But everyone needs regular eye exams. This is particularly important if you have risk factors or a family history of eye problems. Children need their vision checked at 6 months, 3 years, and before first grade. These exams should be done during preventative pediatrician visits and with a pre school eye screening. Adults should see an eye doctor at least every two years and annually after age 60.
Vitamin E is a potent antioxidant that exists in different forms. Alpha-tocopherol vitamin E is the form that best meets our needs. Vitamin E's main role in the body appears to be neutralizing oxidation. For that reason, researchers think it plays an important role in protecting certain parts of the eye, which is particularly susceptible to oxidative damage. Cataracts, for example, are believed to be formed by oxidation in the lens of the eye caused mostly by UV rays in sunlight.
Your doctor may recommend more frequent exams if you have a health condition such as diabetes or high blood pressure, work in a visually demanding job, or take medications that can affect eyesight.
Preparing for Your Eye Exam
When you call to make an appointment for an eye exam, briefly and clearly describe any vision problem you're having.
Before you go, list questions for the eye doctor. Be prepared to discuss any drugs you're taking and your (and your family's) eye health history.
When you go, take your glasses and/or contact lenses, if you use them, and sunglasses for the trip home with your pupils dilated.
During Your Eye Exam
Before your eye exam, the eye doctor or an office staff member will take your medical and vision history.
Your eye exam may take from half an hour to an hour. It will evaluate both your vision and the health of your eyes.
You'll likely have all or most of the following eye tests (you may also have more specialized eye tests):
Eye muscle movement test: To assure that the eyes are normally aligned, the doctor will ask you to visually track a target in different directions and observe your eye movements.
Cover test: This is a check for how well your eyes work together. As you stare at a small target some distance away, the doctor will cover and uncover each eye to observe how much your eyes move, watching for an eye that turns away from the target (strabismus). The test may be repeated with a target close to you.
