Night blindness, which is also known as nyctalopia. It is a condition where the eye is not able to adapt to low-light conditions, such as at nighttime. The cause of night blindness is an underlying ocular problem; it is not a separate medical condition.
The eye has to adjust to low light. Night blindness does not result in total blindness, even if it negatively impacts a person’s vision in low light. It may cause issues seeing road signals while driving at night. Additionally, the eye may take longer than usual to adjust when moving from bright to dark settings.
