Vitamin A is primarily associated with vision health due to its crucial role in the functioning of the retina and overall eye health. This vitamin is essential for the synthesis of rhodopsin, a pigment found in the retina that allows the eye to see in low-light conditions. Without adequate Vitamin A, individuals may experience night blindness and other vision problems.

Additionally, Vitamin A supports the maintenance of healthy tissues in the eyes, contributing to the prevention of various eye disorders. Its antioxidant properties also help protect the eyes from damage caused by free radicals, further emphasizing its importance in maintaining vision health.

The other vitamins mentioned, while beneficial to overall health, do not have the same direct association with vision. Vitamin C is known for its role in immune function and skin health, Vitamin D is vital for bone health and immune system regulation, and Vitamin E is primarily recognized for its antioxidant properties in protecting body tissues. However, none of these vitamins specifically target visual health to the extent that Vitamin A does.
