Vitamin A and Eyesight
Vitamin A plays an important role in preserving eyesight. It is necessary for the body to convert light into electrical signals, which are then transmitted to the brain. That’s why an early sign of vitamin A deficiency may be nyctalopia, often known as night blindness. This vitamin is the main part of rhodopsin, a pigment in the retina of the eye. Taking sufficient vitamin A can help you slow down the decline in eyesight, especially in aging people. [1]
