I haven't heard of this before. Could you provide a reference to back the up?

@StevenJeuris It's a pretty common issue, especially among (but not limited to) those who wear contacts. A reference would be nice, though.

Well, I have it myself. I though it was not so common but then I heard someone mention it in a presentation on youtube. Anyways, the edits from @anongoodnurse should be sufficient to back it up :)

Long time screen users like software developers sometimes use computers so intensely that they do not blink enough with their eyes. This leads to dry eyes.

Is it possible to induce blinking by manipulating the screen, for example by regularly making it completely black for a split second?
