This attribute is beneficial for athletes and outdoorsmen who want to receive greater depth perception to enhance their performance. Polarized technology is also used in 3D glasses. One side of the lens is polarized horizontally and the other side is polarized vertically. For 3D movies, two films are actually shown at the same time, shot from slightly different angles. This results in two directions of light that enter the differently positioned lenses, which creates an amazing 3D visual effect.
