Synopsis

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

Vitamin A (retinyl acetate) has strong scientific validation for its use in supporting and treating certain eye problems, particularly those related to vitamin A deficiency. Vitamin A is essential for the formation of rhodopsin, a photopigment in the retina that is critical for low-light (scotopic) vision. Deficiency in vitamin A leads to night blindness and, if severe and prolonged, can cause xerophthalmia, a condition characterized by dryness of the conjunctiva and cornea, potentially leading to blindness. Multiple clinical studies and public health interventions have documented that vitamin A supplementation can reverse night blindness and prevent progression to more severe eye disease, especially in populations at risk of deficiency (such as children in developing countries). The World Health Organization and other authoritative health bodies recommend vitamin A supplementation as a key strategy to reduce blindness and mortality related to deficiency states. However, vitamin A supplementation does not treat other common eye conditions such as age-related macular degeneration or myopia in well-nourished populations. In summary, the use of vitamin A (retinyl acetate) for preventing and treating deficiency-related eye diseases is thoroughly supported by scientific evidence, making it an essential micronutrient for ocular health where deficiency is present.
