We have all heard that carrots improve night vision, but is this really true? Eye doctors know that carrots can't save you from needing eye glasses. However, carrots are rich in beta-carotene, a vitamin that is very good for the health of your eyes and therefore ingesting foods rich in this vitamin is definitely a recommendation for maintaining eye health.
Beta-carotene is a carotenoid, or orange pigment that converts into vitamin A after it's absorbed 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, guards the cornea to reduce the frequency of eye infections and other infectious illnesses. Vitamin A has also shown to be a successful solution for dry eyes and other eye conditions. A lack of this important vitamin (which is exist more in underdeveloped countries) often causes night blindness, corneal ulcers and retinal damage which can lead to complete blindness.
There are two variations of vitamin A, which depend upon the nutritional source from which they come. Vitamin A derived from an animal is called Retinol and can be obtained from foods such as beef, liver, or dairy products. Vitamin A that is fruit and vegetable-derived exists 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 produce particularly those that are bright orange or green in color.
There is no doubt that through most forms, vitamin A is beneficial to your eyes as well as your overall well being. Even though carrots themselves can't correct near or far-sightedness, mother was right when she advised ''finish your vegetables.''
