A girl with amblyopia watching one of the dichoptic movies on a passive 3D display while the child wore 3D cinema glasses. Movie scenes were separated into irregular blob-shaped areas that were complementary for the amblyopic and fellow eyes so that the entire scene could only be perceived if binocular vision was used to merge the parts of the picture shown to each eye. Images were presented at high contrast to the amblyopic eye and low-contrast image to the fellow eye. The contrast-imbalance overcomes suppression of the amblyopic eye and reveals binocular vision.
