What Causes Night Blindness (Nyctalopia)?

Nyctalopia is a condition that occurs when an individual has difficulty seeing in poor lighting conditions or during the night. Rather than being a disease on its own, the condition is typically considered a symptom of other underlying disorders. The treatment for night blindness varies depending on its cause. Some treatments are simple, like new medications, vitamin supplements, or a new glasses prescription. If the condition is caused by cataracts or certain other issues, it may necessitate surgery. In rare cases, night blindness can be part of a more serious eye condition that will lead to loss of daytime vision as well.
