Do you know someone with the lazy eye? If you did not know, lazy eye is defined to be visual disorder where the brain ignores one of the “lazy eye’s” inputs.
People with “lazy eye” cannot see in 3D and they cannot judge distance very well compared to others because they need to use both eyes in order gauge the distance. Prior to a Canadian-led study, the only treatment available was covering the stronger eye with an eye patch in order to force the brain to use the weaker eye and fix itself. The only problem with this was that it could have only been done with in children. As adults, it is believed to be an untreatable disorder because adult brains are too settled in and cannot learn to effectively use the lazy eye.
However, in this new treatment developed at McGill University in Montreal, they found that playing video games with both eyes (using specialized goggles) can dramatically improve vision in adults with lazy eye.

How did the treatment work? Participants play the video game Tetris using a pair of head-mounted video goggles. One side of the goggles sees the falling pieces of the game, while the other side sees the pieces sitting at the bottom of the screen. The participants play this game while using both eyes simultaneously. They repeat this process for an hour a day for two weeks. In that time span, nine adults with lazy eye showed dramatic improvements in the vision of the weaker eye and in their 3D perception as well.
By having both eyes work together, they can get the brain to efficiently correct itself and use both of the eyes’ inputs. Tetris is not the only game that can be used to effectively fix the lazy eye disorder. Any interactive, visually intensive game that forces both eyes to be used will ultimately be the solution to the lazy eye disorders. The researchers of this study hope to use this study to perfect a treatment for lay eye disorder and replace patching in children with something more fun and enjoyable.
