(Redirected from Night blindness)
Nyctalopia (Greek for Night blindness) is a disease of the human eyes.The eyes of people who are night-blind cannot adapt to situations where there is relatively little light; as a result, they have trouble seeing in such situations.
There are a number of conditions that can cause this; most commonly:
- lack or deficiency of Vitamin A
- Several genetic conditions, most notably retinitis pigmentosa
- Wounds of the eye
