Zeaxanthin is a powerful antioxidant found in nature and is one of three carotenoids found in large quantities in the human eye, according to All About Vision. Several benefits associated with zeaxanthin are described by WebMD, including improved vision, protection from some ultraviolet rays, prevention of cataracts, and slower progression of eye disease, such as macular degeneration.

More that 25 million people worldwide are afflicted with cataracts and age-related macular degeneration, and the incidence rates are growing, claims the American Optometric Association. The body does not make sufficient amounts of zeaxanthin, so it is important to support eye health through proper dietary intake and supplements. Green vegetables, including spinach, kale, collards, turnip greens, and broccoli, are listed by WebMD as the richest in zeaxanthin. Other sources include corn, green peas, green beans and romaine lettuce, as reported by the American Optometric Association. It is uncertain whether or not supplements of zeaxanthin provide equal benefits to eye health as food sources, according to All About Vision.
