Carotene, particularly beta-carotene, has a well-established scientific basis for its use in supporting eye health. Beta-carotene is a provitamin A carotenoid, meaning the body converts it into vitamin A as needed. Vitamin A is essential for normal vision, particularly for forming rhodopsin, a pigment in the retina that is necessary for low-light and color vision. Deficiency in vitamin A can lead to night blindness and more severe eye disorders such as xerophthalmia. Multiple clinical studies and large-scale trials, most notably the Age-Related Eye Disease Study (AREDS and AREDS2), have demonstrated that supplementation with beta-carotene (in combination with other antioxidants) can slow the progression of age-related macular degeneration (AMD) in some people. However, these benefits are primarily seen in populations at risk of deficiency or with existing eye conditions; routine supplementation is not recommended for everyone, especially smokers, as high-dose beta-carotene has been associated with increased lung cancer risk in this group. Overall, the use of carotene for eye health is supported by strong scientific evidence, particularly relating to vitamin A deficiency and prevention of certain degenerative eye diseases.
