Maintaining good eye health is essential for overall well-being, and taking vitamins can play a crucial role in keeping your eyes healthy. Certain vitamins can help prevent eye diseases and improve vision, so it's important to know which ones to include in your diet. In this article, we'll explore the vitamins that are good for your eyes and how they can benefit your vision.
Why Are Vitamins Good for Eyes?
Vitamins are essential for maintaining good eye health. Vitamins A, C, and E are particularly important for eye health1.
Vitamin A helps maintain a clear cornea, which is the outside covering of your eye2.
Vitamin C helps maintain healthy blood vessels in your eyes1.
Vitamin E helps prevent age-related macular degeneration (AMD), which is a leading cause of blindness1.
Other nutrients that are good for eye health include lutein and zeaxanthin, which are carotenoids that exist in high quantities in green leafy vegetables1.
Vitamins play an important role in maintaining good eye health. A diet rich in vitamins A, C, and E, as well as other essential nutrients including omega-3 fatty acids and zinc, is considered ideal for eye health3.
Let's take a look at some of these individual vitamins and their respective benefits below.
Vitamin A: Essential for good vision
Vitamin A is one of the most important vitamins for maintaining good eye health. Good sources of vitamin A include carrots, sweet potatoes, spinach, and liver.
Vitamin A plays a crucial role in maintaining good eye health4.
It helps maintain a clear cornea, which is the outside covering of your eye5.
Vitamin A is also a component of rhodopsin, a protein in your eyes that allows you to see in low light conditions4.
Without enough vitamin A, you may experience night blindness5.

Vitamin C: Protects against cataracts and macular degeneration
In addition to vitamin A, vitamin C is also important for maintaining good eye health. It is a powerful antioxidant that helps to protect the eyes from damage caused by free radicals. Good sources of vitamin C include citrus fruits, strawberries, kiwi, and bell peppers. Taking a daily multivitamin that includes vitamin C can also be beneficial for eye health.

Vitamin C is essential for maintaining good eye health. It helps produce collagen, which holds our eyes together and protects them. It also promotes the health of blood vessels throughout the body, including the retina’s delicate capillaries8.
If you’re not getting enough Vitamin C in your diet, you may be at risk for age-related eye disease9.
Vitamin E: Reduces the risk of age-related eye diseases
Vitamin E is another important nutrient for maintaining good eye health. Studies have shown that vitamin E can help to reduce the risk of age-related eye diseases such as cataracts and macular degeneration. Good sources of vitamin E include nuts, seeds, and leafy green vegetables. Taking a daily multivitamin that includes vitamin E can also be beneficial for eye health.
Vitamin E is a powerful antioxidant that is important to maintaining healthy eyes10.
It works in our bodies to help form red blood cells, improve immune function and specifically in our eyes, it can help to deactivate harmful free radicals, which are atoms of oxygen that can damage cells within the body (oxidative damage)10.
Vitamin E has also been found to act as a helper to the nutrient lutein, enhancing its antioxidant ability to protect delicate retinal pigment epithelial cells from oxidative damage10.
In fact, the National Eye Institute updated their guidelines recently for age-related eye disease study with the following recommendations: 400 IU vitamin E11.
Vitamin E is essential for maintaining good eye health. It helps deactivate harmful free radicals and enhances the antioxidant ability of other nutrients like lutein10.
If you’re not getting enough Vitamin E in your diet, you may be at risk for age-related eye disease11.
Zinc: Helps the body absorb Vitamin A and protects against macular degeneration
Zinc is an essential mineral that plays a crucial role in maintaining good eye health. It helps the body to absorb vitamin A, which is important for maintaining healthy vision. Good sources of zinc include oysters, beef, pork, and poultry. Taking a daily multivitamin that includes zinc can also be beneficial for eye health.
Zinc helps vitamin A create a pigment called melanin, which protects your eye12.
Research shows that at moderate levels, zinc protected retinal cells from antioxidant damage, which in humans might prevent age-related macular degeneration (AMD), a leading cause of blindness13. But at too-high levels, zinc helped destroy healthy retinal cells13.
Omega-3 Fatty Acids: Reduce the risk of dry eye syndrome and macular degeneration
Omega-3 fatty acids are essential nutrients that play a crucial role in maintaining good eye health. Good sources of omega-3s include fatty fish like salmon, tuna, and sardines, as well as flaxseed, chia seeds, and walnuts. If you don't eat enough of these foods, consider taking an omega-3 supplement to support your eye health.
Omega-3 fatty acids help ward off many eye diseases and help treat dry eye syndrome14.
Studies show consuming omega-3 fatty acids, whether in foods you eat or in a supplement, may help reduce your risk of developing macular degeneration and glaucoma14.
The American Academy of Ophthalmology (AAO) suggests that omega-3s are linked to preventing dry eyes and macular degeneration in adults15.
These fatty acids can also help ensure the eyes drain their fluids correctly, which in turn helps to prevent conditions such as glaucoma15.
Omega-3s are beneficial for eye health as they help ward off many eye diseases and help treat dry eye syndrome14. Consuming omega-3 fatty acids may also help reduce your risk of developing macular degeneration and glaucoma1514.
How to Optimize Diet for Good Eye Health
Eating a varied diet that includes lots of fruits, vegetables, and lean proteins is enough to ensure most people get the right nutrients for eye health.
People who cannot get these nutrients from their diet should ask an eye doctor about eye health supplements1.
On the other hand, foods that have saturated fats and high sugar can be detrimental to your eye health2.
Research says that foods rich in vitamins C and E, zinc, lutein, zeaxanthin, and omega-3 fatty acids are linked to lower risk for age-related macular degeneration (AMD), cataract and perhaps even dry eye later in life3.

Consuming omega-3 fatty acids may also help reduce your risk of developing macular degeneration and glaucoma.
If you’re concerned about your diet or have any questions about what foods are best for your eyesight, you should talk to your doctor or an eye specialist.
