Good dietary sources of vitamin A include sweet potatoes, carrots, spinach, kale and cantaloupe. Taking a vitamin A supplement between 2500-5000 IU per day can help support eye health, especially for those with restricted diets.

Lutein and zeaxanthin are carotenoid antioxidants found in high concentrations in the macula region of the eyes. They help filter harmful blue-violet and blue-green light and protect against light-induced damage. Most Americans do not get enough lutein and zeaxanthin through their diets. Supplementing with 10-20 mg of these carotenoids daily may help support macular health and reduce risk of age-related macular degeneration (AMD), a leading cause of blindness. Good food sources include kale, spinach, collard greens and eggs from hens fed marigold extract.

Vitamin C for Eye Health Supplements
