Also called stereoscopic glasses, 3D (three dimensional) glasses are capable of recording three-dimensional visual information or creating the illusion of depth in an image. First invented by Charles Wheatstone in 1838, 3D glasses create the illusion of depth in photographs and movies by presenting a slightly different image to each eye. In other way, 3D glasses provide the eyes of the viewer with two different images that represent two perspectives of the same object so that the brain will receive a depth perception. This is the basic principle of 3D glasses.
Among the various 3D glasses styles, polarized 3D glasses are special. They create the illusion of three-dimensional images by restricting the light received by the eyes. Using orthogonal polarizing filters, polarized 3D glasses project two images onto the same screen in order to show a stereoscopic vision. Through these filters, light that is similarly polarized can pass so that each eye receives only its separately polarized image, and then a three-dimension effect appears.
Currently, you can easily find 3D glasses online. There are some professional 3D glasses online stores, such as 3dglassesonline.com, 3dglasses.net, 3dglasses.com and berezin.com. Depending on your special event or purpose, a wide variety of 3D glasses applications and styles are available, such as Anaglyph 3D glasses, Pulfrich 3D glasses, hand held 3D glasses, Proview professional 3D glasses etc… You can also get 3D glasses in clip-on.
