Cataracts typically form as the tissues within the lens in your eye break down and form clumps. These clumps cause clouded areas on your eye, which in turn impair your eyesight. These clumps are the results of free radicals( red blood cells out of control) that damage your eyes and the rest of the body. To combat the destructive action of free radicals, you need to consume antioxidants in food or supplemental form. Antioxidants are found in dark colored (green, red, purple, and yellow) fruits and vegetables. Research emphasizes the importance of lutein ( found in dark colored fruits and vegetables such as tomatoes and kale) for protecting against cataracts and other degenerative eye diseases.
