Are carrots good for vision? While eye doctors affirm that the orange root vegetables are made up of significant amounts of a beta-carotene which is known to be very good for one's eyes, carrots can not take the place of suitable corrective eye care.
Beta-carotene is a carotenoid, or orange pigment that converts into vitamin A after it's digested in the body. Vitamin A strengthens the cornea, or surface of the eye, and has been proven to be preventative for a number of eye diseases such as corneal ulcers. Vitamin A, a group of antioxidant compounds, protects the cornea to decrease the frequency of ocular infections as well as other infectious illnesses. Vitamin A has also shown to be an effective treatment for dry eyes as well as other eye disorders. A lack of vitamin A (which is exist more in underdeveloped countries) often causes night blindness, corneal ulcers and retinal damage which can contribute to total blindness.
Two variations of vitamin A exist, 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, whole milk or cheese. Vitamin A that is derived from fruits and vegetables exists in the form of ''provitamin A'' carotenoids, which break down to retinol after the nutrients are digested. In addition to carrots, carotenoids can be found in 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 as well as your overall health. Although carrots themselves won't correct optical distortion which causes near or far-sightedness, grandma was right when she said ''eat your carrots.''
