That's the takeaway from a study by a group at the Helen Willis Neuroscience Institute at the University of California, Berkeley. According to GamePolitics' summary of the study, 40 hours of gameplay using the "bad" eye was equivalent to 120 hours of normal, non-game-specific occlusion therapy. The test patients experienced an average of 30 percent improvement in visual acuity.
Joystiq is not qualified to dispense medical advice, but it sounds like -- if your bad eye is still good enough to figure out what's going on in a video game -- this might be worth trying. Suddenly the impossible dream of being able to kind of see the 3DS's stereoscopic effect seems within reach for the first time.
