The eye cleft, or the cleft between the upper and lower lid margins. Narrower eye fissures can affect one’s facial aesthetics and can be improved in several ways: 1. Makeup: appropriate makeup can cover up the problem of narrower eye fissures, such as slightly lengthening the end of the eye, using false eyelashes, etc. 2. Blepharoplasty: Double eyelid surgery, which can be divided into the incision and buried line methods, makes a fold in the upper lid, which increases the eye fissure and makes the eyes more lively after surgery, and is suitable for people with narrow eye fissures that are This procedure is suitable for people with narrow eye fissures, “squinting eyes”, “triangle eyes”, “large and small eyes”, and “eight-eyed eyes”. If the candidate has a low nasal bridge, wide spacing between the eyes, small eye fissures and single eyelids, it is recommended to perform upper eyelid surgery plus rhinoplasty, which can lead to a greater improvement in facial appearance. Because the eyelids change a lot at a young age, the surgery should not be performed too early and is recommended to be performed after puberty. However, it should be noted that those who have a narrow eye fissure, overly prominent eyeballs, or narrow distance between the upper edge of the eyelid and the eyebrow are not suitable for this surgery. 3. Open outer corner surgery: This can be performed in conjunction with double eyelid surgery and can solve the problem of narrow eye fissures, but the surgery is relatively more traumatic and has more side effects, and there may be partial retraction of the outer lid margin after surgery, so you should fully communicate with a professional doctor before surgery to obtain the best results.
