Much meaning can be carried, clearly, with our eyes, so it is often said that eyes can speak. Do you have such kind of experience? In a bus you may look at a stranger, but not too long. And if he notices that he is being stared at, he may feel uncomfortable.

The same in daily life! If you are looked at for more than necessary, you will look at yourself up and down, to see if there is anything wrong with you. If nothing goes wrong, you will feel angry toward others’ stare（盯着）with you that way. Eyes do speak, right?

Looking too long at someone may seem to be impolite or even rude. But things are different when it comes to stare at the opposite sex. If a man look at a woman for more than 10 seconds and refuses to turn away from his looking, his purpose is obvious, that is, he wishes to attract her attention, to make her understand that he is admiring her.

However, the normal eye contact for two people during a conversation is that the speaker will only look at the listener from time to time, in order to make sure that the listener does pay attention to what his friend is speaking, to tell him that he is interested.

If a speaker looks at you continuously when speaking, as if he tries to control you, you will feel uncomfortable. We usually find a poor liar（说谎者）looking too long at the victim, because he believes that it is a sign of honest communication to look straight in the eye. Totally wrong!

In fact, continuous eye contact only happens between lovers, who will enjoy looking at each other gently for a long time, to show feelings that words cannot express. Obviously, eye contact should be done according to the relationship between two people and the proper situation.
