There is a lot of technological features inside of many new automobiles. One of the most popular features that drivers enjoy is auto-dimming rearview mirrors. But how do auto-dimming rearview mirrors work?
When you're driving, there's almost nothing quite as distracting as a bright pair of headlights behind your vehicle that shines into your rearview mirror. Unfortunately, the problem doesn't end there. As this driver turns off or exits your lane, it can create a distracting and potentially dangerous blind spot in your field of vision.
Auto-dimming rearview mirrors contain a few sensors, typically two of them. These sensors work together with a powerful microprocessor to automatically detect glare from a bright light behind your vehicle. After this happens, a charge makes its way through a layer of electrochromic gel inside of your mirror. Next, oxidation-reduction reactions take place that restricts how much light you see. This process allows drivers to have an easier time driving with bright lights behind them.
