From Wikipedia, a free encyclopedia written in simple English for easy reading.
Night blindness is a disease of the human eyes. People who are night blind are unable to see in the dark or have great difficulty to see in the dark. Sometimes the disease is there since birth, and sometimes it is caused in life by external factors (like for example a wounding of the eyes, or a diseases of the retina).
Doctors call the disease Nyctalopia.
