What Is Night Blindness?
Q: What Is Night Blindness?

A. People with night blindness (also called impaired dark adaptation) see poorly in the darkness but see normally in enough light. The condition does not actually involve true blindness, even at night. Symptoms include difficulty seeing when driving in the evening or at night, poor vision in reduced light, and feeling that the eyes take longer to “adjust” to seeing in the dark.

Visit a knowledgeable professional to find out whether your night blindness is caused by a deficiency of vitamin A or zinc and, if so, for a recommendation on the amounts and duration of treatment.
