Do you know, what is the speed of a blink? Maybe not, because normally we are not paying attention to an eye blink. It is a natural process and gets happens without information. When you pay attention to your blinking of an eye, then you will get an idea of how fastly you blink your eye. So, to make you aware of the speed of a blink, we are here with the article which provides all possible information regarding it. One thing I want to mention to you is that the speed of a blink may vary from person to person. Why? Below we will see it in detail. Let’s begin to learn about the speed of a blink.
The speed of a blink reached 243 ± 9 mm s-1 and 157 ± 5 mm s-1 during the closing and opening phase, respectively, whereas the average speed is 134 ± 4 mm s−1 and 26 ± 2 mm s−1, respectively.
On average the human blink lasts only a tenth of a second which is 100 ms. It’s really very fast and quick. Sometimes, it can even last up to 400 milliseconds. To put it into viewpoint, the tick of a clock remains for 1 sec, making it likely to blink 3 times during a single tick of a clock.
Is the blink of an eye faster than the speed of light? No, your eyelid does not travel faster than the light. The speed of a blink of an eye in mph is roughly about 13 mph and the speed of light is about 670, 616,629 mph, now you can see whether the comparison is valid or not.
How many blinks per minute? Normally, a person blinks his or her eye 12 to 15 times per minute. Do your eyes close when you blink? During a blink, your eyes close for a millisecond and you don’t experience it.
Now, you know what is the speed of a blink of an eye as well as the speed of a blink in mph. Let’s know about its calculation.
To calculate the speed of a blink you need to go through the eye blink speed test. In this, the blink rate is calculated.
The blink duration is measured in seconds and corresponds to the time difference between the start and end point of a blink. The interlink interval, also measured in seconds, corresponds to the time difference between the endpoint of a blink and the start point of the blink.
A blink is a temporary action in which a person closes his or her both eyes with the help of the upper and lower eyelids. Human adults blink approximately 12 times per minute and one blink lasts about ⅓ seconds.
Why do we blink? So, the blinking or a blink is important to maintain the integrity of the ocular surface and its characteristics such as blink duration and speed can vary remarkably, depending on the health of the eyes.
When you blink your eyelids clear away dust particles and press lubricating fluids across the eyeball. Every time you blink your eye sweep oils and mucus secretions across the surface to keep them from drying out. You don’t really notice the momentary darkness throughout the day that is created in a blink do you?
Now, the question is, is it safe to say that humans blink a lot? The person on average blinks his or her eyes for 15 to 20 times in one minute. And the average blinks per day is 19,200 times a day. How many times do you blink a year? In a year, a person blinks between 5.2 to 7.1 million times.

If you don’t blink, or don’t blink frequently enough: Your cornea can swell. Your cornea doesn’t have blood vessels, so it needs oxygen from the tear film, which it gets when you blink. If you simply blink less often, your cornea should still get the oxygen it needs.
Answer: 1.4204 x 10^-2 mph.
A blink is defined as ‘a temporary closure of both eyes, involving movements of the upper and lower eyelids’. Human adults blink approximately 12 times per minute and one blink lasts about 1/3 s.
Scientists have shown that the average person blinks 15-20 times per minute. That’s up to 1,200 times per hour and a whopping 28,800 times in a day—much more often than we need to keep our eyeballs lubricated. In fact, we spend about 10 percent of our waking hours with our eyes closed.
In this article, you have learned about a very small but also important action in the human body. It doesn’t mean only humans blink their eyes, all animals and birds also blink their eyes and everyone has a different rate. Above we have seen it for a human being only. Blink is necessary to lubricate the eye by replenishing the precorneal tear-film, it protects the cornea from dryness and cleans the corneal surface, shielding the eye from foreign objects such as dirt and dust, etc. now, you have understood everything about the speed of a blink.
