Night Blindness: Causes, Symptoms, & Treatment

Night blindness is also known as nyctalopia, is a condition in which your eyes are unable to adapt to the low-light situation such as at night. Night blindness is not a disease itself but is a result of an existing eye disorder. Night blindness only affects a person’s ability to see in dim light. It does not cause complete blindness but only a problem which prevents your eyes from getting settled in the dark environment.
