Q. Can you see through one-way decorative window film?

Answer

One-way window film only transmits what is two times as bright on one side of the film as what is transmitted on the other. That's why most police buildings have just one-way glass in their windows. It allows the cops to peer inside a room without drawing attention to them. Anyone talking or doing anything in plain sight won't notice their presence. One-way window film might be thought of as a "see out but not see in" film. To make a one-way window privacy film a thin layer of reflective metal is layered in between an adhesive bottom and a protective top.
