Blinking

Blinking keeps eyes safe from potentially damaging stimuli, such as bright lights and foreign bodies like dust.

A shark is the only fish that can blink with both eyes.

Women blink nearly twice as much as men.

A blink lasts approximately three seconds.

The normal rate of blinking is 15-20 times a minute. However people blink less while lying, and up to eight times faster than usual afterwards.

You blink about 84,000,000 times a year.

If all the time our eyes are shut when blinking is added together, we would spend 1.2 years of our walking lives in pitch darkness.

Our eyes are closed for roughly 10% of our waking hours overall because we blink so much.

The average computer user only blinks seven times a minute when in front of their screen.

In “Silence of the Lambs”, Hannibal Lector (Anthony Hopkins) never blinks.
