From one viewing angle VisionControlFilm is optically clear.

As the viewing angle changes, so does the opacity of the glass
until it appears fully frosted.

Each of the four types of VisionControlFilm offers two choices of viewing angle according to whether the film is applied vertically or horizontally.

For W-0055 and Y-2555 the effect can also be flipped according to the application direction. For example when W-0055 is applied horizontally the effect is frosted from 0/+55° or 0/-55°.
