What is the measurement of a blink of an eye?
The CLS measured a mean blink frequency of 29.8 ± 15.4 blinks/min, a blink duration of 0.26 ± 0.21 seconds and an interblink interval of 1.91 ± 2.03 seconds.
How fast is a blink of an eye in seconds?
Each blink lasts between 0.1 and 0.4 seconds. Given how many times the average person blinks per minute, this makes up about 10 percent of the time you’re awake.
How many blinks per minute is normal?
It has been reported that the normal spontaneous blink rate is between 12 and 15/min. Other studies showed that the interval between blinks ranges from 2.8 to 4 and from 2 to 10 s. A mean blink rate of up to 22 blinks/min has been reported under relaxed conditions.
What is faster than the blink of an eye?
Our Fingers Accelerate 20 Times Faster Than A Blink Of An Eye While Being Snapped. At a rotational acceleration of 1.6 million degrees per second, it’s the fastest movement humans produce.
What does blink rate mean?
Blink rate (BR: the number of blinks per minute) during choice-response tasks can provide a reliable measure of cognitive processing (e.g., Wascher et al., 2015 in the central nervous system Ichikawa and Ohira, 2004).
How many milliseconds is a blink?
On average the human blink lasts only a tenth of a second which is 100 milliseconds. Wow, that’s fast! Sometimes, it can even last up to 400 milliseconds. To put it into perspective, the tick of a clock lasts 1 second, making it possible to blink 3 times during a single tick of a clock.

How fast is a fraction of a blink?
Human adults blink approximately 12 times per minute and one blink lasts about 1/3 s [2].
