To help diagnose low vision, the complete eye exam usually begins with questions about your medical history and any vision problems you might be experiencing. It also involves a number of tests designed to evaluate your vision and check for eye diseases. Your doctor may use a variety of instruments, aim bright lights directly at your eyes, and ask you to look through an array of lenses.
Next, your doctor will check your eyes with a light to see whether the outside of your eyes are functioning correctly and whether there are any signs of injury or disease. Your eyes will also be tested for visual acuity, or how well you see.
Low vision is a permanent loss of vision that cannot be improved with eyeglasses, medicine or surgery. If you have been diagnosed with low vision, there is no treatment that will give you back your vision. Instead, you will need to learn new ways to use your remaining vision to complete everyday tasks and maintain your quality of life.
Remember, low vision is not a normal symptom of aging. Your Eye M.D. can tell the difference between normal changes in an aging eye and those caused by eye diseases. If you have noticed changes in your vision, see your eye doctor right away.
