Does eating carrots help improve eyesight?

Good news for carrot lovers out there! Yes, eating carrots do help improve eyesight. Carrots have carotene, which is converted by the body to vitamin A. Vitamin A is essential for the production of visual purple --- a photochemical substance, of a purplish red color contained in the retina of human eyes and in the eyes of most animals, that is quickly bleached by light, passing through the colors, red, orange, and yellow and then disappearing. Visual Purple helps a person see in the dark.
Without vitamin A, a person could develop night blindness or poor vision at night or in dim light.
