Research has also been done on many different vitamins and minerals as they relate to free radical control. Vitamin C is a water-soluble vitamin and a very powerful antioxidant. The vitamin C content of the eye is many times higher than that of the blood serum. Therefore, getting enough in the daily diet is very important to keep these level up enough to prevent free radical damage. Research shows that it takes at least 1,000mg of vitamin C to boost the levels in the eye.
Vitamin E is a fat-soluble vitamin.
Research has shown that cataract lenses are extremely low in selenium and that supplementation with selenium can greatly reduce the risk of cataracts. Vitamin E is a potent antioxidant for cell membranes. Together, they work better to protect against free radical damage than either one alone. Not only is it a powerful antioxidant, but it also protects against light-induced damage to the lens. One car rot per day will give you plenty of protection at very little cost.
