Dark leafy greens, carrots, pumpkin, sweet potatoes, yellow peppers and egg yolks contain potent antioxidants like beta-carotene, zeaxanthin and lutein -- which defend against age-related blindness resulting from macular degeneration. Drinking freshly pressed carrot juice, at least twice per day, is an excellent habit that keeps eye problems at bay.
Foods high in sulfur, lecithin and cysteine are another helpful addition to the diet. Examples include garlic, onions, shallots, leeks, tree nuts, dairy, coconut and legumes. These edibles fortify the lens of your eye, thereby reducing the risk of cataracts.
Blueberries, black currant, acai and goji berries are chock-full of anthocyanin -- a powerful antioxidant and anti-inflammatory that substantially improves eye health.
Coldwater fish like salmon, sardines and mackerel provide abundant essential fatty acids that help support cell membranes, which in turn, encourages sharp vision.
Additionally, vitamins C and E, along with the minerals zinc and copper, are useful in maintaining healthy eyesight. Citrus fruits, broccoli and Brussels sprouts are good sources of vitamin C, while tree nuts (especially almonds) are high in vitamin E and copper. Pastured beef, wild game and eggs are rich in zinc.
