Double eyelids

Common card · No. 371992

Double eyelids, is a type of the creased upper eyelid, is an upper-eyelid look divided by a visible crease. "Double" does not mean that a person has two anatomical eyelids, it refers to the external upper-eyelid surface divided by one crease. In anatomical text, the feature may instead be described as the presence of an upper-eyelid crease, palpebral fold, supratarsal fold or supratarsal crease. The levator palpebrae superioris muscle raises the upper eyelid through its aponeurosis, which attaches to the tarsal plate and surrounding soft tissues. A supratarsal crease forms when connections between the levator-associated tissues and the overlying skin cause the skin to be drawn inward as the eyelid is raised. An upper eyelid without a clearly visible supratarsal crease is commonly described as a monolid or single eyelid. In modern world, population with double eyelids constitute a larger proportion than those with single eyelids or other eyelid looks.
