I’ve been warning a few friends and family about what I see as a looming problem, and that is the potential negative impact to eyesight posed by smartphones. Here’s another article from CBS Pittsburgh about the increased incidence of nearsightedness among young people, tied perhaps to the rise of personal electronic devices. (Via Drudge).
So, beware! Take breaks when reading on a smart phone or tablet, or doing anything on them for that matter, and adjust the brightness down when appropriate. Try to limit the time you spend on electronic devices before you go to bed. (I say that, naturally, as I type this on my laptop at nearly 1am!).
