We here at Schrier Automotive want you to know all there is to know when it comes to owning a vehicle. Today, we would like to explain how auto-dimming rearview mirrors work.

Not only can bright lights in the rearview mirror blind you, but even when the vehicle turns off you are sometimes left with a blind spot from it called the "Troxler Effect." This is where an auto-dimming mirror comes in.

This type of mirror darkens itself with the electrochromism process when its built-in sensor, either a camera or a photodiode-based photodetector senses glaring bright lights. The sensor and a microprocessor work together, sending a charge that causes electrochromic gel between the glass layers of the mirror to reduce oxidation, so it darkens. Since the 1980s, this technology has become a standard feature in many vehicles.

Come see us here at Schrier Automotive to take a test drive today!
