A British youth overcame what is called "lazy eye syndrome" thanks to a doctor's prescription of Mario Kart DS, restoring his right eye from "near blindness" to a 250 percent improvement.         

At age 5, Ben Michaels was diagnosed with ambylopia in his right eye, which results in a steady decline in vision in that eyeball. Untreated he would have gone completely blind in it. His doctor, however, told Ben to play Mario Kart DS with an eye patch, which trained the "lazy" one to work harder and thus to improve.

I can relate to this kid. A little interesting tidbit of myself, but I had something similar on my left eye which I spent most of my years as a kid wearing a eye patch on my right. I had to do this to strengthen my left eye from going blind.

It worked but I had to wear the patch everywhere I went, to school, outside in public, and home...everywhere. Yeah, you can imagine the teasing I got. But to be honest, they weren't that cruel to me.

This kid played Mario Kart 2 hours a day but I had to wear this patch for years. But unlike this kid, my left eye didn't improve that much. To this day, I'm still almost blind but what the patch did was prevent me from being cross-eyed.

If only I had a DS back in the day. Maybe my eye would've been better. Anyway, just thought this article was interesting.
