blinky-hug

The "blinky-hug effect" is a curious phenomenon that occurs late at night, wherein the afflicted will feel the distinct impression that his or her eyes are receiving tiny, warm hugs each time he or she blinks. The effect is extended into a kind of loving embrace when the eyes are closed for longer periods, and can be difficult to recover from.
It should also be noted that those wearing contact lenses will feel the blinky-hug effect sooner and more dramatically than their un-lensed peers.
