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 Academy of Ophthalmology recommends that you get a baseline eye examination at age 40, the time when early signs of disease or changes in vision may occur. Much like a screening for diabetes or certain cancers, a baseline eye exam at 40 is a reminder to adults as they age to be aware of their eye health.
