Humans are good at telling whether another person is looking at them from a distance.

When you catch someone looking at you, what makes you feel their watching? Often, it's the position of the person's head or body. If both his or her head and body are turned towards you, it's clear where the person's attention is focused (集中). It's even clearer when the person's body is pointed away from you but his or her head is facing you. When this happens, you immediately look into the person's eyes to see where he or she is looking.

Human eyes are different from those of other animals. Our pupils (瞳孔) and irises (虹膜) are darker than the white part of the eyeball known as the sclera (巩膜). This is why we can know it when someone is looking at us or simply looking past us. We evolved (进化) to have larger white scleras which help us make eye contact. However, animals don't want the animals that they hunt to know where they're looking, so their eyes are different from ours.

But when head and body positions don't provide much information, research shows that we can still know another person's long look well. Clifford, a researcher, tested this by asking people to point out where different eyes were looking. He found that in situations where we weren't sure where a person was looking, our brain told us that we were being watched.
