Video Gaming Improves Vision

Yeah, I'm just as shocked as you.

According to a University of Rochester study, playing action-oriented video games increases fine-contrast vision.

Normally the eye cannot discern between slight differences in shading easily and scientists had believed that increasing one's ability to see such minute differences would not be possible.

The study shows that the gamers had become 58% better at distinguishing between the shading as the result of their video game play by showing "action video games decrease visual crowding and increases visual attention," which, when translated, means that your eye is able to pick out individual elements of things that are packed tightly together or have a lot of detail to them and that your eye is able to attend to more objects in its visual field.

tl;dr - You see more and see more details.

The study was reported in March's Nature journal.
