Which vitamin is essential for maintaining healthy vision?

• A. Vitamin B12
• B. Vitamin A
• C. Vitamin C
• D. Vitamin D

Answer: (B)

Vitamin A is crucial for maintaining healthy vision, primarily because it plays a vital role in the formation of rhodopsin, a pigment in the retina that allows the eyes to see in low light conditions. It also supports the overall health of the cornea, which is essential for clear vision. Deficiency in Vitamin A can lead to night blindness and, in severe cases, complete blindness. In addition to its role in vision, Vitamin A contributes to the overall health of the immune system and promotes healthy skin. This vitamin can be found in foods such as carrots, sweet potatoes, spinach, and liver. Other vitamins, while beneficial for various bodily functions, do not play the same pivotal role in vision as Vitamin A does. For instance, Vitamin B12 is essential for nerve health and the production of red blood cells, Vitamin C is important for collagen synthesis and overall immune function, and Vitamin D is primarily involved in calcium metabolism and bone health.
