Which vitamin plays a crucial role in vision?

Vitamin A is essential for vision due to its role in the formation of rhodopsin, a pigment found in the retina that is critical for low-light and color vision. When light hits the retina, rhodopsin undergoes a chemical change that sends signals to the brain, allowing us to perceive images. Furthermore, vitamin A contributes to the maintenance of healthy vision by supporting the health of the cornea as well as the other eye structures. A deficiency in vitamin A can lead to night blindness and more severe vision issues, emphasizing its importance in visual health.

The other vitamins listed do have significant health benefits but are not primarily associated with vision. Vitamin C acts as an antioxidant and supports the immune system, while vitamin E also provides antioxidant protection and contributes to overall health, but neither is directly involved in the complex processes of vision. Vitamin B1, or thiamine, is vital for energy metabolism and nerve function but does not play a role in vision specifically.
