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.
The American Optometric Association suggests that children should have their first regular eye exam at six months of age. Another vision exam should take place when a child is around two or three years of age when their vision undergoes its most rapid development and vision correction is most effective.
