Blink if you're reading this story on-line! Blink because when staring at a computer — for hours on end, as if seeking truth on the surface of the moon — we blink less often than is healthy.

Infrequent blinking is one cause of dry eye syndrome, suffered by more than 10 million Americans, according to Dr. J. James Rowsey, a corneal and refractive surgeon at St. Luke's Cataract and Laser Institute in Tarpon Springs, Fla.

The symptoms include irritation, itching, burning, blurred vision — even excessive tearing. (Via Daily Press)
