Scientists Demonstrate First-Person Shooter Games Improve Vision

Need an excuse to log a few more hours playing Call of Duty or Medal of Honor? Scientists demonstrated improved vision in test subjects after daily doses of first-person shooter games.

Scientists at McMaster University took subjects who, as the result of surgery correcting congenital cataracts, had less than 20/20 vision. Subjects played Medal of Honor for a total of 40 hours over the course of 4 weeks before having their vision retested. The results? The CBC reports:

The participants found improvements in detail, perception of motion and in low contrast settings.

In essence, players could now read about one to one-and-a-half more lines on an optometrist’s eye chart.

“We were thrilled,” Lewis said. “It’s very exciting to open up a new world of hope for these people.”

Researchers don’t know exactly how playing the game was able to help restore some vision for the patients.

They hypothesize the adrenaline created playing the came creates dopamine — which when combined with the level of attention to detail players need in a Medal of Honor match — can actually rewire visual connections in the brain.

    super that it might “hypothetically” aid in rewiring visual connections in the brain, but I doubt that FPS’s will ever be seriously advocated by any College of Physicians as standard form of therapy for the visually impaired,…for obvious reasons.
