The Facts About the Vision Benefits of Eating Carrots



We have all been told that carrots improve your vision, but is it really true? Eye doctors will tell you that regardless of how many carrots you eat, they can't prevent you from needing eye glasses. However, they do contain substantial quantities of beta-carotene, a vitamin that is very good for your eye health and therefore eating foods rich in this vitamin is surely advised for maintaining eye health.

Beta-carotene is a carotenoid, or orange pigment that changes into vitamin A after it's absorbed in the body. Vitamin A strengthens the cornea, or surface of the eye, and has been determined to be preventative for various eye diseases such as corneal ulcers. Vitamin A, which is composed of a number of antioxidants, guards the surface of the eye to decrease the risk of ocular infections as well as other infectious illnesses. Vitamin A is also known to be a successful solution for dry eye syndrome and other eye conditions. A deficiency of this important vitamin (which is be more common in underdeveloped countries) often causes night blindness, corneal ulcers and retinal damage which can lead to total blindness.

Two types of vitamin A exist, which relate to the food source they come from. Retinol is vitamin A that comes from an animal source such as beef, chicken liver, whole milk or cheese. Vitamin A that is derived from produce exists in the form of ''provitamin A'' carotenoids, which convert to retinol after the food is digested. In addition to carrots, carotenoids can be found in colorful fruits and vegetables such as oranges, sweet potatoes, spinach, kale and cantaloupes.

It is proven that vitamin A contributes to the health of your eyes as well as your total health. Although carrots won't fix corneal refraction which causes near or far-sightedness, mother had it right when she said ''eat your carrots.''
