It is important to have your eyes examined regularly. Your eyes should be tested: before age 40, every two to four years. from age 40 to age 54, every one to three years. from age 55 to 64, every one to two years. after age 65, every six to 12 months.
As a rule, you should not go more than two years without having your eyes examined. Diabetic patients, people with a family history of eye diseases, and anyone whose general health is poor or who is taking medications that may have potential side effects on the eye may need an eye exam at least once a year.
