The length of the eye tail may be caused by congenital genetic factors, local pigmentation or accumulation of fat particles. If one or both parents have eyes and tails, children will have a higher chance of having eyes and tails. If the length of the eye tail affects the beauty of the face, it can be improved by plastic surgery, and the beauty of the eyes can be adjusted to make the eyes look more harmonious and beautiful. During the treatment, do a good job in wound care, try to avoid wound infection, and don't eat spicy food.
