More and more research points to the importance of proper nutrition in the treatment and prevention of age-related eye diseases (AREDS). Several research studies have focused on the role of carotenoids in eye nutrition.

Carotenoids are an essential nutrient group derived from fruits and vegetables, especially dark green leafy vegetables. Carotenoids include vitamins A, C and E, which help promote and maintain healthy vision. 

Results from the age-related eye disease study show that zinc, copper and other antioxidants are also essential in maintaining healthy vision. Our bodies don't manufacture these nutrients on their own, so we must get them through our diet. 

Vitamin supplements are another way to provide our bodies with these nutrients.
