New research suggests playing action video games that involve firing guns such as "Gears of War," Lost Planet," and "Halo" can improve your eyesight.
I wouldn't be surprised if the same phenomenon occurs from shooting real guns. Tell me as a kid you wouldn't have rather heard "Let's go to the range" than "Eat your carrots--they're good for your eyes."
Plus it'll have the side benefit of sticking it to anti-gun pediatricians.
