The Process Behind Auto-Dimming Mirrors

Drivers of modern vehicles are likely to be familiar with the concept of an auto-dimming mirror. These mirrors self-adjust from a regular, reflective surface to a darker color. The impetus for the adjustment is a flash of light from a vehicle's head beam. This technology actually has an interesting process behind it. Learn how electrochromism plays a role in auto-dimming.

Electrochromism is the chemical process behind auto-dimming mirrors. Electrochromatic displays make it possible for these mirrors to become smart glass. Once an electric charge is sent to a smart glass device, the material automatically adjusts the heat and light that is reflected. A vehicle fitted with an auto-dimming mirror makes use of special sensors that detect light. When another vehicle shines light into these sensors, they send a charge to the electrochromatic display that causes it to transform. It is a fairly complicated process to make auto-dimming mirrors function correctly.

Auto-dimming mirrors help a driver avoid the Troxler Effect. This is a condition that occurs when the eye is subjected to bright light. When this happens, the eyes can suffer from temporary blindness. Clearly, this is a problem when driving.

If you've never experienced driving with an auto-dimming mirror, visit Honda of Salem for a test drive. You can see first-hand how this technology works on the streets of Salem.
