Raw Red Peppers
Bell peppers give you the most vitamin C per calorie. That’s good for the blood vessels in your eyes, and science suggests it could lower your risk of getting cataracts. It’s found in many vegetables and fruits, including bok choy, cauliflower, papayas, and strawberries. Heat will break down vitamin C, so go raw when you can. Brightly colored peppers also pack eye-friendly vitamins A and E.
Sunflower Seeds and Nuts
An ounce of these seeds or almonds has half the amount of vitamin E the USDA recommends for adults each day. A large study found that vitamin E, together with other nutrients, can help slow age-related macular degeneration (AMD) from getting worse. It may also help prevent cataracts. Hazelnuts, peanuts (technically legumes), and peanut butter are also good sources of vitamin E.
Dark, Leafy Greens
Kale, spinach, and collard greens, for example, are rich in both vitamins C and E. They also have the carotenoids lutein and zeaxanthin. These plant-based forms of vitamin A lower your risk of long-term eye diseases, including AMD and cataracts. Most people who eat Western diets don’t get enough of them.
Your retinas need two types of omega-3 fatty acids to work right: DHA and EPA. You can find both in fatty fish, such as salmon, tuna, and trout, as well as other seafood. Omega-3s also seem to protect your eyes from AMD and glaucoma. Low levels of these fatty acids have been linked to dry eyes.
Orange-colored fruits and vegetables — like sweet potatoes, carrots, cantaloupe, mangos, and apricots — are high in beta-carotene, a form of vitamin A that helps with night vision, your eyes’ ability to adjust to darkness. One sweet potato also has more than half the vitamin C you need in a day and a little vitamin E.
