Why do stars always wear sunglasses?

Stars wear sunglasses not only to "play handsome and cool", but sometimes they may not want to reveal their identity. People always say that glasses are the windows to the soul, and people can judge your emotions, your joys and sorrows from your eyes. Stars live in the eyes of the public and are always watched. Whether they appear in airports, hotels or cinemas, they will be followed by reporters and fans. At this time, wearing a pair of sunglasses can effectively isolate all this, without eye contact with others, which can cover up the poor mental state and avoid fans' worry.

Besides, the biggest function of wearing sunglasses is not to let others recognize you. Although stars, as public figures, may not often appear around us, as individuals, they also need to have their own personal lives. They also need to go shopping to buy clothes and play with friends. At this time, wearing sunglasses can cover most of the face, travel more smoothly, and will not cause disturbance to the people, or even lead to social disorder and occupy public resources.
