What is a significant symptom of Vitamin A Deficiency?

Night blindness is a significant symptom of Vitamin A deficiency. This condition occurs because Vitamin A is essential for the formation of rhodopsin, a light-sensitive protein in the retina that is crucial for vision in low-light conditions. When there is a deficiency, the ability to see in dim light is impaired, leading to night blindness. This symptom is often one of the earliest indicators of inadequate Vitamin A levels in the body.

In contrast, while angular stomatitis, photophobia, and scaly skin can be related to various nutritional deficiencies or other medical conditions, they are not specifically indicative of Vitamin A deficiency in the same way that night blindness is recognized. Therefore, night blindness stands out as a hallmark symptom directly associated with a lack of this essential vitamin.
