doctor2020eyes@yahoo.comCataract development and the need for cataract surgery appear to be significantly reduced by the use of Lutein and Zeaxanthin. There are 4 recent observational or epidemiological studies: Nurses’ Health Study, Health Professional’s Follow-Up Study, Beaver Dam Eye Study and a Study of 372 men and women ages 66 -75 in England. All showed a positive relationship between higher consumption levels (6 mg) of Lutein and Zeaxanthin with a lowered risk of cataract development and the need for cataract surgery.
Vitamins B2 and B3 protect Glutathione (Molecule composed of 3 amino acids) which is an important antioxidant in the eye. Studies have shown that deficiencies in B2 and B3 increase the risk for cataracts.
Vitamin C and Glutathione are the major antioxidants of the crystalline lens inside the eye. This clear crystalline lens is what becomes cloudy and is then called a cataract. Vitamin C levels in the eye normally decrease with age which appears to contribute to cataracts. Vitamin C levels can be kept up with supplementation. Vitamin activates Vitamin E which activates Glutathione.
Low levels of Vitamin E also increase the risk for cataracts. Studies show that people who have taken Vitamins C and E for more than 10 years have a 60% lower risk of developing cataracts. I believe that the best nutritional supplements for Possible Treatment of Known Cataracts are Ocupower plus 10 mg of ZeaVision’s Eye Promise 5 or for Possible Prevention of Cataracts are Ocupower Basic plus 5 mg of ZeaVision’s Eye Promise 5. This combination has great forms and amounts of all of the Vitamins and Nutrients currently shown to have benefits for Cataracts. The following are charts showing foods with good sources of Vitamins C and E as well as Lutein and Zeaxanthin.
