American Paper Optics produces 3d polarized glasses featuring the best quality 6-ml polarizer film that is offered. We are THE #1 source for all types of 3d polarized glasses and applications. American Paper Optics manufactures both circular 3d polarized glasses and linear 3d polarized glasses (45°/135° and 0°/90°). Our 3d Polarized glasses contain specialized filters for viewing slide shows, multi-media displays, concerts, movies, and ride simulators. 3D Polarized glasses create the illusion of three-dimensional images by restricting the light that reaches each eye. To present a stereoscopic motion picture, two images are projected superimposed onto the same screen through orthogonal polarizing filters.
