About nine person out of ten I know aren't aware of the fact that the rear view mirror in most cars can be manually set to "night mode". The rear view mirror has two positions: one for day-time and one for night-time (which dims the brightness of other cars' headlights).
There's a manual switch which accepts two position and which is located on the back of your rear view mirror.
It's something you need to switch manually twice a day: once in the morning to put it back in "day mode" and once at night, when it becomes dark. You don't need to reconfigure anything: the position of the rear-view mirror stays correct and you continue "viewing the same thing", just dimmed enough as to not be blinded by bright headlights in your rear-view mirror.
Honestly, as I wrote earlier, most people I know who drive cars are totally unaware of that switch even though they're driving since 20 years.
