A recent study in Nature, the weekly scientific journal, suggests that playing video games can be good for one’s vision. Researchers at the University of Rochester say that action game players react to fast-moving objects more efficiently and can track 30% more objects than non-gamers. Video and computer games, it seems, can actually help players train their visual attention. According to one German neurobiologist, the nerve cells may shift shape from playing these games and this helps the nerve cells communicate more effectively with each other. However, only the shoot-em up games helped improve vision. The more sedate games like Chess, Scrabble, and Tetris, even when played electronically made no visual improvements.
