The most important foods for healthy eyes are those which are rich in vitamin A (beta carotene), vitamin C and vitamin E, according to the National Center on Health, Physical Activity and Disability.
All three play an important role in preventing macular degeneration and cataract formation.

In general, eating six to 10 daily servings of multicolored fresh fruits and vegetables will provide optimal nutrition for strong eyes. Like all other parts of the body, the eyes need specific nutrients to be healthy and strong.
