One of the keys to cataracts is a healthy diet.  Foods high in fats and salt hurt your cataracts while foods rich in antioxidants help to destroy free radicals which can hart your cataracts.

Apple cider vinegar is good for your cataracts because it is rich in antioxidants (thanks to vitamins C, E and Beta-Carotene) but also because it can metabolize fats and proteins which is great for your eyes.
