Seriously? People still use those glasses?
Long before VR headsets, one way to view 3D was using special glasses with red and cyan glasses to filter red and cyan overlayed images so the viewer would perceive a 3D image. A red filter over the left eye and cyan over the right. In our pictures we have chosen near objects to be close to zero-parallax (close to the screen level without jumping out at you) in order to reduce possible eye-strain i.e prevent objects from appearing in front of your screen.
