Any kid would like this cure. The Daily Mail is reporting a daily dose of videogames saved the eyesight of a 6-year-old boy.

Since the age of 4, Ben Michaels suffered from a condition called amblyopia, or severe lazy eye syndrome, which caused the vision in his right eye to gradually decrease. Had it gone untreated, Ben could have lost his sight permanently.

He was referred to Ken Nischal, a consultant at Great Ormond Street Children’s Hospital in London, who told Ben to play videogames every day with a patch over his good eye. After just one week of playing Mario Kart on a Nintendo DS with his twin brother for two hours daily, his vision had improved 250 percent.

“When he started he could not identify our faces with his weak eye,” Ben’s mother, Maxine Michaels, said. ”Now he can read with it, although he is still a way off where he out to be. He was very cooperative with the patch, it had phenomenal effect and we’re very pleased.”

Nischal said the repetitive eye movement involved in playing videogames trains the eye to focus and could help thousands of people, young and old.
