You may have been told that carrots help you see better, but is it the truth? Optometrists know that carrots can't actually improve your vision. However, carrots do provide substantial amounts of beta-carotene, a vitamin that is beneficial for the health of your eyes and therefore ingesting foods rich in beta-carotene is surely recommended for maintaining eye health.
Beta-carotene is an orange colored pigment (carotenoid) that converts into vitamin A once absorbed in the body. Vitamin A helps to guard the surface of the eye (cornea) and has been determined to prevent certain eye diseases such as corneal ulcers. Vitamin A, which is composed of a number of antioxidants, protects the surface of the eye to reduce the risk of ocular infections as well as other infectious illnesses. Vitamin A has also shown to be an effective treatment for dry eye syndrome as well as other eye disorders. A lack of vitamin A (which is exist more in underdeveloped countries) is known to cause night blindness, corneal ulcers and retinal damage which can contribute to blindness.
There are two forms of vitamin A, which relate to the food source they come from. 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 convert to retinol after the nutrients are digested. In addition to carrots, carotenoids are ingested when eating colorful fruits and vegetables particularly those that are bright orange or green in color.
It is proven that through most forms, vitamin A contributes to the health of your eyes and your total health. Even though carrots won't correct optical distortion which causes vision impairments, mother had it right when she said ''finish your carrots.''
