We have all been told that carrots improve your eyesight, but is it the truth? Eye doctors say that carrots can't save you from needing eye glasses. However, carrots do provide significant amounts of beta-carotene, a vitamin that is beneficial for your eye health and therefore eating carrots and other beta-carotene rich foods is definitely advised for ensuring eye health.
Beta-carotene is an orange colored pigment (carotenoid) that changes into vitamin A after it's absorbed in the body. Vitamin A helps to guard the surface of the eye (cornea) and has been determined to be preventative for various eye diseases such as macular degeneration. Vitamin A, which is composed of a number of antioxidants, guards the cornea to reduce the frequency of eye infections and other infectious diseases. Vitamin A has also shown to be an effective solution for dry eyes as well as other eye conditions. A lack of this important vitamin (which tends to exist more in underdeveloped countries) often causes night blindness, corneal ulcers and retinal damage which can contribute to blindness.
There are two variations of vitamin A, which relate to the food source from which they come. Vitamin A derived from an animal is called Retinol and can be found in foods 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 break down to retinol after the food is absorbed. In addition to carrots, carotenoids can be found in colorful produce particularly those that are bright orange or green in color.
There is no question that vitamin A is beneficial to your eyes as well as your total well being. Although carrots themselves won't correct optical distortion which causes near or far-sightedness, mother had it right when she advised ''finish your carrots.''
