Glasses-free 3D technology works by using a physical layer that separates what your left and right eye sees. It does this using a long, thin lens that runs over the surface of the TV. This process is identical to those 3D cards you move to generate an image that either moves, or changes.

Producing television or video games that works on 3DTVs would be a difficult undertaking at this stage of the game, because if the image you are looking at isn’t properly aligned with the lenses, it simply won’t work. Which is why there are several companies investing a lot of money into developing this technology.
