Most drivers can relate to the frustration of high-beam headlights shining into their rearview mirror and causing problems while driving at night. Among the best innovations in recent years are auto-dimming rear-view mirrors. As the name implies, they are mirrors that protect your vision by automatically absorbing light, leading to safer and more comfortable driving conditions.
The mirrors work by sandwiching a revolutionary substance between two panes of glass in your rear-view mirror housing. This substance, known as electrochromic gel, reacts to electricity by changing color. Your rear view mirror senses light shining on it and immediately sends an electric charge into the gel, causing it to darken and absorb the excess light, preventing it from shining in your eyes. When the light disappears, the charge ends, the gel returns to its original color, and your mirror reflects the scene behind you.
