Did you know that the Guinness Book of Records has a page dedicated to eye muscles?
In this way, they decided to reward them for their hard work.
Yes, yes, the most active muscles in the human body are the eye muscles, of which each eye, by the way, has six.
Let's give an example: during one hour of active work with text, the eyes have to make about 10,000 movements.
This, by the way, is twice the number of heartbeats during the same period.
The eye muscles are constantly in tone to control the eyeball: to hold it in place, to turn it, or to make micro-movements for coordination.
Another interesting fact is that in both eye sockets these muscles work synchronously.
However, there are also cases when a person can turn only one eye towards the bridge of the nose, but all of them require considerable skill.
