In most cases, eyes with a single eyelid make an eye seem so small in both of width and length, They look closed and heavy. Therefore, the refined image is hardly made and they always cause the eyes to look swollen and small as if the person is unintentionally glaring.

Outline of the eyeline with a double eyelid

The eyelashes are the true boundaries of the eyeline between the eyelid and the cornea of the eye (the black region of the eye.) The eyeline of a Caucasian is exposed almost completely and it is appeared to look clear and pure due to sufficient exposure of the cornea.
Also, the eyes look bigger because of the higher location of the line of the eyelid.
In contrast, eyes of a Korean with only a single eyelid are covered with sufficient amount of skin drooping down from above.
Therefore, the eyeline where the lahes grow is hidden within the skin instead of showing the real eyeline.
As a result, the more the eyelid skin droops down, the smaller and the puffier the eyes look.
It also results in widened and exaggerated intercanthal distance due to existing Mongolian folds.
