That's not good news, because anti-videogame nuts will take the part about videogames changing the way your brain works and run with it.

Also it says it affects the way your brain interprets visual signals, not your eyesight itself.

 

I'd think video games would be a decent way of improving eyesight, but only in that particular game, and for that particular play session. I suppose it'd help to test this further; take a UT2K4 pro, where reaction speed, aim accuracy, and on-the-fly terrain tactics make all the difference, and make him/her play some platform or puzzle game. Once the initial learning curve is busted, would the player be equally skillfull? Furthermore, would being able to headshot-click someone in 0.438 seconds or rapidly launch Meteos help someone in the workplace? I guess that also depends on your job; like, whether you're a cube farming programmer, a gardener, or a short order cook. Each of those professions get good at "seeing" things necessary for their job. A gardener would probably be able to spot the bright colors of a harmful insect from across the greenhouse, and a computer programmer could probably scroll through code and notice typo'd or out of place keystrokes quickly. This is all assuming months, or years, of experience though, so I dunno.

I do know that every year I seem to sit closer and closer to the monitor. I'll probably be blind as a bat, and wearing thick glasses, by age 40.
