Vitamin E

Many eye disorders are thought to be caused by oxidative stress, which is an imbalance in your body's antioxidants and free radicals. Vitamin E is a powerful antioxidant that protects your cells, especially your eye cells, from free radical damage. Free radicals are destructive, unstable chemicals. A seven-year study of 3,640 persons with AMD found that taking 400 IU (international unit) of vitamin E and many other nutrients daily in a supplement called age-related eye disease studies (AREDS) lowered the probability of advancing to advanced stages by 25%.

Furthermore, some research suggests that vitamin E-rich diets may help prevent age-related cataracts. More study is needed, however, because some studies suggest no link between vitamin E and this illness. Nonetheless, a diet rich in vitamin E is suggested to preserve good eye health. Nuts, seeds, and cooking oils are all high in vitamin E. Salmon, avocado, and leafy green vegetables are also high in vitamin D.
