Prevent nosy, unwanted onlookers from peeping through your window during the day with window film tint. It gives the window a mirror-like, highly reflective look on either the outside or the inside of the window depending on the lighting conditions. The privacy coverage of this one way window film depends on the light intensity. In general, during the daytime, people inside can see through this glass window tint, while people outside can’t see in due to the strong sunlight outside. However, when the indoor light is stronger than the outdoor during the nighttime, people outside can see in.
