To systematically evaluate evidences from randomized controlled trials on the effectiveness of antioxidant supplements in preventing the development and slowing the progression of age related cataract. Whether the same is true of isolated antioxidant vitamins, minerals, or polyphenols is less convincing, but as we gain a better understanding of the complexity of the mechanisms involved, there is increased potential to find diet or drug-derived antioxidant agents with beneficial effects, though not necessarily on account of their ability to directly scavenge radicals.
