great article short but good by Toms hardware about UT helping peoples vision from playing 1hr a day for 1 month by 20% over people who played tetris.
anyone going to Univerisiy of Rochester that wants to get me into that testing program!?! =D
Now I have an excuse to play video games!!! 
But I doubt my parents will go for it.
Shmups are a great way to improve vision. Take DoDonPachi, for example, the bullets are colored pink and blue so they stand out against the background and are easy to spot.
dude, they say first person video games help with shooting accuracy in real life. im an amazing shot, and i dont think it works.
