7. Carrots boost your night vision

Carrots contain beta-carotene, which the body uses to make vitamin A. Vitamin A helps the eyes convert light into a signal that can then be transferred to the brain. This allows people to see in conditions where there is low light. Furthermore, vitamin A is necessary to keep the cornea at the front of the eye healthy and strong. Severe vitamin A deficiency can destroy the cornea and lead to blindness in extreme cases. In regions where malnutrition and severe vitamin A deficiency are widespread, supplements of vitamin A and beta-carotene can improve night vision and overall eye health.

However, for those of us who already have relatively adequate levels of vitamin A from our diets, eating carrots won’t give us super-human vision. People with vitamin A deficiencies may be able to restore their night vision to normal levels by taking vitamin A and beta carotene supplements. However, most of us already get plenty of vitamin A. Furthermore, most eye problems are not linked to vitamin A deficiency and therefore cannot be cured with vitamin A supplements.
