? And the vast majority of orientals are single eyelids? Many people don't understand this. Let Dong Ping introduce it. When most orientals open their eyes, the skin of the upper eyelid droops to cover the eyeball, and the distance between the inner canthus is wide. Some people have more adipose tissue in their eyes, which makes their eyes look smaller than they really are, which also makes their eyes look dull. The height of the upper and lower diameter of the eye fissure is "the average person is less than 10 mm, and the ideal value is greater than 10- 12 mm". It is observed that almost all westerners have double eyelids, and the height of the upper and lower diameter of the eye fissure is about 12 mm, so it usually looks like westerners have big eyes. Necessity of eye surgery: about 1/2 Oriental people do not have double eyelids. Eye plastic surgery has become the most common cosmetic surgery in the east because of the aesthetic concept of double eyelids and the functional obstacles such as narrow vision caused by slack or false droop of upper eyelid skin. Morphological characteristics of eyes: Asian levator palpebrae muscle fibers become shorter or missing near the skin, which is the reason for the formation of single eyelids. Westerners' orbital septum fat, cheekbones, nose and other periocular bones protrude, resulting in deep eye sockets. Pull its surface fat, and the skin will easily form double eyelids. In addition, about half of the people have epicanthus, which is reflected in the angle between the inner canthus and the outer canthus. Oriental inner canthus is usually higher than inner canthus, which forms the so-called Mongolian inclination angle. Now you know why. Finally, Dong Ping, an expert, also reminds you that although double eyelid surgery is the most common operation in cosmetic surgery, it seems easy, but a slight negligence may cause lifelong pain to patients. Therefore, we must choose an experienced eye plastic surgeon in a regular hospital for surgery, thus greatly reducing the risk of surgery.
