Introduction
Having one single eyelid and one double eyelid may result from differences in eye structure, natural growth changes, underdeveloped eyelids during infancy, allergic dermatitis, conjunctivitis, or other causes. Correction can be achieved through methods such as double eyelid surgery (blepharoplasty), canthoplasty, eyebrow lifting, or medical treatment under a doctor's guidance. It is recommended to visit a reputable hospital and undergo these procedures under the supervision of a qualified physician.
In general, having one single eyelid and one double eyelid may be caused by differences in eye structure, natural aging changes, poor eyelid development during infancy, allergic dermatitis, conjunctivitis, or other reasons. Correction can be achieved under a doctor's guidance through methods such as double eyelid surgery (incision method), canthoplasty (eye corner lift), brow lift surgery, or medical treatments. Specific analyses are as follows:
1. Differences in Eye Structure
Everyone has individual variations in eye anatomy, including eyelid thickness, distribution of muscles, and degree of fat padding. These differences may make it easier for one eye to form a double eyelid crease while the other finds it more difficult. It is recommended to maintain good eye hygiene, avoid eye strain, and perform regular eye exercises. Under medical guidance, double eyelid surgery (incision method) can also be performed, which creates a stable fold in the upper eyelid skin to convert a single eyelid into a double eyelid. The typical reference cost for double eyelid surgery ranges from 3,000 to 9,000 yuan per session. Improvement is usually visible within 2–3 weeks after surgery, although potential side effects may include infection or scar hypertrophy.
2. Natural Aging Changes
With age, the skin around the eyes may become looser. One eyelid may gradually droop due to gravity, resulting in a single eyelid, while the other may retain its double eyelid due to better muscle tone and skin elasticity. Maintaining a healthy lifestyle and avoiding excessive eye use is recommended. Additionally, under a doctor’s advice, canthoplasty (eye corner lift) may be used to improve appearance by surgically elevating the position of the eye corners, enhancing eye contour and aesthetics. The typical reference cost for canthoplasty ranges from 5,000 to 9,000 yuan per session. Improvement is generally noticeable within 1–2 weeks post-surgery, though possible side effects include bleeding and pain.
3. Poor Eyelid Development During Infancy
During infancy, eyelid development may be affected by various factors such as genetics and nutrition, potentially leading to underdevelopment in one eyelid and resulting in one single and one double eyelid. It is important to prevent eye injuries and perform regular eye exercises to promote healthy development of the eye area. Under medical supervision, a brow lift procedure may be considered. This involves removing excess skin and tissue from the brow or upper eyelid to lift the surrounding skin and improve eye appearance. The typical reference cost for a brow lift ranges from 5,000 to 12,000 yuan per session. Symptoms usually improve within 1–3 weeks after surgery, though side effects such as tearing or stinging may occur.
4. Allergic Dermatitis
Allergic dermatitis is typically triggered by exposure to allergens. It may cause swelling, redness, and itching in one eyelid, making the original double eyelid crease less visible or disappear entirely, thus appearing as a single eyelid. The other eye, unaffected by the allergy, may retain its double eyelid. Common accompanying symptoms include redness, itching, and stinging. It is recommended to follow medical advice and use medications such as Cetirizine Hydrochloride Tablets, Dexamethasone Acetate Cream, or Loratadine Syrup for treatment.
5. Conjunctivitis
Conjunctivitis is usually caused by infections from bacteria, viruses, or other pathogens affecting the conjunctiva. It may lead to swelling and congestion in one eyelid, turning a double eyelid into a single one, while the other eye remains unaffected and maintains its double eyelid. Additional symptoms include eye redness, swelling, and increased discharge. Treatment should follow medical guidance and may include prescription eye drops such as Levofloxacin Eye Drops, Acyclovir Eye Drops, or Ribavirin Eye Drops.
It is recommended to visit a reputable medical facility and undergo any procedures under the supervision of qualified professionals to ensure safety and effectiveness. In daily life, maintaining proper eye hygiene, avoiding contact with allergens and pathogens, and performing regular eye exercises are essential for preserving eye health.
