Q: Answer-Which vitamin deficiency is most directly associated with night blindness in humans?

Night blindness, or difficulty seeing in low light conditions, is most directly associated with a deficiency of vitamin A. Vitamin A is essential for the formation of visual pigments in the retina, particularly rhodopsin, which is found in rod cells that function in dim light. Foods rich in vitamin A are such as liver, eggs, milk, and beta-carotenerich vegetables like carrots and spinach, help prevent this condition.
