It is important to know that cataracts are not a form of disease. While cataracts cause blindness if left untreated, these are only present because the eyes age with time. Research suggests that by having good vitamin E levels in your diet, besides having ample carotenoids lutein and zeaxanthin, could reduce the risk of cataracts from occurring.
