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 in the retina that enables the eyes to see in low light conditions. It is a vital nutrient that helps maintain healthy vision and is particularly important for the function of rod cells, which are the photoreceptor cells responsible for night vision.

In addition to its role in vision, Vitamin A is involved in numerous other bodily functions, including immune function and skin health. The body can obtain Vitamin A from both animal sources, such as liver and fish, and plant sources, such as carrots and sweet potatoes, where it exists in the form of provitamin A carotenoids.

Specific deficiencies in Vitamin A can lead to serious visual impairments, such as night blindness or complete blindness in severe cases. This underscores the vitamin's importance in maintaining proper eyesight and overall eye health.
