Experts have proved through years of research that cataract is an entirely avoidable condition in old age by taking enough of vitamin supplements. The power of vitamins has been known to fight against the serious effects of free radicals. The oxidization effect of the free radicals would be offset by the vitamins that nourish the cells of different organs. Vitamin A is known already as a vitamin for good vision while Vitamin B has now been proved to fight against cataract formation. Vitamin C would protect the eye lens and keep it safe from any deposits that would hamper good vision.
