Much information can be clearly sent just through our eyes, so the expression "eyes also talk" is often heard. Can you remember any experience that further proves this statement? On a bus you may quickly glance at a stranger, but not make eye contact. If he senses that he is being stared at, he may feel uncomfortable.
It is 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 at you that way. Eyes do speak, right?
Looking too long at someone may seem to be rude and aggressive. But things are different when it comes to staring at the opposite sex. If a man glances at a woman for more than 10 seconds and refuses to move his eyes, his intentions(意图) are 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 in 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 the former is speaking, to tell him that he is attentive.
If a speaker looks at you continuously when speaking, you will feel upset. A poor liar usually shows himself by looking too long at the other person, since he believes the false idea that to look straight in the eye is a sign of honest communication.
In fact, continuous eye contact is common only for lovers, who will enjoy looking at each other tenderly for a long time, to show love that words cannot express.
Evidently(明显地), eye contact should be done according to the relationship between two people and specific situation.
