Which vitamin is associated with vision and is found in carrots and leafy greens?

• A. Vitamin C
• B. Vitamin E
• C. Vitamin A
• D. Vitamin D

Answer: (C)

Vitamin A is the nutrient tied to vision because it is needed to form rhodopsin, the light-detecting pigment in the retina that lets you see in dim light. Carrots and leafy greens are rich in beta-carotene, a plant-based precursor to vitamin A. When you eat them, your body converts beta-carotene into retinol, the active form of vitamin A, which supports the retina’s ability to respond to light and helps maintain the eye’s surface. A deficiency can lead to night blindness and dry eyes. The other vitamins have different roles—C supports immune function and collagen, E acts as an antioxidant, and D is important for calcium and bone health—so vitamin A is the one most closely associated with vision.
