Which vitamin is primarily responsible for vision?

Vitamin A is primarily responsible for vision due to its crucial role in the formation of rhodopsin, a protein found in the retina that is essential for low-light and color vision. This vitamin is converted by the body into retinol, which is necessary for the maintenance of healthy vision. Without adequate Vitamin A, individuals can experience vision problems, including night blindness, as it impairs the eyes' ability to adjust to varying light levels.

In addition, Vitamin A is vital for the health and functioning of the cornea, the outer layer of the eye, and it supports overall eye health. Therefore, Vitamin A is essential to maintaining good vision, highlighting its importance in any nutritional care or support context related to ocular health.
