I've heard from various anecdotal sources that staring at a monitor too long is bad for your eyes, but I don't recall ever seeing an actual scientific study on it. How long is it safe to work before I should take an eye break, and how long should the break be? Do you know of any way to ease the supposed strain on my sight? Is it even an issue?"
