Learn About the Science Behind Auto-Dimming Mirrors

Have you ever looked at your auto-dimming rearview mirror and thought, how does this feature work? If so, our team at Audi Calabasas in Calabasas, CA can tell you how. Auto-dimming mirrors are a common feature in automobiles and can help keep your visibility clear.

The Troxler Effect is a term that was coined by a major auto-dimming manufacturer known as Gentex. This happens when the headlights of the vehicle behind you cause you to get a blind spot, which can delay your reaction time. According to Gentex, a driver's reaction time can be delayed by up to 1.4 seconds because of the Troxler Effect. A vehicle can travel about 123 feet in that amount of time if it's moving at 60 mph.

Auto-dimming rearview mirrors have two sensors that are usually cameras or photodetectors. When these sensors detect light from the headlights of the vehicle behind, it will send an electrochromic gel that will become dark and block glare.
