An auto-dimming rearview mirror is a nifty piece of safety technology. It dims automatically when your vehicle comes into contact with glare from high beams or from ambient bright light. How does it work? Our Land Rover Westside team serving Cleveland has your fast, fun answer.
Introducing Electrochromic Technology
An auto-dimming rearview mirror works by containing electrochromic materials. These are materials that change in color or opacity when they meet with an electrical charge. After the electrical charge goes away, so does the mirror's opacity.
How it Works
Glass coated in material that conducts electricity is at the heart of an auto-dimming mirror. These units also contain electrochromic gel, light sensors and a special controller. Electricity passes over the coated mirrors after the mirror's sensors detect glare.
The electrochromic gel covering the mirror then darkens. As long as the mirror's sensors detect glare, it continues to emit an electrical charge, keeping the electrochromic gel opaque. The gel's opacity vanishes when the rearview mirror's sensors no longer detect bright light.
