Which vitamin is essential for vision?

Vitamin A is essential for vision because it plays a critical role in the formation of rhodopsin, a pigment found in the retina that is responsible for the perception of light. This vitamin is crucial for maintaining healthy vision, particularly in low-light conditions. A deficiency in Vitamin A can lead to night blindness and, in severe cases, complete loss of vision.

Additionally, Vitamin A contributes to the overall health of the eyes, helping to protect the surface of the cornea. It also supports the function of cells in the retina that process visual signals. This is why ensuring adequate intake of Vitamin A is vital for maintaining good eyesight throughout life.
