Oxidative stress‐induced toxicity plays a major role in ocular diseases such as retinal degeneration, age‐related cataract (ARC) formation and macular dystrophy. In this study, we explored the possible role of resveratrol (RSV) at the different dose levels (10, 20 and 40 mg/kg/day, ip) in an experimental model of naphthalene (1 g/kg/day, po)‐induced age‐related cataracts. Morphological changes in the eyes of the rats in two groups, the RSV and the ARC groups, were monitored weekly, and biochemical parameters in the lenses were assessed after completion of the experimental work. A comparison between the rats in the two groups showed that treatments at RSV doses of 20 and 40 mg/kg/day significantly retarded lenticular opacity, restored antioxidants (CAT, SOD, GPX, GSH), Ca 2+ ATPase function, and protein contents, and reduced lipid peroxidation in the lenses of the animals in the RSV group. The treatment with resveratrol at a dose of 10 mg/kg/day did not show any anti‐cataractogenic effects. Based on the results of our investigation, we conclude that supplemental doses of resveratrol at 40 mg/kg/day effectively prevent cataract formation associated with the aging via increased soluble protein contents and Ca 2+ homeostasis, apart from the antioxidant restoration. The results demonstrate that RSV treatment may be considered as a promising preventive or supplemental measure for delaying and/or preventing the formation of ARCs.
