Sweet Potatoes: Rich in vitamins C and A, sweet potatoes are high on the fruits and veggies list. Just one-cup serving of sweet potato has more than the full daily requirement for vitamin A. You can also try carrots if potatoes aren't your thing.

Kale, Spinach And Collards: High in vitamin A, these leafy greens contain antioxidants like lutein and zeaxanthin that protect and maintain healthy cells.

Oysters: Zinc deficiency has been linked to impaired vision, poor night vision, and cloudy cataracts, so getting plenty of the nutrient can certainly keep your eyes in check. Oysters are one of the best sources of zinc, as well as lobster, salmon, beef and milk. Increasing your zinc intake will also slow the progression of age-related macular degeneration, which is a common condition in adults age 50 and older.

Wheat Germ: High in Vitamin E, this also might slow down signs of macular degeneration and decrease risk of cataracts. Other tasty options include almonds, sunflower seeds, peanut butter and the aforementioned sweet potato.

Eggs: Here's another food that's relatively high in zinc. They're also a good source of Omega 3 fatty acids and lutein. And while they don't contain as much of that particular carotenoid as the leafy greens on this list, the body is better at absorbing these antioxidants.

Apricots: The thing about apricots is that they're a good source of carotenoids like beta carotene and lycopene. The body converts beta carotene into vitamin A, which resists damage to cells and tissues, including the eye lens.
