Sharks can “blink” and “wink”. Sharks are generally perceived as scary (Thanks, Jaws.) but they can wink quite a charm. The nictating membrane covers and protects a shark’s eyes and – in doing so – gives it a blinking or winking appearance.
100 Mind-Blowing Blink Facts
We can detect taste faster than we can blink. It takes exactly .0015 seconds to detect taste. This is quicker than a tenth of a second a blink takes to complete.
Women blink more often than men. In a study, women blinked an average of 19 times, while for men, it was only 11 times.
Women blink nearly twice as much as men! This is a pure myth! Blink rates are pretty identical for both sexes. Scientists have suggested that the interval between blinks is nearly about 2-10 seconds so an average person blinks about 10 times per minute. Another interesting fact is that we blink less frequently if our eyes are focused on one thing. For instance, while you read, you only blink three times per minute because while reading you are very focused.
The shark is the only fish that can blink with both eyes.
A shark can blink its eyes. It’s the only known fish that can blink both eyes.
Your eyes blink around 20 times a minute. That’s over ten million times a year!
You blink less than half as often when using a computer, which makes your eyes dry out.
An average person can blink seven times every minute when using a computer.
People read faster or slower depending on what they read. Not only do you blink less when you’re on a computer, but reading from a screen also slows you down. On average, people read 10% slower from a screen than from paper! As for the blinking part, did you know that during everyday life, people normally blink at a rate of twenty times per minute? But put them in front of a computer, and that number drops way down to seven times per minute!
