How do Auto-Dimming Rearview Mirrors Work?

Bright lights reflecting from a rearview mirror at night can be a nuisance or even cause a driver to develop a temporary blind spot when trying to view the road ahead. In order to avoid this potentially dangerous situation, car designers have developed an auto-dimming mirror.

Rearview mirrors in many new cars possess a light-detecting sensor that gauges how bright the light shining into it is. Once it exceeds a certain threshold, the sensor fires a small electric charge, which activates a light-absorbing gel housed just behind the glass. This gel disperses over the interior surface of the mirror and absorbs the light. Drivers can still see the traffic behind them on the mirror's surface, but the images are dimmed slightly.
