Charles Wheatstone invented 3D glasses in 1838 while working in his office as a scientist. He called his wife to tell her that he had invented 3D glasses, a device that allows the viewer to see 3D images when watching special videos or viewing web pages through different technologies like anaglyph or polarized lenses. The document then provides some examples of YouTube videos that demonstrate 3D effects through different types of 3D glasses technologies.
