3D TVs is pretty much stereo for your eyes. One right image and one right image. In fact 3D video and pictures is sometimes done by using left and right lenses that are slightly off set. How offset? Its as about as offset as a pair of human eyes. Its about 4 inches or 7 centimeters. Its called stereopsis.
