Auto-dimming mirrors use electrochromic technology. Electrochromic materials change in color or opacity when exposed to electricity. How does this work in a rearview mirror? Our Fargo team at your local Valley Imports Mitsubishi demystifies the auto-dimming rearview mirror.
Auto-Dimming Rearview Mirrors 101
Auto-dimming rearview mirrors have a special electrically-conductive coating. They also contain a darkening gel, photo sensors and a control unit. When the mirror's photo sensors detect light from the front or the back, electrical current passes through the mirror's darkening gel.
As more current passes through the gel, the gel darkens, causing the rearview mirror to dim. The mirror remains dark so long as glare remains present.
Benefits of Auto-Dimming Rearview Mirrors
Because of their automation, auto-dimming rearview mirrors add another ingredient of safety to your driving experience. You don't have to adjust them manually, taking your eyes off the road or your hands off of the steering wheel. Most auto-dimming rearview mirrors can be turned off and on as needed.
