Synopsis

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

Vitamin A, particularly in the form of retinol acetate, has robust scientific validation for its role in supporting the eyes and vision. Vitamin A is an essential component of rhodopsin, a protein in the retina that absorbs light and is necessary for both low-light (scotopic) and color vision. Deficiency in vitamin A is a well-established cause of night blindness and, in more severe cases, can lead to xerophthalmia, a spectrum of ocular diseases including dryness of the conjunctiva and cornea, and ultimately, irreversible blindness if untreated. Numerous studies, including randomized controlled trials and epidemiological surveys, have consistently demonstrated that vitamin A supplementation can prevent and treat ocular symptoms related to deficiency, particularly in populations at risk for malnutrition. The World Health Organization recommends vitamin A supplementation as a public health intervention to reduce the risk of blindness and mortality in children in areas with high rates of deficiency. The link between vitamin A and eye health is one of the most clear-cut and widely accepted relationships in nutrition science, with decades of research supporting its critical function in maintaining normal vision and overall ocular health.
