What is one of the effects of Vitamin A deficiency?

Vitamin A deficiency is known to lead to night blindness, which is a significant health concern. This condition occurs because Vitamin A is essential for the production of rhodopsin, a pigment found in the retina that is crucial for low-light vision. Without adequate Vitamin A, the eyes cannot adjust correctly when moving from a well-lit area to a dimly lit one, resulting in difficulty seeing in low light or darkness.

While night blindness is a common symptom of Vitamin A deficiency, individuals who are deficient may also experience other health issues, such as dry eyes or more serious eye conditions. Although the other options mention potential health effects or outcomes, night blindness specifically highlights a direct consequence of insufficient Vitamin A intake.
