[size=+0]Video game players may get an unexpected benefit from blowing away bad guys—better vision. Playing “action” video games improves a visual ability *****crucial for tasks like reading and driving at night, a new study says.

[size=+0]The ability, called contrast sensitivity function, allows people to discern even subtle changes *****in shades of gray against a uniformly colored backdrop. It’s also one of the first visual aptitudes to fade with age.

[size=+0]That’s *****why a regular regimen of action video game training can provide long-lasting visual power, according to work led by Daphne Bavelier of the University of Rochester.

[size=+0]Previous research shows that gaming improves other visual skills, such as the ability to track several objects at the same time and *****paying attention to a series of fast-moving events, Bavelier said.
