In general, eye exams are recommended annually, and more frequently for those with certain conditions or who have a family history of eye problems. If your eyes are healthy and vision is good, an adult should have a complete baseline exam by an ophthalmologist once in their 20s and twice in their 30s. The American Academy of Ophthalmology recommends that adults get a complete eye exam at the age of 40, when early signs of disease or changes in vision may appear. Early detection of eye problems is important as early treatment can help preserve your vision.
