The Asian Eyelid differs greatly in both appearance and anatomy from the Western eyelid. Furthermore, there is great variability in appearance of the upper eyelid among people of Asian heritage. At first glance, the upper eyelid either has a prominent upper lid crease (or fold) commonly known as a “double eyelid” or it does not, a “single eyelid.” On the left is a single eyelid and on the eye on the right has double eyelid.
However, on closer examination there is actually a high degree of variability even among people with a “double eyelid.” The crease itself can be located at different distances from the eyelash line—ranging from 1-2 mm in some Asians to as high as 10 mm in some Caucasians. In the images [above] the size of the double eyelid increases from not present (single eyelid) on the left to about 10 mm (the Caucasian eye).
