Scientists at McGill University in Montreal, Canada, have confirmed what kids have been insisting for ages: playing video games can be good for you. Specifically, playing block-building games like Tetris can do more to fix lazy eye than traditional treatments.
Lazy eye (medical name: amblyopia) is a condition in which vision doesn't develop properly in one eye. It can cause permanent sight problems if left untreated, since the brain eventually just stops processing the blurry images coming from the underfunctioning eye. According to The Eye Digest, about 3 percent of people in the United States have amblyopia.
