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.
Unfortunately, people typically don't blink their eyes normally when using a computer or other digital devices or simply watching television intently. Specifically, computer use affects both blink rate (how frequently we blink) and blink completeness (whether the eyelids close completely during a blink).
Is it possible to induce blinking by manipulating the screen, for example by regularly making it completely black for a split second?
