Nyctalopia, commonly known as night blindness, is a visual impairment that makes it difficult to see in low-light conditions. People with this condition may struggle to adjust their vision when transitioning from bright to dim environments, affecting their ability to drive at night or navigate in poorly lit areas. This condition can result from various factors, including deficiencies in vitamin A, certain eye diseases like retinitis pigmentosa, or damage to the rods in the retina. Treatment often focuses on addressing the underlying cause, such as improving nutrition or managing specific eye conditions.
