Posted by Chantel M. Contributed by US National Library of Medicine National Institutes of Health

In the study of "The effect of vitamin C deficiency and chronic ultraviolet-B exposure on corneal ultrastructure: a preliminary investigation" by Hayes S, Cafaro TA, Boguslawska PJ, Kamma-Lorger CS, Boote C, Harris J, Young R, Hiller J, Terrill N, Meek KM, Serra HM., posted in US National Library of Medicine National Institutes of Health, found that UVB-induced changes in the corneal ultrastructure were most pronounced in animals fed an ascorbic acid-deficient diet. This suggests that ascorbic acid may play a vital role in protecting the corneal stroma from the harmful effects of UVB.
