“Scientists have created video games that add an important element of fun to the repetitive training needed to improve vision in people - including adults - with a lazy eye and poor depth perception,” notes Medical News Today. “The training tools, including a Pac-Man-style "cat and mouse" game and a "search for oddball" game, have produced results in pilot testing: Weak-eye vision improved to 20/20 and 20/50 in two adult research participants with lazy eyes whose vision was 20/25 and 20/63, respectively, before the training began. Unlike the common use of eye patches on dominant eyes to make lazy eyes stronger, this type of testing uses a "push-pull" method by making both eyes work during the training. Patching is push-only training because the dominant eye remains completely unused. With push-pull, both eyes are stimulated but with the weaker eye exposed to more complex images that create a stronger stimulus.” Read more.
