It does seem likely that carrots help your eyesight, so it’s not a myth! Carrots, and other colorful vegetables, tend to have a lot of vitamin A, and vitamin A helps the retina to stay healthy and working well. This is because it helps to generate rhodopsin, which is a light-sensing molecule located in the retina. Developing a deficiency of vitamin A can actually lead to night blindness!
Unlike the myth about chocolate causing acne, carrots actually do help your eyesight because they contain a lot of vitamin A, which is important for the health of your retinas.
