regular contact lenses but have a few extra characteristics:
They correct for both spherical and cylindrical aberration.
They may have a specific '' and 'bottom', as they are not symmetrical around their centre and must not be rotated. Lenses must be designed to maintain their orientation regardless of eye movement. Often lenses are thicker at the bottom and this thicker zone is pushed down by the upper eyelid during blinking to allow the lens to rotate into the correct position (with this thicker zone at the 6 o'clock position on the eye). Toric lenses are usually marked with tiny striations to assist their fitting.
They are usually more expensive to produce than non-toric lenses
Bifocal Contact Lenses
Multifocal soft contact lenses are more complex to manufacture and require more skill to fit. All soft bifocal contact lenses are considered "simultaneous vision" because both far and near vision corrections are presented simultaneously to the retina, regardless of the position of the eye. Of course, only one correction is correct, the incorrect correction causes blur. Commonly these are designed with distance correction in the centre of the lens and near correction in the periphery, or vice versa..
What’s involved in a Contact Lens Exam?
In an initial exam, the eye doctor will examine your eyes to determine if you can wear contact lenses. Your prescription and the curvature of your eye are measured and the doctor will discuss any special needs you may have. The doctor will then determine the type of contact lenses that best fit your eyes and provide you with the most accurate vision while ensuring that your eyes remain healthy with the lenses. If trial lenses are available in the office, you may be able to go home with lenses the same day. However, if your prescription or curvature warrant, contact lenses may need to be ordered and a contact lens fitting appointment scheduled when the lenses arrive.
What’s involved in a Contact Lens Fitting?
When the lenses are ready, a fitting examination is scheduled as a practice session for you to try your new lenses and to become adept at lens insertion and removal. The doctor will also look at the lenses on your eyes and determine if any changes need to be made. If the lenses fit well and you are seeing well with them, a check-up exam is scheduled 1 week after the practice session. If new lenses are ordered, we will schedule a dispensing appointment when those lenses arrive.
Why is a yearly contact lens exam important?
Seeing 20/20 isn’t the only reason for a contact lens exam. Since the eye is a sensitive organ, it is susceptible to irritations that may be caused by contact lens wear. Problems that are undetectable to you can develop into more serious conditions. It is vital to your eye health to make sure that your contact lenses fit properly and are allowing enough oxygen to reach the cells of the cornea. During the annual contact lens exam, your eye care professional evaluates the condition of the lenses and can tell if any changes are warranted in the lenses’ fitting.
Can I swim or shower with contact lenses on?
There are two main reasons why you should not swim or shower with your contact lenses – possible loss of the lenses and, most importantly, contamination of the lenses. Underwater, contact lenses may be washed out of your eye, or above water a small wave or splash may take the lens with it. Contact lenses, especially the soft variety, will absorb any chemicals or germs in the water. They will then stay in or on the lens for several hours, irritating the eyes and possibly causing infection.
Eye test Sydney CBD Children Contact Lenses
The deciding factor for whether a child should wear contact lenses should be that child’s maturity level. Children of all ages can tolerate contact lenses well, but they must be responsible for the care of the lenses. Parents should make that judgment based on the child’s personal hygiene habits and their ability to perform household chores.
What is the difference between soft and hard Contact Lenses?
“Hard” lenses;
These lenses were the original contact lenses made several decades ago from a plastic called PMMA. For a long time they were the only kind of lens but they are seldom used anymore as they have several drawbacks and have been superseded by “rigid” lenses. Rigid, or gas permeable, lenses are similar to hard lenses in design and appearance, however as the name suggests, the material they are made of is permeable to gases.
“Soft” lenses;
Soft lenses are slightly larger and more flexible than rigid or hard lenses. Soft lenses are made of materials which soak up water, and it is this uptake of water that allows oxygen to transfer to the cornea. Soft lens material itself is impermeable, so the oxygen is transmitted via the water.
Why shouldn't I wear my two-week disposable lenses longer?
In order to maintain optimal eye health and comfort, it is important to adhere to the wearing schedule prescribed by your doctor..
What if I don't wear my two-week disposable contacts every day?
The two-weeks timeframe refers to 14 days of wear. If you are wearing lenses only two to three days per week, the lenses may last longer then two weeks.
Can I safely wear extended wear Contact Lenses overnight?
Extended lens wearers may have an increased risk for corneal infections and corneal ulcers, primarily due to poor care and cleaning of the lenses, tear film instability, and bacterial stagnation. Corneal neovascularization has historically been a common complication of extended lens wear, though this does not appear to be a problem with silicone hydrogel extended wear. The most common complication of extended lens use is conjunctivitis, usually allergic or giant papillary conjunctivitis (GPC), sometimes associated with a poorly fitting contact lens.
