So, I can't think of a better place to ask this than people who spend hours playing games on their phones. So, for those of you who use your iPhones a lot, have you had any eye trouble from it? Like double vision?

My eyes are screwy, and I thought it was all the iPhone, but my eye doc thinks it might be something that was there already and the iPhone just exacerbated it. So I want to see if this is something others experience.

Thanks!
