The meeting of the eyes of two strangers is a common plot in romantic cinema. However, when we look into the eyes of another person, the most complex and unconscious reactions occur in our brain. Everyone can remember a moment in life when in a noisy and crowded room, you suddenly meet another person's attentive gaze. The rest of the world plunges into gray tones, as if fading away, while you and your counterpart for a moment united in a mutual understanding that you are looking at him, and he is at you. We all know this from our own everyday experience. Meeting with a gaze is extremely powerful: our eyes tell a lot about ourselves and eye contact with another person changes our impression of him. For example, visual contact with another person so captures our attention that for a moment we really stop being aware of what is happening around. In addition, when we meet with someone's gaze, many cognitive processes are immediately turned on in our brain, since we realize that we are interacting with the mind of another person. This makes us concentrate on the thought that we have another person in front of us with his own mind and outlook on things, from this realization sometimes it becomes uncomfortable. For example, people who, during communication, look us directly in the eyes, seem smarter, more conscientious and sincere. What they say also seems more convincing. If the eyes meet at close range, the pupils of people begin to move in unison. I believe that all of this proves the truth of the old adage that the eyes are the mirror of the soul. In fact, looking deeply into another person's eyes is very powerful. After all our eyes are the only part of the brain that is directly open to the world. When we look into the eyes of another person, then we get as close as possible to his soul
