What is night blindness?

Night blindness (nyctalopia) is the inability to see well at night or in poor light. It is not a disease in itself, but rather a symptom of an underlying problem, usually a retina problem. It is common for patients who are myopic to have some difficulties with night vision, but this is not due to retinal disease, but rather to optical issues.
