Blink Reflex examples. The images are explicitly for educational purposes and to help players and coaches. A blink is approx. .495 sec. In baseball, a fastball at about 90 mph reaches the batter in about .485 sec. You blink you don't see the ball. See other sports examples. My camera shoots 2 sequential frames in .4 sec and three in .6 sec. What was seen or missed? Updated on a regular basis, please return.
