Synopsis

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

Vitamin A (including its form, vitamin A acetate) is scientifically validated as essential for supporting the health and function of the eyes. Its most well-established role is in the visual cycle, particularly for vision in low-light conditions. Vitamin A is a crucial component of rhodopsin, a protein in the retina that absorbs light. Deficiency in vitamin A can result in night blindness and, if severe and prolonged, can lead to more serious ocular issues like xerophthalmia (dryness of the conjunctiva and cornea) and even irreversible blindness. The World Health Organization recognizes vitamin A supplementation as a key intervention in the prevention of blindness in at-risk populations, particularly children in developing countries.

Numerous clinical and epidemiological studies have confirmed the relationship between vitamin A status and eye health. Supplementation has been shown to reverse early signs of deficiency-related eye symptoms and reduce the risk of blindness in deficient populations. However, for individuals with adequate vitamin A intake, additional supplementation does not further improve vision. Thus, vitamin A is critical for normal eye function, and its use to support the eye body system is backed by strong scientific evidence.
