A variety of vitamins can improve your eyesight and keep your eyes healthy and strong.

The exact cause of poor eyesight varies, but age, diseases, injuries, infections and certain medical conditions such as macular degeneration, diabetes and cataracts can affect your eyesight and cause blurriness, blind spots and decreased vision. A variety of vitamins can improve your eyesight and keep your eyes healthy and strong.

Vitamin A
Vitamin A is a fat-soluble vitamin that can strengthen your immune system and protect your eyes from viral and bacterial infections. Vitamin A can protect the linings of your eyes, improve eyesight in low light, reduce retina and cornea scarring, prevent permanent retina damage after eye injury and lower your risk of blindness. The recommended daily allowance for vitamin A is 5,000 international units, or IU, for adults. Foods rich in vitamin A include liver, milk, carrots, pumpkin, kale, tomatoes, spinach and sweet potatoes.

Vitamin B-2
Vitamin B-2, also known as riboflavin, is a water-soluble vitamin that can protect your eyes’ natural lenses from damage, aid in red blood cell production and cellular metabolism, repair damaged tissues, prevent age-related vision loss, eliminate cloudy vision and decrease your risk of developing cataracts. The recommended daily allowance for vitamin B-2 is 1.7 mg for men and 1.3 mg for women. Foods rich in vitamin B-2 include beef tenderloin, venison, lettuce, asparagus, collard greens, broccoli, eggs, yogurt and milk.

Vitamin C
Vitamin C is a water-soluble antioxidant that can boost immune system function and protect your eyes from damaging free radicals. Vitamin C can aid in blood vessel formation, help form connective tissues in the cornea, decrease pressure in your eyes, improve visual acuity, and lower your risk of developing cataracts and macular degeneration, an eye disease that destroys central vision. The recommended daily allowance for vitamin C is 1,000 mg for adults. Foods rich in vitamin C include red peppers, tomatoes, broccoli, kale, cranberries, pineapples, grapefruits, strawberries, spinach, oranges and kiwi.

Vitamin E
Vitamin E is a fat soluble vitamin that can improve immune system function, decrease inflammation in your eyes, improve visual clarity, increase blood flow to your eyes and prevent eye conditions such as macular degeneration, cataracts and blindness. The recommended daily allowance for vitamin E is 15 mg for adults. Foods rich in vitamin E include peanuts, almonds, hazelnuts, mangoes, tomatoes, broccoli, kiwi and corn oil.
