The auto-dimming rearview mirror is a favorite feature among our Lewis Motor Sales Inc team serving Lafayette, IN. It reduces blinding glare from high beams when you're driving at night. It can also reduce glare during daytime driving. Here's how.
What Are Auto-Dimming Mirrors Made Of?
An auto-dimming mirror is an electrochromic mirror. An electrochromic mirror darkens when exposed to bright or ambient light. Auto-dimming mirrors contain electrochromic gel, a gel that changes in opacity in response to light. They also contain glass panes (the reflective surface) with an electrically conductive coating, light sensors, and a controller.
How Does an Auto-Dimming Rearview Mirror Work?
When an auto-dimming rearview mirror's sensors detect ambient light or glare, an electrical current passes through the mirror's electrically conductive coating. Exposed to an electrical stimulus, the electrochromic gel sandwiched between the mirror's glass panes darkens, reducing glare. When the source of the bright light subsides, the mirror returns to normal.
