Is window film see through?

In by Raleigh Window Tinting

The level of optical clarity will depend on the window film that you select. Some 3M window films are designed to preserve the appearance of your windows, so these films are optically clear. Other window films are tinted, offering excellent heat rejection, glare reduction, and a stylish look. Most 3M films are available in a variety of tint levels, allowing you to choose the desired level of tint based on your preference, goals, and where the film is being applied.
