Which nutrient is crucial for maintaining healthy vision?

• A. Vitamin C
• B. Fiber
• C. Vitamin A
• D. Calcium

Answer: (C)

The nutrient that is crucial for maintaining healthy vision is Vitamin A. This vitamin plays a vital role in the formation of rhodopsin, a protein in the eyes that is necessary for seeing in low light conditions. Additionally, Vitamin A contributes to the overall health of the retina, which is essential for clear vision. It helps prevent night blindness and is important for overall eye health.

Other nutrients like Vitamin C and calcium also support various bodily functions and health, but they do not directly influence vision in the same critical way that Vitamin A does. Fiber, while important for digestive health, does not play a direct role in maintaining eye health. Thus, Vitamin A stands out as the key nutrient for healthy vision.
