Can carrots really improve your vision? While optometrists admit that carrots contain significant quantities of a beta-carotene which is known to be beneficial for your eyes, ingesting a lot of the healthy vegetable will not eliminate your need for glasses or contact lenses.
Beta-carotene is an orange colored pigment (carotenoid) that converts into vitamin A after it's absorbed in the body. Vitamin A guards the surface of the eye (cornea) and has been shown to prevent various eye diseases such as corneal ulcers. Vitamin A, which is composed of a number of antioxidants, guards the surface of the eye to reduce the risk of eye infections as well as other infectious illnesses. Vitamin A is also known to be a successful solution for dry eyes as well as other eye disorders. A deficiency of this important vitamin (which is exist more in underdeveloped countries) often causes night blindness, corneal ulcers and retinal damage which can contribute to total blindness.
There are two forms of vitamin A, 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, liver, whole milk or cheese. Vitamin A that is fruit and vegetable-derived exists in the form of ''provitamin A'' carotenoids, which break down to retinol after the nutrients are absorbed. In addition to carrots, carotenoids can be found in colorful produce such as oranges, sweet potatoes, spinach, kale and cantaloupes.
It is proven that vitamin A contributes to the health of your eyes and your overall well being. Although carrots won't correct optical distortion which causes near or far-sightedness, grandma was right when she said ''finish your carrots.''
