When was blinking invented? and how many times do you blink a minute?

You blink 15-20 times a minute without even thinking about it, which is equivalent to about 1200 blinks an hour. So, why do we blink? Blinking is essential for healthy vision for two main reasons: foreign debris removal and eye lubrication. On average, a person blinks every 4 seconds depending on how long they are awake, or about 15 times per minute, or more than 20,000 times a day. Each blink lasts about a tenth of a second, not much. However, it is enough to clean and lubricate the eye surface.

Mechanism of Blinking: Why does it happen?

Blinking protects your eyes from bright light and irritants such as propanethial oxide (the tear-causing substance in onions). Scientists have found that blinking can also help the brain to relax. Researchers in Japan used an fMRI machine to monitor brain activity in 10 volunteers. The researchers found that participants blinked at once while watching a TV show when comparing the results.

Next, the researchers tested their hypothesis and found that, contrary to popular belief, blinking was a predictable behavior, not random behavior people watching a movie or attending a meeting blink simultaneously. Researchers have also found that brain regions associated with arousal are activated when people blink. It turns out that all blinking is a way to relax so that the brain can process information around it.

When was blinking invented?

It is not known exactly. We can safely assume that blink was invented at some point. However, historically, it is impossible to determine exactly when this happened. Scientists estimate that early humans evolved about 2 million years ago to moisten their eyes. They believe it has been an integral part of human evolution. Most importantly, it has helped people see better under the hot African sun. It has seen the function of blinking to keep the eyes moist to protect them from dust and debris by spreading tears on the eye’s surface.

Why do we blink our eyes?

Blinking is a reflex result of the nervous system. When light hits the eye, the light-sensitive retina is activated. Stimulation from the retina travels through the optic nerve to a part of the brain called the hypothalamus. There are nerve cells that respond to both light and darkness. These cells send a message to the eyelids to close quickly. The blink response consists of two steps.

1. You close your eyes slightly to prepare them to close entirely in the first step. At this stage, the eyelid is gently pulled down by the levator muscle of the upper eyelid. Then the eyelid becomes stable by the orbital muscle of the eye. The orbicularis muscle is responsible for keeping the eyelids closed after blinking.
2. The second stage is when the eyelids are completely closed and stabilized by the ptosis (the gap between the two eyelids). People can suppress the blink reflex by focusing on another object or object that interferes with their vision.

Blinking in everyday life in different age groups

• Children

Babies do not blink at the same rate as adults. Babies blink an average of 1-2 times per minute. The reason for this difference is unknown, but we can say that infants do not need the same amount of eye lubrication as adults.

The reason is that their eyelids open less than adults. Also, during the first months of life, babies do not cry. Babies also sleep much more than adults, and, as discussed earlier, their tired eyes blink more frequently. However, the frequency of blinking increases in childhood and adolescence is generally the same as in adults.

• Adults

Studies of gender-related [suspicious-discussion] differences in blink rate have yielded mixed results. Results ranged from nearly twice the blink rate in women to no significant differences between men.

Additionally, women using oral contraceptives blink 32% more often than other women. Typically there are 2-10 seconds between each blink. Actual rates vary from person to person and average about ten blinks per minute in a lab environment.

Most importantly, when the eye focuses on an object for a long time, such as while reading a book, the blink rate drops to 3-4 times per minute. It is the main reason your eyes get dry and tired while reading. If your eyes become dry or tired while reading on your computer screen, it could be a sign of computer vision syndrome.

Diseases associated with eye blinking

You can prevent computer vision syndrome by taking regular breaks, focusing on objects away from the screen, in a bright workspace, and using a blink notification app. Studies have shown that biofeedback can help adults learn how to maintain a healthy blink rate while reading or looking at a computer screen.

Eye blinking can be a criterion for diagnosing a disease. For example, excessive blinking may indicate the development of Tourette’s syndrome, stroke, or a nervous system disorder. Reduced blink rate is associated with Parkinson’s disease.

How many times do you blink in a minute?

Blinking also helps with emotional times. When you cry, you blink more often to wash away your tears. It prevents creating lakes in the eyes that can blur your vision. Blinking is a reflection. Moreover, this process happens subconsciously, but you can also force your eyes to blink.

According to PaganDuran, it takes an average of 400 milliseconds for a person to blink. She added that most people blink 10 to 20 times a minute, usually about 15 to 16 times. However, some situations make people blink their eyes more or less often.

Final Thoughts

Blinking is a very natural act for us humans. However, it is not known the origin of blinking. There are several theories on the origin of eye blink. Some say it was in early humans, and others think it was hereditary. But all mammals blink, so this must have been a long time ago. We can only guess about the beginning of the blinking process but it must have been necessary for primitive man. Blinking is important for protecting your eyes in addition to a few other functions.
