You may have been told that carrots improve night vision, but is it really true? Eye care professionals will tell you that the orange vegetable can't actually improve your eyesight. However, carrots are rich in beta-carotene, a vitamin that is very good for the health of your eyes and therefore eating foods rich in this vitamin is definitely a recommendation for proper eye health.
Beta-carotene is an orange pigment (carotenoid) that converts into vitamin A once digested in the body. Vitamin A helps to protect the cornea, or surface of the eye, and has been shown to be preventative for a number of eye diseases such as corneal ulcers. Vitamin A, an antioxidant compound, protects the cornea to reduce the frequency of eye infections and other infectious diseases. Vitamin A is also known to be a successful solution for dry eyes as well as other eye conditions. A deficiency of vitamin A (which is exist more in poor and developing countries) often causes night blindness, corneal ulcers and retinal damage which can contribute to total blindness.
Two variations of vitamin A exist, which depend upon the nutritional source from which they come. Retinol is vitamin A derived from an animal source such as beef, chicken liver, or dairy products. Vitamin A that is derived from fruits and vegetables comes in the form of ''provitamin A'' carotenoids, which convert to retinol after the nutrients are absorbed. In addition to carrots, carotenoids are ingested when eating colorful fruits and vegetables such as oranges, sweet potatoes, spinach, kale and cantaloupes.
It is proven that vitamin A is beneficial to your eyes as well as your total well being. Even though carrots themselves can't correct near or far-sightedness, grandma had it right when she said ''finish your vegetables.''
