| Abstract: | Abstract— The antioxidant vitamin E (α-tocopherol) may protect both animal and plant cell membranes from light-induced damage. The various biochemical and biophysical modes of protection are considered. An examination is made of the evidence that vitamin E plays an important prophylactic role against a number of serious light-induced diseases and conditions of the eye (cataractogenesis and retinal photodeterioration) and skin (erythrocyte photohem-olysis, photoerythema, photoaging and photocarcinogenesis) that are mediated by photooxidative damage to cell membranes. |
