You know that little nub sticking out the bottom of the mirror? Flick that and your mirror will flip to another angle so the lights are no longer pointing at your face.

Rear view mirrors actually contain 2 mirrors, so when you flick it you get the same image at the same angle, but only with 10% or so of the light actually being reflected towards your eyes.

Doesn't work when the high beams are on and tailgating you for going "only" 10 MPH over the speed limit. Also many newer cars are coming out with "auto dimming" mirrors without the switch but that don't quite seem to cut out as much light. The problem isn't just with lights either, it's with a lot of different features including mirrors that can't adequately capture blind spots and bumpers that cause more harm due to mismatched heights. The differences in vehicles sizes overall probably lead to quite a few avoidable traffic fatalities and accidents.

Is that why I'm getting all these downvotes on the comment above? Dudes and dudettes, that doesn't work on the side mirrors, which also have that effect.
