HEALTH GUIDE REFERENCE FROM A.D.A.M
Vitamin A, also known as retinol, is essential to the formation of visual purple in the retina, which allows vision in dim light. Beta carotene, the precursor to vitamin A found in vegetables, has antioxidant properties, meaning it protects cells from the toxic damage of oxidation.
