Of Interest: How Quick is a Wink?
Dick Moss, Editor, PE Update.com

We all know the saying, “Quick as a wink.” But how quick is that?

According to Adler's Physiology of the Eye, edited by Robert Moses, a wink takes .3 to .4 seconds.

As quick as a wink might seem, this fraction of a second can be significant in many sports. For example, in a 100m race run at Donovan Bailey's world record time of 9.84 seconds, a wink represents 3 to 4 meters—a significant difference in sprint events.
