Are carrots really good for eyesight? While optometrists admit that carrots are made up of large amounts of a vitamin that has proven to be very good for your eyes, eating large amounts of the healthy vegetable will not substitute for visual aids.
Beta-carotene is an orange pigment (carotenoid) that converts into vitamin A once absorbed in the human body. Vitamin A helps to protect the cornea, or surface of the eye, and has been shown to be preventative for various eye diseases such as corneal ulcers. Vitamin A, a group of antioxidant compounds, protects the surface of the eye to decrease the frequency of eye infections and other infectious diseases. Vitamin A is also known to be a successful treatment for dry eye syndrome as well as other eye disorders. A deficiency of vitamin A (which is exist more in poor and developing countries) is known to cause night blindness, corneal ulcers and retinal damage which can lead to total blindness.
Two forms of vitamin A exist, which relate to the nutritional source they come from. 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 obtained from produce comes in the form of ''provitamin A'' carotenoids, which are converted to retinol after the food is digested. In addition to carrots, carotenoids are ingested when eating colorful produce such as oranges, sweet potatoes, spinach, kale and cantaloupes.
It is proven that vitamin A contributes to the health of your eyes as well as your total health. Even though carrots won't fix corneal refraction which causes vision impairments, mother was right when she said ''finish your vegetables.''
