Ponca City, We love you writes "According to a new study, people who played fighting games on their PCs became up to a 58 percent better at perceiving fine contrast differences, an important aspect of eyesight. The breakthrough is significant because it was previously thought that the ability to notice even very small changes in shades of grey against a uniform background could not be improved. Contrast sensitivity is the primary limiting factor in how well one sees. Volunteers in the study played intensively for 50 hours over nine weeks with either Unreal Tournament 2004 and Call of Duty 2, and the results were compared with another group who played The Sims 2, which is richly visual but does not require as much hand-eye coordination. The improvements lasted for months after game play stopped. The new finding suggests action video games could be used as training devices as a useful complement to eye-correction techniques, since gaming may teach the brain's visual cortex to make better use of the information it receives."
