Understanding Night Myopia While Driving

Night myopia, also known as "night blindness" or "twilight myopia," is a condition where individuals experience blurred vision and difficulty focusing on distant objects in low-light conditions, such as while driving at night. This phenomenon occurs because the eyes' lenses struggle to maintain the correct focus in dim lighting. The lack of adequate light causes the pupils to dilate, which increases spherical aberration and reduces the eyes' depth of field. Consequently, objects at a distance appear blurry, and drivers might have trouble seeing road signs, pedestrians, and other vehicles clearly.
