There has been lots of talk and research in the last decade or two about the effects of stereoscopic 3D video on young eyes.  Some research shows irreparable damage in the ability to discern stereo, and some research shows no damage whatsoever.  It’s anyone’s guess what the real answer, but now there’s a new player in the game: Stereoscopic 3D can actually cure vision problems.

The new treatment involves setting up the video game of Tetris so it can only be played effectively using both eyes. The game involves rotating puzzle pieces as they fall so that they interlock with other puzzle pieces sitting at the bottom of the screen. The researchers split the image between the eyepieces of a pair of head-mounted video goggles so that one eye could only see the falling pieces and the other eye could only see the pieces sitting at the bottom of the screen.
