Are Vitamins Essential for your Eyes?

Our eyes are sensitive organs, enabling us to see the colors of the world. Like every other organ, eyes require nutrients for normal functioning. Therefore, vitamins also play an essential function in maintaining the health of our eyes.

Before discussing the role of vitamins for eye health, we have to check out what vitamins are?


Vitamins are organic compounds that are generally required in small quantities but are essential for the normal functioning of your body; thus, they are micronutrients. Our body does not synthesize them; therefore, they must be taken with our diet to enjoy a healthy lifestyle. Vitamins regulate the metabolism of our body. Vitamins regulate many other functions of our body as well. Therefore, they are crucial for our eyes as well.

Vitamins for Eyes

Specific vitamins are necessary to keep our eyes healthy. Most vitamins act as powerful antioxidants, preventing the eyes from oxidative damage. Deficiencies of these essential vitamins can cause many problems for our eyes. They can also increase the risk rate of certain eye disorders such as glaucoma, contracts, and age-related macular degeneration (AMD). In this article, we shall enlist five essential vitamins and their role in a healthy eye.

Vitamin A and Beta Carotene

Vitamin A is essential for a healthy vision. It plays a crucial role in good vision by maintaining a clear cornea (the outside covering of your eyes). Thus vitamin A deficiency can reduce the lubrication of your eyes because the eyes produce too little moisture.

Vitamin A is its essential component. Our eyes contain a protein known as Rhodopsin which enables us to see in dim light. Therefore, Vitamin A deficiency is linked with night blindness.

Beta Carotene is a primary source of Vitamin A in our diet. This is a type of plant carotene found in vegetables and fruits. After consuming Beta carotene, these pigments are converted into Vitamin A, thus ready for our body to perform necessary functions.

Vitamin C

Vitamin C is a powerful antioxidant, thus protecting our bodily processes from free radicals and oxidative damage. Oxidative damage is a leading factor for age-related cataracts.

Vitamin C also has an essential function for producing a collagen protein that provides structure to your eyes, especially in the sclera and cornea.

Studies reveal that Vitamin C helps reduce the risk of developing cataracts (by almost 45%), a medical condition that causes impaired vision and eyes to become cloudy.

Vitamin C is found exclusively in citrus fruits and tropical fruits. Therefore, try using these foods in your diets to strengthen your eyes health.

Vitamin E

Vitamin E is also a powerful antioxidant, thus associated with oxidative stress. Free radicals can also damage your eyes and your vision.

Some studies reveal that there is also an association between Vitamin E and preventing cataracts. However, some research is required to confirm further.

Therefore, we should consider a diet having adequate levels of Vitamin E to maintain good eye health. Vitamin E is abundantly present in nuts, seeds, avocados, and leafy green vegetables.

Vitamin B3, B6, B9, and B12

Vitamin B also has a link with eye health, especially Vitamin B6, B9, and B12.

Vitamin B Combinations can lower the protein level known as homocysteine, which is linked with inflammation. In addition, homocysteine also increases the risk of AMD. Therefore, Vitamin B combinations are essential.

Vitamin B3 has been shown to reduce the risk of glaucoma, an eye disorder.

Vitamin B2 (Riboflavin)

Riboflavin is also a powerful antioxidant. Riboflavin also helps lower the risk of contracts; therefore, Vitamin B2 deficiency can increase contract risk.

Experts suggest that you may have a sufficient level of Vitamin B2 in your diet to have a good vision. Vitamin B2 is found exclusively in yogurt, milk, oats, and fortified cereals.


Eye health is significant for us to enjoy normal vision. The disorders are also well prevented by taking good supplements in our diet. Therefore, expert guidance is required to know more information.
