Astronomer Carl Pulfrich, the namesake for the optical illusion created by 3D Pulfrich glasses featuring a dark lens and a clear lens, was blind in one eye and never got to see the effect named after him.However, the German optical scholar knew the illusion would exist under the right circumstances. The basis for the 3D Pulfrich glasses viewing technique is that images seen through the clear lens reaches the brain slightly faster than images seen through the dark lens. With properly sequenced movement recorded on film or video, objects moving across the horizontal field of vision create the illusion of 3D. Traditional dark and clear Pulfrich works with television broadcasts and video presentations.
