Frosted privacy film is designed to obscure the view into a building or vehicle, providing privacy for those inside. During the day, frosted privacy film can effectively block the view from outside while still allowing natural light to enter the space. However, at night, when the interior is illuminated and the exterior is dark, the visibility through frosted privacy film can be compromised.

While frosted privacy film may still offer some level of privacy at night, it may not be as effective as during the day. Depending on factors such as the brightness of interior lighting and the distance from which someone is viewing the window, it may still be possible to see silhouettes or vague outlines of objects or people inside.

To enhance nighttime privacy with frosted privacy film, you can consider additional measures such as using curtains or blinds to further block the view from outside when interior lights are on. Additionally, choosing a higher opacity or thicker frosted film may provide better privacy both during the day and at night.
