Synopsis

Source of validity: Traditional
Rating (out of 5): 2

Carrots have been traditionally associated with eye health, largely due to their high content of beta-carotene, a precursor to vitamin A. In many cultures, the belief that eating carrots can improve vision or support eye health is well established, and this practice has been passed down through generations. While vitamin A deficiency can indeed cause vision problems, including night blindness and, in severe cases, more serious eye conditions, the direct application of carrots or their use specifically for acute symptoms like red or itching eyes is less well supported by scientific evidence. The association between carrots and general eye health is rooted in the historical observation that carrots are a good dietary source of vitamin A, which is essential for maintaining the health of the cornea and conjunctival membranes. However, for conditions such as red or itching eyes, which are typically caused by allergies, infections, or irritants, there is limited scientific evidence to suggest that carrot consumption or topical application directly alleviates these symptoms. Thus, while the traditional use is based on the important role of vitamin A in eye health, it does not specifically address acute eye discomfort, and the evidence for this particular use remains weak and largely anecdotal.
