We have all heard that carrots help you see better, but is it the truth? Optometrists know that carrots can't prevent you from needing eye glasses. However, they are rich in beta-carotene, a vitamin that is beneficial for the health of your eyes and therefore ingesting carrots and other beta-carotene rich foods is clearly recommended for proper eye health.
Beta-carotene is an orange colored pigment (carotenoid) that converts into vitamin A after it's digested in the human body. Vitamin A helps to guard the surface of the eye (cornea) and has been proven to be preventative for various eye diseases such as macular degeneration. Vitamin A, which is composed of a number of antioxidants, protects the surface of the eye to decrease the risk of eye infections as well as other infectious illnesses. Vitamin A is also known to be an effective solution for dry eye syndrome and other eye disorders. A lack of this important vitamin (which is exist more in poor and developing countries) is known to cause night blindness, corneal ulcers and retinal damage which can contribute to blindness.
There are two types 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, whole milk or cheese. Vitamin A that is obtained 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 produce particularly those that are bright orange or green in color.
There is no question that vitamin A is beneficial to your eyes as well as your overall well being. Even though carrots can't fix optical distortion which causes vision impairments, grandma had it right when she said ''eat your vegetables.''
