For instance, some customers may be wondering how auto-dimming rearview mirrors work.

There may be a bit of geekdom behind how auto-dimming mirrors work. The process itself is called electrochromism which is technically a darkening of the mirror when sensors are trigger by ambient light. The sensors within auto-dimming mirrors are either camera or photodiode-based photodetectors.

The sensors within the mirror work in conjunction with a microprocessor to notice glare from a trailing vehicle. This, in turn, sends a charge through the electrochromic gel that causes material inside the gel to react resulting in a lessening of oxidation and a darkening of the mirror. In this state, the mirror reduces the amount of light that reflects into the face of the driver.
