Diplopia – A VR Game to Help Strabismus and Amblyopia is exactly what it sounds like. This sounds like a great gaming project! The game is meant to help people who have some eye issues strengthen their weak eye to restore (near) perfect control over their stereo-vision.
You can contribute to the project at IndieGogo (only 6 days left!).
From the developer:
Strabismus, better known as crossed eye, is present in about 4% of children. In those affected both eyes do not line up properly causing diplopia (double vision), amblyopia (lazy eye), and loss of vision in one or both eyes. Since the brain receives conflicting information from the two eyes it often learns to disregard the weaker of the two, suppressing it. This leads to a loss of depth perception and 3D vision.
