We have all been told that carrots improve your vision, but is it the truth? Eye doctors will tell you that the orange vegetable can't actually improve your eyesight. However, they do contain substantial amounts of beta-carotene, a vitamin that is beneficial for the health of your eyes and therefore ingesting carrots and other beta-carotene rich foods is surely recommended for maintaining eye health.
Beta-carotene is an orange pigment (carotenoid) that changes into vitamin A after it's digested in the human body. Vitamin A helps to protect the cornea, or surface of the eye, and has been proven to be preventative for various eye diseases such as macular degeneration. Vitamin A, an antioxidant compound, guards the cornea to decrease the risk of eye infections and other infectious diseases. Vitamin A is also known to be a successful solution for dry eyes and other eye disorders. A lack of this important vitamin (which is exist more in poor and developing countries) often causes night blindness, corneal ulcers and retinal damage which can lead to blindness.
Two forms of vitamin A exist, which relate to the food source they come from. Retinol is vitamin A that comes from an animal origin such as beef, chicken liver, or dairy products. Vitamin A that is fruit and vegetable-derived comes in the form of ''provitamin A'' carotenoids, which convert to retinol after the food is 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 doubt that through most forms, vitamin A contributes to the health of your eyes as well as your overall well being. Although carrots can't fix near or far-sightedness, mother had it right when she advised ''finish your vegetables.''
