You can exercise your eye now at Tetris through a simplified version (Beta) available on computer (accessible from this page) or smartphone / tablet.

You must use anaglyph glasses (3D glasses the cheapest in the market, available for example here) in order to play.


  • This game reproduces the dichoptic vision system, used in the latest studies for the treatment of amblyopia
  • You should not play if you have a strabismus (this may cause double vision)
  • Take a 5 minutes break every 15 minutes.
  • If you experience headache or double vision, stop playing immediately and contact us.
  • in the clinical studies, patients play an hour a day for five weeks (see the clinical studies page)
  • this game is not a medical device

To play :

  • move the blocks with the arrows right, left and down on your keyboard
  • rotate the blocks with the up arrow on your keyboard

Goal of the game :

The player must complete as many lines as possible. Once a line is completed, it disappears and the blocks located above drop one position. This conserves space for future blocks.
