Deficiency in Vitamin A can lead to what health issue?

Vitamin A is crucial for maintaining proper eye health, primarily because it plays a vital role in the production of rhodopsin, a pigment in the retina that is necessary for vision in low-light conditions. A deficiency in this vitamin can lead to several eye-related issues, with night blindness being one of the most common early symptoms. Over time, a severe deficiency can result in more serious conditions, such as xerophthalmia, which is a dryness of the conjunctiva and cornea, potentially leading to blindness if not addressed. This emphasizes the importance of adequate Vitamin A levels for maintaining not just vision, but overall eye health.

The other options, while they may involve issues that vitamins could influence, are not directly linked to Vitamin A deficiency in the same way eye health is. Bone health relates more to vitamins such as D and K, skin issues may arise from deficiencies in various vitamins but are more commonly associated with others, and reproductive health is influenced by a different set of nutrients. Therefore, eye deterioration is the most specific and direct consequence of Vitamin A deficiency.
