The title says it all.
I always wondered how does pushing that little button on the bottom of the mirror dim the reflected lights at night and yet keeps the same viewing angle.

Think about it this way. The manually dimming rear view mirror isn’t actually dimming anything sorta. It’s just a mirror with a sort of differently angled window/mirror in front of it. When you move the tab, you move the whole both of them but place the one that offers the dimmer reflection in place of the one that gives the bright reflection.
edit: i should add that the brighter one is still reflecting all bright lights… it’s just pointing them somewhere else since the tab turned the whole structure the same amount of degrees that the two reflective surfaces are angled at.
