You may have been told that carrots help you see better, but is this the truth? Optometrists will tell you that carrots can't actually improve your vision. However, they do contain significant quantities of beta-carotene, a vitamin that is very good for the health of your eyes and therefore consuming foods rich in beta-carotene is surely advised for maintaining eye health.
Beta-carotene is an orange pigment (carotenoid) that changes into vitamin A after it's digested in the human body. Vitamin A strengthens the surface of the eye (cornea) and has been shown to be preventative for various eye diseases such as macular degeneration. Vitamin A, an antioxidant compound, protects the surface of the eye to decrease the risk of eye 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 this important vitamin (which tends to be more common in underdeveloped countries) is known to cause night blindness, corneal ulcers and retinal damage which can lead to blindness.
Two forms of vitamin A exist, which depend upon the nutritional source from which they come. Vitamin A originating from an animal is called Retinol and can be found in foods such as beef, chicken liver, or dairy products. Vitamin A that is derived from produce comes in the form of ''provitamin A'' carotenoids, which convert to retinol after the food is absorbed. In addition to carrots, carotenoids can be found in colorful fruits and vegetables such as oranges, sweet potatoes, spinach, kale and cantaloupes.
There is no question that vitamin A is beneficial to your eyes and your total well being. Even though carrots themselves can't fix optical distortion which causes vision impairments, mother had it right when she advised ''eat your vegetables.''
