Lutein and zeaxanthin are recommended at least as an appropriate cautionary measure, especially for p...
متن کاملAntioxidant intake and risk of incident age-related nuclear cataracts in the Beaver Dam Eye Study.
The relation of antioxidant nutrients to the incidence of nuclear cataracts was investigated in a cohort of adults aged 43-84 years in the Beaver Dam Eye Study (Beaver Dam, Wisconsin). Nuclear opacity was assessed on a five-point ordinal scale using lens photographs taken at baseline (1988-1990) and at follow-up (1993-1995). Of the 1,354 persons eligible, 246 developed a nuclear cataract (level...
متن کاملNatural therapies for ocular disorders, part two: cataracts and glaucoma.
Pathophysiological mechanisms of cataract formation include deficient glutathione levels contributing to a faulty antioxidant defense system within the lens of the eye. Nutrients to increase glutathione levels and activity include lipoic acid, vitamins E and C, and selenium. Cataract patients also tend to be deficient in vitamin A and the carotenes, lutein and zeaxanthin. The B vitamin riboflav...
