Which of the following does not handle the oxidative damage in lens?

Glutathione, Catalase, Superoxide dismutase and Ascorbic acid (vitamin C) have been specially mentioned as true radical scavengers in relation to lens. Vitamin E (tocopherol) and J3 carotene are present in low levels in aqueous humor and may play a role in antioxidant mechanism in the lens.
