Carrots are the vegetable most commonly known for helping improve eyesight. They are particularly rich in beta-carotene, a type of vitamin A that is essential for maintaining healthy vision. The body converts beta-carotene into vitamin A, which is crucial for the formation of rhodopsin, a pigment in the retina that helps the eyes perceive low-light conditions. Additionally, a diet rich in carrots and similar vegetables can help reduce the risk of age-related macular degeneration and other vision-related issues, making them a beneficial component of a balanced diet for eye health.
