Maintaining good eye health involves a combination of a balanced diet, lifestyle choices, and, when necessary, specific supplements. Vitamins and nutrients known to support eye health include vitamins C and E, lutein, zeaxanthin, zinc, and omega-3 fatty acids. Here are some details on these nutrients and popular ocular supplements:
Vitamins and Nutrients for Eye Health
Vitamin C
Benefits: An antioxidant that helps protect the eyes from free radical damage. It supports the health of blood vessels in the eyes and may reduce the risk of cataracts and age-related macular degeneration (AMD).
Sources: Citrus fruits, strawberries, bell peppers, broccoli, and kale.
Vitamin E
Benefits; Another powerful antioxidant that protects eye cells from damage. It may also play a role in preventing cataracts and AMD.
Sources: Nuts, seeds, spinach, and broccoli.
Lutein and Zeaxanthin
Benefits: These carotenoids are found in high concentrations in the retina and lens of the eye. They filter harmful blue light and protect eye tissues from damage. They are linked to a reduced risk of chronic eye diseases, including AMD and cataracts.
Sources: Leafy greens like spinach, kale, and broccoli, as well as corn and eggs.
Zinc
Benefits: Essential for bringing vitamin A from the liver to the retina to produce melanin, a protective pigment in the eyes. It may also help slow the progression of AMD.
Sources: Meat, shellfish, legumes, seeds, nuts, and dairy products.
Omega-3 Fatty Acids
Benefits: Important for proper visual development and retinal function. They can help reduce dry eye symptoms and may lower the risk of AMD.
Sources: Fatty fish like salmon, mackerel, and sardines, as well as flaxseeds and chia seeds.
