I spent 10 hours a day on computers when I wasn't at school during middle school. Started at the end of primary school and continued until now. I pass the letter-reading tests at the GP when I'm not too tired, so I think I have pretty good vision. Maybe that's because I didn't always have a computer nearby and had to spend time outside too as a kid.
