PATIENTS with a rare eye condition underwent a new therapy which included playing shoot-em-up video games for 40 hours per month.
Their vision improved so much that they were able to read as many as two lines further down a standard eye tests chart.
Games that require players to respond to action directly ahead of them and in the periphery of their vision strengthened the visual system in adults whose eyesight had been severely impaired from birth.
The surprise results challenge the view that computer games are bad for the eyes and suggest that the adult brain can be trained to overcome certain conditions.
Daphne Maurer, a psychologist at McMaster University in Hamilton, Ontario, who announced the study results said: “All of them showed substantial improvements in eyesight. They also came to see objects with lower contrast, and more subtle differences among faces and moving objects.”
