Are video games better for you than carrots?

This may be a stretch, but studies are currently being conducted to find out if high-action video games are actually good for your ocular health. Meaning, of course, that when your parents said both, "Playing all those video games will ruin your vision!" and "Carrots are the best thing for improving your vision!," they were—GASP!—wrong! Well ... maybe.

Apparently, the ability to discern between different shades of gray is an attribute in humans that is unable to be improved; however, it has recently come to the attention of scientists at the University of Rochester that playing video games that utilize high levels of action (like first-person shooters) actually improves the aforementioned attribute—meaning said video games actually improve your vision.
