Mosaic has brought great convenience to our lives (of course, it may be inconvenience) since its invention. It can be said that whether you are up to ninety-nine or just walking down, whether you are a financial expert on Wall Street in New York or a native African , have seen Mosaic.

Mosaic is used so widely, I don't know if you have noticed, where is the mosaic often hit?

Think about it carefully, you will find that the mosaic basically hits two parts:

Actually, there is some truth to this.

Eyes are a key feature of the face

Our face has several structures, from top to bottom are the forehead, eyes, nose, lips and face. Among these structures, the eyes are the most critical feature parts, because the eyes themselves are changeable, not only the difference in pupil color, but also the shape of the eyes, and the most critical eyes. Just like what everyone said, "give you a look and feel it yourself", the action of the eyes can convey many thoughts of the human body, such as joy and sadness, such as instruction information, etc. Therefore, some people say that the eyes are the windows to the soul [1].

Eye size remains relatively constant

I believe you must have a deep memory of children's big eyes, right? However, with the increase of age, it seems that the eyes are getting smaller and smaller. If you still have "a pair of beautiful big eyes" in adulthood, it is really a great appearance advantage. But this observation is actually wrong. Because the eye is a very strange organ of our body, that is, its size varies less. A baby's eyeball is 16 mm - 17 mm, and it is only 22.5 mm - 23 mm in an adult, and after the age of 13, the development is completed and remains unchanged, and the change is only about one-third. On the other hand, other parts of our body, such as height , increased several times from infant to adult. Therefore, the eyes of children are very large compared to the young body of children, but are small compared to the eyes of adults [2].

It is precisely because the eyes not only have obvious and diverse information, but also maintain relative stability, so people will choose to use the eyes as a standard of judgment when judging others. And once the eyes are covered, it is difficult for us to recognize this person, which is also the reason why mosaics hit the eyes.

Of course, it's the same reason for those celebrities to wear sunglasses when they go out, covering their eyes, except for hardcore fans, other people basically can't recognize them.
