Eye Doctor Insight: Carrots and Eyesight

Are carrots good for vision? While eye doctors admit that carrots are made up of significant quantities of a vitamin which is known to be very good for one's eyes, eating large amounts of carrots will not eliminate your need for corrective eye wear.

Beta-carotene is a carotenoid, or orange pigment that converts into vitamin A once digested in the human body. Vitamin A helps to guard the cornea, or surface of the eye, and has been proven to be preventative for certain eye diseases such as macular degeneration. Vitamin A, which is composed of a number of antioxidants, guards the surface of the eye to reduce the risk of eye infections and other infectious illnesses. Vitamin A is also known to be a successful treatment for dry eyes as well as other eye disorders. A lack of this important vitamin (which tends to exist more in poor and developing countries) is known to cause night blindness, corneal ulcers and retinal damage which can contribute to total blindness.

There are two variations of vitamin A, which depend upon the nutritional source they come from. Retinol is vitamin A that comes from an animal source such as beef, chicken liver, or dairy products. Vitamin A that is obtained from fruits and vegetables exists in the form of ''provitamin A'' carotenoids, which are converted to retinol after the nutrients are absorbed. In addition to carrots, carotenoids are ingested when eating colorful fruits and vegetables such as oranges, sweet potatoes, spinach, kale and cantaloupes.

There is no question that through most forms, vitamin A is beneficial to your eyes and your total health. Even though carrots can't correct optical distortion which causes near or far-sightedness, grandma had it right when she advised ''eat your vegetables.''
