Video Game Treatment For Lazy Eye Restores 3D Vision

CBC News reports that a Canadian-led study has found that playing video games with both eyes can dramatically improve vision in adults with lazy eye — a condition thought to be all but untreatable in adults.

Lazy eye, known to doctors as amblyopia, is a problem in which a person sees better in one eye than the other and the brain effectively turns off the weaker eye. It affects up to three per cent of the population. People with lazy eye can’t see in 3D and can’t judge distances as effectively as people with normal vision because those tasks require the use of both eyes at the same time.

“It’s relatively quick, surprisingly quick,” said Robert Hess, director of the opthalmalogy research department at McGill University and the Research Institute of the McGill University Health Centre in Montreal. “More importantly, in a majority of cases, they get back their stereoscopic or their 3D vision.”

That may mean being able to watch 3D movies for the first time.
