It is a material with bunches of tiny lenses embedded into it. This makes it blur incoming light from behind it while still allowing most of it to pass through in some direction.

Imagine a flat sheet of the material with a person standing a few feet behind it. Our person is wearing a blue jacket and the environment around them is yellow.

From what directions can light fall on the material? Basically from 180 degrees, half a sphere in direction right? But the person only takes up a relatively small number of those angles. What the material does is mix all that light together so what you see is mostly yellow with a small amount of blue instead of the clearly blue jacket.
