Preserving Better Night Vision
Night vision plays an important role in recognizing objects and movement in low-light conditions. Bright reflections can temporarily make darker areas harder to see clearly.
After looking toward an intense light, the driver may need time to regain comfortable vision in the surrounding darkness. Even a brief disruption can feel unsettling when traveling at night.
Using the rearview mirror’s glare-reducing setting helps limit the intensity of light coming from behind. This supports a smoother transition between checking the mirror and returning attention to the road ahead.
Better visual comfort may make it easier to notice changing conditions. Pedestrians, road hazards, traffic movement, and other important details can be easier to monitor when the driver’s eyes are not repeatedly overwhelmed by reflected headlights.
