Contra Vision® White 24/7 Concealed Vision™ is a one way window film that works at night. Most one-way vision films can only provide privacy during the daytime. At night the films become see-through if the inside is illuminated and blinds or curtains are needed. If night privacy is needed then Contra Vision offers one product which obscures the vision into buildings even if they are illuminated.
Contra Vision® White 24/7 Concealed Vision™ is a translucent white perforated window film which works at night and provides some privacy 24/7, but careful consideration must be given to the back lighting to get the best results.
Contra Vision White 24/7 Concealed Vision achieves a degree of night privacy when light passes through the material and causes it to glow slightly, creating a distraction to the see-through. Ambient lighting from inside the building is enough to provide some illumination. This effect can be enhanced by removing point sources of light from directly behind the window and adding spot or flood lights from outside the field of vision. Even if the internal lighting is sub-optimal, night-time privacy will still be better than with conventional perforated window film.
