Finally, kids have another excuse to stay inside and play video games when it's a nice day outside besides "hand-eye coordination." Apparently video games, specifically "action games" like Unreal Tournament, improve vision by up to 20%. Eat that, carrots.
Researchers at the University of Rochester tested both Unreal Tournament and Tetris, with Tetris doing basically nothing to your eyesight and UT giving that 20% boost. Well, you'd better log on and play some Facing Worlds CTF… it's for your own good.
