Do eye vitamins improve vision?

Improving eyesight without glasses

While there are many causes for blurry vision including needing prescription eyeglasses, excessive digital screen use and eye infections, vitamins have been shown to help keep the eyes healthy and lower the risk of certain eye diseases. Many of these vitamins can be found as a supplement or be consumed through a healthy diet.

What are the best vitamins for your eyes?

Vitamin A, C and E are powerful antioxidants that help protect the retina against oxidative damage, which can lead to vision threatening diseases like macular degeneration. Vitamin C has also been shown to decrease the risk of cataracts. Lutein and zeaxanthin are a part of a group of antioxidants called carotenoids. Carotenoids make up the pigment found in fruits and vegetables as well as the protective pigment found in the retina. Increased intake of carotenoids, like lutein and zeaxanthin, have been shown to protect against cataracts, macular degeneration, and other retinal diseases. The body is unable to make carotenoids, therefore they need to be obtained through diet.

Are omega-3 fatty acids good for the eyes?

Yes. Research has shown that consuming omega 3-fatty acids has been shown to lower the risk of macular degeneration. It has also been shown to improve symptoms of dry eye disease, as it improves the function of the glands in the eyelids that produce the lipid or oily layer of the tear film. An intact tear film is essential for maintaining a healthy ocular surface, which contributes to optimal vision. It has also been shown to reduce ocular surface inflammation which improves dry eye symptoms.

Is biotin good for the eyes?

Biotin, aka vitamin B7, has not been shown to prevent eye disease. However, vitamins B6, B9 and B12 have been shown to reduce chronic inflammation and can help decrease the risk of macular degeneration.

What foods improve eyesight naturally?

A healthy diet is essential in maintaining good vision and protecting against eye disease. Dark green leafy vegetables such as spinach and kale are high in lutein and zeaxanthin. Lutein can also be found in egg yolks, broccoli, and corn. Colorful fruits and veggies such as carrots, blueberries, strawberries, and goji berries are rich in antioxidants. Vitamin C is abundant in oranges, grapefruit, and tomatoes and Vitamin E can be found in sweet potatoes, nuts, and vegetable oils. Fatty fish such as salmon, sardines and mackerel contain high levels of omega 3-fatty acids.
