Answer 1

Vitamin A deficiency can cause night blindness, affecting the ability to see well in dim light conditions.

Step-by-step explanation:

If a lag occurs before the eye can see again after a flash of bright light at night, it may be a symptom of vitamin A deficiency. Vitamin A plays a crucial role in maintaining good vision, particularly in low light conditions. A deficiency in vitamin A can lead to night blindness, which is the inability to see well in dim light. Night blindness can occur due to impaired function of the rod cells in the retina that are responsible for dim light vision.
