Eye muscles are the busiest muscles in the human body.


In order for the brain to get a specific visual picture, the eye fixates and stops moving for a fraction of a second.

The more visual information the brain wants, the more actively the eye moves.

There can be as many as 400-500 mini-movements per second, but scientists estimate the average as two per second or about 173 000 per day.

Here are some typical eye movements made while scanning a face.


Compare this with the heart muscle. A heart rate of 80 beats per minute corresponds to 115 000 beats per day.

Thus, of the 639 muscles in a human body, the eye muscles are the busiest.
