People who have difficulty seeing traffic lights or cars at night, facial gestures, or when a flame is burning on a stove often suffer from poor contrast sensitivity, a condition thought to be correctable, if at all, only by eyeglasses, contact lenses or surgery. Researchers now say they may have found a way to improve contrast sensitivity naturally with the help of an unlikely source—video games.
In a study published today online in the journal Nature Neuroscience a team of researchers led by University of Rochester in New York State professor of brain and cognitive sciences Daphne Bavelier describe a specific video game training regimen that could improve contrast sensitivity, helping those afflicted with the problem notice even very small changes in shades of grey against a uniform background. Poor contrast sensitivity affects thousands of people worldwide, including the elderly and those suffering from amblyopia, also known as "lazy eye," Bavelier says.
