One way mirror glass is one kind of high technology glass mirror which is partially reflective and partially transparent. When one side of the mirror is brightly lit and the other dark, it allows viewing from the darkened side but not the other, so the observer is able to see straight through it, but from the other side, what people can see is a regular mirror.
The effect of one way mirror glass can be controlled by adjusting the brightness of reflecting side(observing side): when the reflecting side is brighter than the other side, observer can see through the glass, but what people from the other side can see is a mirror; when the reflecting side is darker than the other side, it looks like a regular glass from both sides.
