Using 3D viewing systems to restore binocular vision
Diplopia is one such virtual reality game from San Francisco. The game, which is still in beta testing, is designed to help people with lazy eye amblyopia and crossed eye strabismus. It recently closed a $700,000 seed round, led by SOS Ventures.
While many will tell you that playing video games are bad for your eyes, the founder, James Blaha, fixed his own lazy eye with the game he invented with Manish Gupta.
Basically, the system restores binocular vision so that patients may again see in 3D. Contrast the above story with the (often badly sourced) claims that 3D TV or 3D movies harm vision.
