Narrow eye is a common eye type in the east, which is relatively lacking in aesthetic feeling. Many people with small eyes and squints can't make their eyes bigger just by double eyelid surgery, because the corners of their eyes are too small, and even if they become double eyelids, their eyes will become smaller as a whole. This situation can be solved by opening the corner of the eye. By opening the inner (outer) corner of the eye, raising the corner of the eye and increasing the eyeliner, the eyes are bright and enlarged, and the spirits of the eyes are fully lit.
