ABSTRACT
The aim of the present study was to evaluate the effects of diets containing L-ascorbic acid on
the morphology of the eye lens in rats. The experiment was done on 40 Wistar rats. The animals
were divided into 4 groups fed diets containing: I – 0.0; II – 0.3; III – 0.6, or IV – 0.9% of L-ascorbic acid.
Vitamin C megadoses (0.6 and 0.9%) caused an increase in lens capsule thickness and changes in its
structure (an increase in the neutral glycoprotein content) and activity of the epithelial cells under
the capsule.
