Double eyelid refers to the skin of the upper eyelid, and there is a shallow groove above the eyelid margin. When you open your eyes, the skin under this groove moves upward, while the skin above this groove hangs loosely at the double eyelid groove and folds down. To form a pair of beautiful double eyelids, we must comprehensively consider the shape and width of double eyelids, the swelling degree of upper eyelids, the width of eyelid cleft, the radian of eyelid margin, the ratio of eye height to eye width, the distance between eyebrows and eyes and other factors.
From an aesthetic point of view, the size of the eyes and the size of the face depend on a certain proportion. If the width of face is 10cm, then the ratio of eyes is 2: 2.5, the length of eyes is 3 cm, and the width is 1 cm. The distance between the eyes is equivalent to the length of the eyes, which is the most ideal eye.
