1, the eye distance is too wide According to the standard of “three chambers and five eyes”, the distance between the two inner corners of the eyes is equal to the width of an eye, if the distance between the two eyes is wide, then it is time to open the inner corner of the eye, shorten the distance between the eyes. Doing double eyelid + open the inner corner of the eye, the eyes become larger, the eye shape also becomes slender and beautiful. 2, the eyes are not bright enough General eye exposure rate should be in about 95%, so that the eyes look divine. However, in many cases, the inner canthus and outer canthus are not exposed enough. In this case, if you want to have bright eyes, you have to do double eyelid + open the inner and outer eye corners. Of course, in addition to the above two cases, those who prefer European-style big eyes can get them through double eyelid + open inner and outer eye corners. Physiological structure needs Because Asian people have some inner canthus, only the severity is different, it will cover the inner part of the eyes, the eyes do not look small, but look very, very small! If your eyes are class 2 or class 3, it is very necessary to have an eye opening surgery.
