It has been said that your face (especially your eyes) is the most expressive part of your body. give examples of eye movement, and explain what these movements usually mean.

Look up, down or sideways. Look to the side.  A quick look.  Eye contact . Blink rapidly

Explanation:

If the person looks down, this could be a sign of submission or even guilt. Looking down and to the left can indicate a person who speaks for himself. Looking down and to the right can show that you are feeling an intense emotion.

Looking to the side may indicate distraction or the search for a potential threat, but a sideways glance may also indicate irritation. In addition, eyes that look the other way often indicate cunning and lies.

A glimpse usually indicates a desire for something. Glancing at a door might show a desire to leave the room, while a glance at a person could indicate a desire to talk to her. A look is also used when it is forbidden or it is taboo to look at something.

Strong eye contact can mean that a person is paying close attention. It can also mean that the person likes you and respects you. When prolonged eye contact (gaze) occurs, it sometimes indicates aggression or power but can also show surprise or shock.

Rapid blinking of the eyes can occur when a person is thinking, and this can also be another sign of the lie.
