Zexanthin / luteins and omega 3 have been the main substances studied in this relation.

Although benefits of the regimens with high amounts of antioxidants were observed in reducing progression of cataract, age related macular degeneration and so on, as many of these studies have been observational, the cause and effect relationship cannot be definitely concluded and multiple cohort prospective studies will be desired to evaluate the exact role of nutrition.
