How One Way Window Film Works During The Day And At Night
One way window film depends on light difference.
The brighter side becomes harder to see through, while the darker side can usually see out more clearly.
During the day, when the sun is brighter outside, people outside will find it harder to see in.
At night, when your indoor lights are brighter than outside, the effect can reduce or reverse. If you need day-and-night privacy, frosted film, blackout film, curtains, blinds or smart film may be more suitable.
