And hindi ka ba kita talaga sa loob, maski idikit yung mukha ng tao?
wala naman ganitong klaseng tint. the closest would be a 1-way mirror/glass tulad sa interrogation room ng police or FBI.

A true one way mirror does not, and cannot, exist. Light always passes exactly equally in both directions. However, when one side is brightly lit and the other kept dark, the darker side becomes difficult to see from the brightly lit side because it is masked by the much brighter reflection of the lit side.
