Blink… blink…

Biology tells us that eye blinks occur because our eyes need to be re-moisturized. Is that the only reason we blink? Walter Murch (editor, sound designer, director and screen writer) in his book “In the Blink of an Eye” suggests that we blink for other reasons:

“The blink is either something that helps an internal separation of thought to take place, or it is an involuntary reflex accompanying the mental separation that is taking place anyway.”

Essentially we blink where a film cut would occur! It is like separating ideas with blinks. As character animators, if this is true, this can help us to determine when we should make our character’s eyes blink.
