Many drivers don’t realize their car includes a simple feature designed to make nighttime driving more comfortable and less stressful. The small lever or button on the rearview mirror is easy to overlook, yet it serves an important purpose. When switched to the night or anti-glare setting, the mirror tilts slightly, reducing the brightness of headlights from vehicles behind you.

This gentle adjustment softens harsh reflections without blocking your view of the road. Using it can make a noticeable difference during evening or early-morning trips. Bright lights in the mirror can strain your eyes and make it harder to stay focused. By switching the mirror to its dimmed setting, you help protect your eyes and maintain clearer night vision.

This improvement allows you to see road markings, traffic changes, and obstacles more easily. It also reduces the discomfort that comes from long periods of driving in the dark. The feature becomes even more effective when combined with simple habits that support visibility. Clean mirrors and windows prevent scattered light, and properly aligned headlights make driving safer for you and others. Together, these small steps can help create a calmer, clearer driving environment.

What makes this feature especially useful is how quick and effortless it is to use. It requires no tools and only a moment of your time, yet it can lower eye fatigue and enhance your overall driving experience. Adding this adjustment to your nighttime routine can support better awareness, sharper focus, and a more relaxed ride — no matter how bright the headlights are behind you.
