Yeah, I'm a bit suspect on this research myself. Where I'd see it less as playing lots of video games and more how close you are to the screen and if you're are doing such at night or in a dark room. Since that puts you're eyes under more straight then simply the video games themselves. Plus, just simply the fact that a lot of people in general are having eye troubles, even when they don't play video games or watch a lot of television.
