Are carrots really good for your eyesight?
To ease kids’ suspicion of vegetables, parents often feed them the adage that carrots will spare them from corrective vision care. But is there any truth to the commonly held belief that carrots are good for your eyes?
Well, yes and no. Carrots won’t improve your visual acuity if you have less than perfect vision. For example, a diet of carrots won’t give a blind person 20/20 vision. But the vitamins found in the vegetable can help promote overall eye health. Carrots contain beta-carotene, a substance that the body converts to vitamin A, an important nutrient for eye health.
Carrots are rich in beta-carotene, a carotenoid pigment found in many orange fruits and vegetables. Beta-carotene is an important precursor for vitamin A. An extreme lack of vitamin A can cause blindness. In fact, in the developing world, vitamin A deficiency is the leading cause of blindness.
Lack of vitamin A can also lead to xerophthalmia, a condition in which the eyes can no longer produce tears, dryness in the eyes, swollen eyelids and corneal ulcers. Vitamin A can prevent the formation of cataracts and macular degeneration, the world’s leading cause of blindness.
