Night blindness is the inability to see well in low light conditions and is a symptom of an underlying eye disorder rather than a condition itself. Common causes include untreated nearsightedness, glaucoma medications, cataracts, retinal diseases, and vitamin A deficiency. Treatment depends on the underlying cause but may involve changing eyeglass prescriptions, adjusting medications, or surgery to remove cataracts.
