Many of the patients who come to our clinic need double eyelid repair, and most of them come because their double eyelids are too wide and unnatural. Many people don’t understand why Europeans have beautiful wide double eyelids while Asians have unnatural wide double eyelids. This is because Europeans and Asians head and face anatomical structure and morphology of the differences caused by, first of all, the difference in bone volume, we will find that the European head of the anterior and posterior diameter is significantly longer than the Asians, and the width of the face is significantly smaller than the Asians, which results in the depth of the European bony orbital is significantly deeper than the Asians, the bony orbital volume is larger than the Asians; in the eyes and the soft tissues around the eyes of the same case, the European eyes will be deep in the eyes, and the Asian eyes will be deeper in the eyes. European eyes are deep in the eye sockets and look very deep, no matter if he has double eyelids or single eyelids, under the effect of infraorbital shadows, they all show wide double eyelids. While Asians have shallow eye sockets, the volume of the bony orbits is smaller, so the eyeballs appear relatively prominent, usually the light is shone on the face from above and sideways, if the brow bone and forehead are not enough to protrude forward, the infraorbital shadows are not obvious, making the eyeballs appear prominent, in which case, the narrower double eyelids will look more natural, and the double eyelids that are too wide will make the eyeballs appear more prominent and more unnatural; secondly, it’s the difference in the soft tissues, the Asians The upper eyelid is thicker, from the lid margin to the eyebrow, the skin is from thin to thick, to make a wide double eyelid, usually part of the upper eyelid skin will be removed, and this part of the skin is the excessive part of the skin thickness of the lid margin to the thickness of the skin under the eyebrow, this part of the skin removal means that there is a big difference in the thickness of the skin when the skin of the lid margin is matched with the skin of the eyebrow to the suture, which leads to the thick and swollen skin on the blepharoplasty line, which looks unnatural, and affects the aesthetics. This is the reason why Asian overly wide eyelids are unnatural.
