The human body has been designed perfectly. The coordination between all the organs and the connection between all the bodily systems, including nervous, respiratory, etc., has been made possible only with the brain’s most developed organ.
All the function that takes place is that blinking of the human eye is the most critical task carried out by our bodies. We do not schedule blinking, but our brain sends signals knowing that the eyeball needs to adjust to the varying lighting conditions and maintain the eye focus and not let the eyes go dry.
How Long Can We Go Without Blinking?
All the bodily functions that include eating, walking, and speaking are also called voluntary actions controlled by us and coordinated by the human brain.
The body also carries out many involuntary actions, which are not controlled by us rather than other organs.
For instance, eating is a voluntary action, but digestion is an involuntary action as we cannot control it in any circumstances. The human brain is the ultimate coordinator and the action taker; all the activities are performed under milliseconds carried out by the well-defined nervous system and the spinal cord in the human body.
Blinking the human eye is also an involuntary action, and it can be controlled but never stopped from doing so. For instance, eating is an action that can be prevented; internal and external factors can influence the blinking of the human eye.
Inner meaning that the action has to be taken and the brain will force to do so in every way; external factors are not closing the eye shutter and moving that to stay open done by the humans, to make the action possible will use the fool mechanism.
Meaning the brain will cause distraction and strain to the eye. The water will keep running, and the brain will temporarily disable the eye focus; the fool mechanism occurs after realigns certain hormones in the body.
Moreover, the blinking takes places of many required actions and not only focus of the eyeball to the light.
| Condition | Blinks Per Minute |
| Normal | 7 to 12 |
| Dusty | 18 to 23 |
| Excessive Light | 15 to 20 |
| Dry Conditions | 21 to 23 |
Why Can We Go So Long Without Blinking?
When talking about blinking our eyes, there are many factors to consider. Blinking is affected by one factor: the air conditions, the retina focusing on the light, the age group, and the water spreading.
Blinking of the eye is directly related to environmental factors. For instance, on a well-lit bright day, the human eye blinks at least 15 times in a minute as the eye cannot focus. The retina needs to adjust that is done with blinking; moreover, on a windy day, the blinking takes places excessively as dunes or particles represent in the air that gets son the eyeball by blinking, the dust particles are flushed out.
Age group also adds to the blinking as in children the eyes are perfect and the brain doesn’t have to adjust a lot so comparatively children blink less than adult and older adults, a new born baby blinks only twice in a minute. As we grow old, the eyes become weak, and adjusting is hard, so the older adult blinks constantly to adjust to the conditions.
The human eyes need to have a little water content or fraction of water in the eye, as the water is a protective layer and catches the dust particle and flushes out the particle. Simultaneously, weblink blinking helps in equal spreading of water in the eyes, the water extracted from the tear glands.
Therefore, many external factors play a significant role in blinking our eyes and the action is carried out by the human brain through a well-defined nervous system.
Conclusion
All human body actions are coordinated and controlled by the human brain, whether voluntary or involuntary. Both external and internal factors cause automatic actions.
Where external being the environmental conditions and internal is the brain.
Blinking of our eyes is humans can control voluntary and, at the same time, involuntary actions as the blinking of our eyes by forcing the eye shutter not to be closed. In contrast, the brain uses a fool mechanism through hormones causing the human to blink.
Therefore, the brain plays a dominating role in blinking. Moreover, the eye’s blinking is not affected or controlled by only one factor, but there are more that are the air conditions, retina focusing to the light, the age group, and the water spreading.
