Night blindness, or nyctalopia, is a vision condition that makes it difficult to see in low light or darkness. It is not a disease itself but a symptom of various underlying issues, such as vitamin A deficiency, cataracts, or retinal disorders. People with night blindness may struggle to adjust their vision when moving from bright to dim environments. This condition can affect daily activities, such as driving at night or navigating in poorly lit areas. Treatment often focuses on addressing the underlying cause, which may include dietary changes, surgery, or the use of corrective lenses. Regular eye exams can help detect and manage night blindness effectively.
