Synopsis

Source of validity: Scientific
Rating (out of 5): 4

Carrots have a strong scientific basis for their association with eye health. This is primarily due to their high content of beta-carotene, a precursor to vitamin A, which is essential for maintaining normal vision. Vitamin A forms a component of rhodopsin, a protein in the eye that allows for vision in low-light conditions. Deficiency in vitamin A can lead to night blindness and, in severe cases, permanent blindness. Numerous studies and public health initiatives, particularly in developing countries, have shown that increasing dietary intake of vitamin A (including from beta-carotene-rich foods like carrots) reduces the prevalence of vitamin A deficiency and associated eye disorders.

However, while carrots are helpful in preventing vitamin A deficiency and its consequences, they do not improve vision in individuals who already have sufficient vitamin A levels. The idea that eating large quantities of carrots will drastically improve eyesight beyond normal levels is a myth, though historically popularized during World War II. In summary, the use of carrots to support the eyes is scientifically validated in the context of preventing deficiency, but the benefits do not extend to supernormal vision enhancement.
