What does anti-glare for car rearview mirrors mean?

Anti-glare for car rearview mirrors refers to the use of special mirror lenses in the exterior rearview mirrors that prevent the dazzling strong light from the rear vehicle from reflecting into the driver's eyes. With anti-glare rearview mirrors, the glaring headlights of vehicles behind at night will become dimmer and softer; when there are no glaring lights from behind, the mirror reflection effect instantly returns to normal, ensuring stable and clear rear visibility and improving nighttime driving safety. The principle of automatic anti-glare rearview mirrors: they have two photodiodes, one installed on the front of the rearview mirror and one on the back, which receive light from the front and rear of the car respectively. When the headlights of a rear vehicle shine on the interior rearview mirror, the signals from the two photodiodes can determine that the light from behind is stronger than that from the front. The electronic controller then applies voltage to the ionization layer on the rearview mirror surface, darkening its color. The strong light from behind is largely absorbed by the mirror surface, and the remaining light reflected into the driver's eyes becomes softer.
As a driver who frequently drives at night, I particularly value anti-glare rearview mirrors. They prevent the glare from headlights of vehicles behind me from reflecting too brightly on the mirror, which could impair my vision of the road ahead. With this feature, nighttime driving becomes much safer because when the light from the rear is too strong, the mirror reduces the reflection through an automatic or manually adjusted mechanism, maintaining clear visibility and reducing fatigue and accident risks. Manual anti-glare mirrors typically require you to flip a small switch to change the angle—simple and practical. The automatic version is more advanced, using sensors to detect bright light and darken automatically, making it convenient and hassle-free. I recommend everyone learn how to use this feature, especially on highways or unfamiliar roads, as it can make the entire driving experience more secure and reduce accidents. Of course, regular maintenance shouldn’t be overlooked—a dirty mirror can affect its effectiveness, so it’s important to clean it periodically.
