The Impact of Vitamin Deficiency on Vision and "Night Blindness"

When it comes to the impact of vitamin deficiency on vision and the development of "night blindness," the correct answer is vitamin A. Vitamin A plays a crucial role in maintaining good vision and preventing various eye conditions.

Vitamin A is essential for the proper functioning of the retina, which is the light-sensitive tissue at the back of the eye. It helps in the production of a pigment called rhodopsin, which is necessary for vision in low-light conditions. Without sufficient vitamin A, the production of rhodopsin is impaired, leading to a condition known as "night blindness" or nyctalopia. People with night blindness have difficulty seeing in dim light or at night [[1]].

Furthermore, vitamin A deficiency can also lead to a more severe condition called xerophthalmia. Xerophthalmia is a progressive eye disease characterized by dryness of the conjunctiva (the clear membrane covering the white part of the eye) and cornea (the transparent front part of the eye). If left untreated, xerophthalmia can cause corneal ulcers, scarring, and even blindness [[2]].

Therefore, the correct answer to the question is c) vitamin "A".
