Synopsis

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

Vitamin A (as vitamin A acetate) is scientifically validated as essential for normal vision. The most well-established role of vitamin A in eyesight is its involvement in the formation of rhodopsin, a photopigment in the retina that is necessary for low-light (scotopic) vision. Deficiency in vitamin A leads to night blindness and, if unresolved, can progress to xerophthalmia, a severe eye disorder that may result in permanent blindness. Numerous clinical and epidemiological studies have demonstrated that vitamin A supplementation can prevent and treat these deficiency-related ocular conditions, particularly in populations where dietary intake of vitamin A is insufficient. The World Health Organization recommends vitamin A supplementation to reduce the risk of blindness in children in developing countries. However, for individuals with normal vitamin A status, additional supplementation does not improve vision or prevent age-related visual loss. The use of vitamin A for poor eyesight is thus justified when poor vision is due to deficiency but not for refractive errors or other non-deficiency causes. The scientific evidence supporting vitamin A’s role in the prevention and treatment of deficiency-related visual impairment is strong, and its use is included in public health guidelines in areas at risk.
