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.
Seniors over age 60 and individuals with risk factors should have an eye exam every year, or more frequently if recommended by their doctor. During this regular eye exam, you will need to ask your optometrist whether or not you need to replace your glasses with a new pair. Be sure to bring your old glasses with you so that your eye doctor can inspect them for flaws and durability.
