If you've ever glanced in your rearview mirror while driving at night, only to be blinded by the glaring headlights of the vehicle behind you, you'll appreciate the function that auto-dimming mirrors, also called electrochromic mirrors, perform. Our service technicians at Porsche Monterey wanted to provide a quick explanation as to how auto-dimming mirrors work.
Auto-dimming mirrors use a process called electrochromism that darkens the mirror in order to prevent what's called the "Troxler Effect", experiencing a visual blind spot after staring at a light glare in the rearview mirror. Auto-dimming mirrors are outfitted with two sensors which prompts a darker gel contained within the mirror to restrict the amount of light that is reflected from a vehicle following your car.
The auto-dimming mirror serves as an important safety feature in most newer model vehicles. They're one of the many amenities you'll discover when you come in for a test drive.
