Understanding How Vitamin A Helps The Eyes

If you care about your eyesight, then you likely know that you should see your optometrist or ophthalmologist once every year or two. This will allow the professional to evaluate your visual acuity as well as the general health of your eyes. The eye doctor can greatly assist you in retaining the health of your eyes. However, you also need to do your part by eating a healthy diet. A diet high in vitamin A is essential. Keep reading to learn why and to find out which foods provide the vitamin.

How Does Vitamin A Assist The Eyes?

Vitamin A plays a vital role in keeping your eyes in good condition. One of the most important things the vitamin does is keep the cornea healthy. The cornea is the clear outer coating of the eye that protects the inner tissues from damage. Vitamin A helps to keep the cornea properly lubricated by helping the body create tears. Without the lubrication, the cornea can become dry and cracked. Vitamin A also helps the eyes form photoreceptors along the retina, and this allows you to see well in the dark. 

Vitamin A is considered an antioxidant, and this means it helps to keep free radicals from destroying healthy tissues. This means the nutrient helps to reduce cancer concerns that may affect your eyes and other parts of the body. 

Which Foods Contain Vitamin A?

You have likely heard that carrots are good for the eyes, and this is certainly true. Carrots and other orange and yellow colored fruits and vegetables like sweet potatoes, cantaloupe, squash, and bell peppers all contain beta-carotene. Beta-carotene is converted into vitamin A once it is absorbed by the body. It is fairly easy to meet your daily vitamin A requirements by eating a single food with beta-carotene. For example, one sweet potato contains over five times the vitamin A that you need in one day. 

You can also provide your body with vitamin A directly by eating animal products that contain the vitamin. Liver, eggs, cod fish, and some dairy products contain the nutrient. If you do not wish to eat these foods, then you can invest in a fish oil supplement. Cod liver oil is the best supplement to provide your body with vitamin A. The supplements also contain a good deal of omega-3 fatty acids. These fats offer an added benefit to the eyes by helping to reduce your macular degeneration risks.

Vitamin A is a great nutrient for the eyes. If you want to know more about how the benefits of the vitamin as well as the positive attributes of other nutrients, make sure to speak with your eye doctor or a vitamin provider (such as Cambridge Institute for Better Vision) about your diet.
