Play video games can improve eye vision

According to a recent study out of the University of Rochester, playing video game improves your bottom line on a standard eye chart. People who play action-packed video games can boost their visual acuity by about 20% a month.

The researchers took on the nigh-impossible task of digging up a subject pool of Rochester students who never played video games. They gave the students a visual test where they identified the orientation of letters in a clutter. Students then spent a month playing either the action game Unreal Tournament or the less visually exhilarating (but still wonderful) Tetris for one hour a day. After a month, the Tetris players were still their average old selves, but the Unreal Tournament players gained unreal vision. Research concluded that "games push the human visual system to the limits and the brain adapts to it. That learning carries over into other activities and possibly everyday life."
