Do Carrots Really Improve your Eyesight?

Are carrots beneficial for vision? While eye care professionals admit that carrots are made up of large quantities of a vitamin which is known to be very good for one's eyes, ingesting large amounts of the healthy vegetable will not substitute for glasses or contact lenses.

Beta-carotene is a carotenoid, or orange pigment that changes into vitamin A after it's absorbed in the body. Vitamin A protects the cornea, or surface of the eye, and has been proven to be preventative for certain eye diseases such as corneal ulcers. Vitamin A, which is composed of a number of antioxidants, guards the surface of the eye to reduce the frequency of eye infections as well as other infectious illnesses. Vitamin A has also shown to be a successful treatment for dry eye syndrome and other eye conditions. A deficiency of this important vitamin (which is exist more in underdeveloped countries) is known to cause night blindness, corneal ulcers and retinal damage which can contribute to blindness.

There are two forms of vitamin A, which depend upon the nutritional source they come from. Retinol is vitamin A derived from an animal source such as beef, chicken liver, or dairy products. Vitamin A that is derived from produce exists in the form of ''provitamin A'' carotenoids, which are converted to retinol after the food is absorbed. In addition to carrots, carotenoids are ingested when eating colorful produce particularly those that are bright orange or green in color.

It is proven that through most forms, vitamin A is beneficial to your eyes and your overall health. Although carrots won't correct vision impairments, grandma had it right when she said ''finish your carrots.''
