Description:Turn your TV into 3D!
The 3D effect based on the phenomenon discovered by Carl Pulfrich. One dark gray and one clear
lens. The image through the dark lens reaches the brain slightly later than the image through the
clear lens, creating the illusion of 3D. Works with objects or scenes moving horizontally across
the field of view. This is one of the only viable ways to experience broadcast TV in 3D. Used for
3D viewing of TV, video, and computer screens.
