Which vitamin is known for its role in vision?

Vitamin A is well-known for its crucial role in vision, particularly in the functioning of the retina in the eyes. It is a component of rhodopsin, a protein in the eyes that allows us to see in low-light conditions. When light hits the retina, rhodopsin undergoes a biochemical change that initiates the process of vision. A deficiency in Vitamin A can lead to vision problems, including night blindness, where one has difficulty seeing in dim light.

Moreover, Vitamin A is also involved in maintaining the health of the cornea and the overall integrity of the eye, which supports clear vision. This vitamin is traditionally found in two main forms: retinol, which is found in animal products, and carotenoids, which are found in colorful fruits and vegetables. This connection between Vitamin A and eye health solidifies its importance in maintaining good vision and underscores why it is the correct answer for this question.
