Slaying hordes of bad guys, the more the better if fast paced video games improves vision, a study published on Sunday showed for the first time. Far from being harmful to eyesight, as some had feared, action games such as Counter-Strike, Call of Duty, or Left 4 Dead provide excellent training for what eye doctors call contrast sensitivity.
Contrast sensitivity is the ability to notice tiny changes in shades of grey against a uniform background, and is critical to everyday activities such as night driving and reading. If often degrades with age. The findings, published in Nature Neuroscience, revel a previously unsuspected adaptability in the brain, and could open the way to new therapies.
This is not a skill that people were supposed to get better at by training," said Daphne Bavelier, a professor at the University of Rochester in New York state and the study s lead researcher. It was something that they've corrected for at the level of the optics of the eye, to get better contrast detection you get glasses or laser surgery. What they've found is that even without this correction you can help your brain make better use of whatever information is received from your retina.
