Night-blindness result from a deficiency of

Night blindness results from a deficiency of Vitamin A. Vitamin A is essential for good vision, especially in low light conditions. It is required for the proper functioning of the retina, the part of the eye that senses light and helps us see. When the body does not get enough Vitamin A, the retina cannot function properly, leading to night blindness. Night blindness is a condition where the affected person has difficulty seeing in low light conditions, such as at dusk or in dimly lit rooms. It can also lead to other vision problems, such as a decreased ability to see contrasting colors or an increased sensitivity to glare. Vitamin E, Vitamin K, and Vitamin C are important for other bodily functions, but not for vision.
