Frequently Asked Questions and Myths
We have all been told by someone at some time, “You’ll hurt your eyes if you do that!” But do you really know what is or is not good for your eyes? Test yourself with the following true or false statements and see how much you know about your eyes.
READING IN DIM LIGHT IS HARMFUL TO YOUR EYES
False. Using your eyes in dim light does not damage them. For centuries, all nighttime reading and sewing was done by candlelight or with gas or kerosene lamps. However, good lighting does make reading easier and can prevent eye fatigue.
CHILDREN OUTGROW CROSSED OR MISALIGNED EYES
Children do not outgrow crossed eyes. A child whose eyes are misaligned may develop poor vision in one eye because the brain will “turn off” or ignore the image from the misaligned or lazy eye. The unused or misaligned eye will not develop good vision unless it is forced to work. This is usually accomplished by patching the stronger eye. Children who appear to have misaligned eyes should be examined by an ophthalmologist as soon as possible. In general, the earlier misaligned eyes are diagnosed and treated, the better. Treatment may include patching, eyeglasses, eyedrops, surgery or a combination of these methods.
EATING CARROTS IMPROVES VISION
Carrots are rich in vitamin A, which is essential for sight, but many other foods also contain this vitamin. A well-balanced diet, with or without carrots, provides all the vitamin A necessary for good vision.
OLDER PEOPLE WHO GAIN 'SECOND SIGHT' MAY BE DEVELOPING CATARACTS
Older individuals who wear reading eyeglasses sometimes ﬁnd themselves able to read without their eyeglasses and think their eyesight is improving. The truth is they are becoming more nearsighted, which can be a sign of early cataract development.
WILL MY VISION OR MEDICAL INSURANCE HELP WITH MY EXAM?
Often Times, Yes!
We accept most vision insurances, and benefits vary from plan to plan. Feel free to call and ask what your insurance covers.
Many of our patients are not aware that their medical insurance will often pay for an eye exam, including Medicare, Oregon Health Plan, and most other insurances. These insurances will pay for the exam if there is a qualifying underlying medical problem, such as cataracts (nearly all patients over age 60 have some degree of cataract), dry eye (also quite common in our dry climate), Diabetes, Glaucoma, Macular degeneration, and many more. Medical insurance will usually NOT pay for a pair of glasses, but they will pay for the exam. However, a measurement for glasses can be done at the time of the exam, and a prescription given if the patient desires (refraction fees apply.)
Oregon Health Plan will pay for an exam and a pair of glasses yearly for children (Age 0-20) regardless of whether there is an underlying medical problem or not. They will also cover an exam and a pair of glasses for pregnant OHP clients that provide a “Proof of Pregnancy” document from their Primary Care or OB provider
If you don’t have Vision or Medical insurance, we are still happy to see you!
USING COMPUTERS CAN DAMAGE YOUR EYES
Looking at computer monitors will not harm your eyes. Often, when using a computer for long periods of time, just as when reading or doing other close work, you blink less often than normal. This reduced rate of blinking makes your eyes dry, which may lead to the feeling of eyestrain or fatigue. Try to take regular breaks to look up or across the room. Looking at objects farther away often relieves the feeling of strain on your eyes. Keep the monitor between 18 to 24 inches from your face and at a slight downward angle. Also consider the use of artiﬁcial tears. If your vision blurs or your eyes tire easily, you should have your eyes examined by an ophthalmologist.
WEARING EYEGLASSES WILL CAUSE YOU TO BECOME DEPENDENT ON THEM
Eyeglasses are used to correct blurry vision. Since clear vision with eyeglasses is preferable to uncorrected vision, you may ﬁnd that you want to wear your eyeglasses more often. Although it may feel as if you are becoming dependent on your eyeglasses, you are actually just getting used to seeing clearly.
PEOPLE WITH WEAK EYES SHOULD AVOID READING FINE PRINT
It is said that people with weak eyes or people who wear glasses will “wear out” their eyes sooner if they read ﬁne print or do a lot of detail work. The concept of the eye as a muscle is incorrect. The eye more closely resembles a camera. A camera will not wear out sooner just because it is used to photograph intricate detail. You can use your eyes without fear of wearing them out.
A CATARACT MUST BE 'RIPE' BEFORE IT IS REMOVED
With older surgical techniques, it was thought to be safer to remove a cataract when it was “ripe.” With today’s modern surgical procedures, a cataract can be removed whenever it begins to interfere with a person’s lifestyle. If you are unable to see well enough to do the things you like or need to do, you should consider cataract surgery. Surgery is the only way to remove a cataract.
EYES CAN BE TRANSPLANTED
Medical science has no way to transplant whole eyes. Our eyes are connected to the brain by the optic nerve. Much like a fiber optic cable, the optic nerve is made up of more than one million tiny nerve ﬁbers. This nerve cannot be reconnected once it has been severed. Because of this, the eye is never removed from its socket during surgery. The cornea, the clear front part of the eye, has been successfully transplanted for many years. Corneal transplant is sometimes confused with an eye transplant.
WEARING THE WRONG KIND OF EYEGLASSES DAMAGES YOUR EYES
Eyeglasses are devices used to sharpen your vision. Although correct eyeglasses or contacts help you to see clearly, wearing a pair with the wrong lenses, or not wearing glasses at all, will not physically damage your eyes but may cause eye fatigue or strain. However, children younger than 8 years old who need eyeglasses should wear their own prescription to prevent the possibility of developing amblyopia or “lazy eye.”
SITTING CLOSE TO THE TELEVISION CAN DAMAGE CHILDREN'S EYES
Children can focus at close distance without eyestrain better than adults. They often develop the habit of holding reading materials close to their eyes or sitting right in front of the television. There is no evidence that this damages their eyes, and the habit usually diminishes as children grow older. However, children with nearsightedness (myopia) sometimes sit very close to the television in order to see the images more clearly, so they should have an eye examination.
LEARNING DISABILITIES ARE CAUSED BY EYE PROBLEMS
Difficulties with reading, mathematics, and other learning problems in children are often referred to as learning disabilities. There is no strong evidence that vision problems cause learning disabilities or that eye exercises cure learning problems. Children with learning difficulties often need help from teachers and people with special training. Before such treatment begins, it is important for the child to have a complete medical eye examination to make certain he or she is seeing as well as possible.
CONTACT LENSES CAN PREVENT NEARSIGHTEDNESS FROM GETTING WORSE
Some people have been led to believe that wearing contact lenses will permanently correct nearsightedness so that eventually they won’t need either contacts or eyeglasses. There is no evidence that wearing contact lenses produces a permanent improvement in vision or prevents nearsightedness from getting worse.
ALL 'EYE DOCTORS' ARE THE SAME
False. An ophthalmologist is a medical doctor (M.D. or D.O.) with special training to diagnose and treat all diseases of the eye. To become an ophthalmologist requires a minimum of eight years of medical school and hospital training after college. An ophthalmologist is qualified to provide all aspects of eye care, including cataract, laser and other eye surgery. Optometrists (O.D.) and opticians are other types of eye care professionals. They are trained and licensed to provide some aspects of eye care, but they are not medical doctors and have not attended medical school. In most states, they cannot prescribe all medications or perform surgery.
