Many will tell you that video games are bad for your eyes, but James Blaha doesn’t buy that theory. He’s developing a crowdfunded virtual reality title, Diplopia, that could help restore 3D vision. The Breakout variant trains those with crossed eye problems to coordinate their eyes by manipulating contrast; players score well when their brain merges two images into a complete scene. Regular gameplay could noticeably improve eyesight for adults that previously had little hope of recovering their depth perception, Blaha says. The potential solution is relatively cheap, too — gamers use an Oculus Rift as their display, and they can add a Leap Motion controller for a hands-free experience. If you’re eager to help out, you can pledge $20 to get Diplopia, and $400 will bundle the app with an Oculus Rift headset. Check out a video demo of the therapeutic game after the break.
