What is the condition called when one is unable to see well at night?

The condition where a person has difficulty seeing well at night is known as night blindness. Night blindness, or nyctalopia, can occur due to various factors, including deficiencies in vitamin A, certain eye diseases, or as a side effect of medications. Individuals with night blindness may struggle to see clearly in low-light conditions, making it challenging to drive safely after dark or in dimly lit environments.

In contrast, color blindness refers to the inability to perceive colors correctly, depth perception relates to the ability to judge distances between objects, and tunnel vision describes a loss of peripheral vision while maintaining central vision. Each of these conditions affects vision differently, but none specifically address the challenges associated with low-light visibility as night blindness does.
