Our eyes need many different vitamins and nutrients to function properly. Nutrition seems to be the common denominator for all types of conditions that can impact our eyes, at least in part. A consistent intake of the following vitamins can help maintain good eye health, now and in the future.
Vitamin A is vital in maintaining a clear cornea, which is the outside covering of your eye. It’s also a component of rhodopsin, a protein in your eyes that allows you to see in low light conditions
A lot of eye conditions are thought to be associated with oxidative stress, which is an imbalance between antioxidants and free radicals in your body
Vitamin E is a potent antioxidant that helps protect your cells — including your eye cells — from damage by free radicals, which are harmful, unstable molecules.
Vitamin C forms collagen which is a protein that provides structure to your eyes. Some studies suggest that this vitamin may protect against cataracts and help prevent the progression of AMD (Age-related macular degeneration).
Combined, B6, B9 and B12 can lower levels of homocysteine, a protein in your body that may be associated with inflammation and an increased risk of developing AMD.
Another B vitamin studied in relation to eye health is riboflavin (B2). As an antioxidant, riboflavin has the potential to reduce oxidative stress in your body, including your eyes.
The main function of niacin (B3) is to help convert food into energy. It can also act as an antioxidant. Recently, studies have suggested that niacin may play a role in the prevention of glaucoma, a condition in which the optic nerve of your eye becomes damaged.
Lutein and zeaxanthin are part of the carotenoid family, a group of beneficial compounds synthesized by plants.
Both can be found in the macula and retina of your eyes, where they help filter potentially harmful blue light, protecting your eyes from damage
Omega 3 fatty acids are a type of polyunsaturated fat.
Besides helping form the cells of your eye, omega-3 has anti-inflammatory properties which may play a role in the prevention of diabetic retinopathy.
Thiamin, or vitamin B1, plays a role in proper cell function and converting food into energy. It’s possibly effective at reducing the risk of cataracts.
