I saw an article that said that someone had come up with data that showed that cell phones had caused about a 35% increase in vision accommodation problems, mostly nearsightedness.

I don't know what the baselines were (before cell phones became so popular) or what age groups they were talking about. I don't recall the article saying much about that.
