Ptosis is a common ophthalmic disease, characterized by the position of the upper eyelid margin being lower than the normal range, which may partially block the pupil and affect vision and appearance. Many patients complain of heavy eyes, limited visual field, raised eyebrows, and other problems, and then develop symptoms such as facial fatigue and even headaches. In recent years, more and more studies have begun to focus on the potential connection between ptosis and eye fatigue , exploring their cross-causal relationships, overlapping clinical manifestations, and mutual influence mechanisms.
1. Classification and causes of ptosis
Ptosis can be divided into two categories according to its cause: congenital and acquired.
Congenital ptosis is often caused by hypoplasia of the levator palpebrae superioris muscles.
Acquired ptosis can be divided into neurogenic (such as oculomotor nerve palsy), myogenic (such as myasthenia gravis), aponeurotic (such as relaxation of the levator palpebrae superioris aponeurosis associated with aging), and mechanical (such as tumor or trauma).
Among them, aponeurotic ptosis is more common in middle-aged and elderly people , manifested as mild ptosis of one or both eyelids, and the symptoms become more obvious as fatigue worsens.
2. Definition and clinical manifestations of eye fatigue
Asthenopia refers to an eye discomfort syndrome caused by long-term use of the eyes. It is common after close visual activities such as reading, using a computer or browsing a mobile phone. The main manifestations include:
①. Sore and swollen eyes
② Dryness
③. Burning sensation
④ Blurred vision
⑤. Decreased attention span
⑥Deterioration of sleep quality
Some patients may also experience heaviness in the eyelids and increased blinking frequency.
The core mechanism of eye fatigue is the continuous tension of the ciliary muscle and the instability of the tear film, which leads to ocular surface interference and visual system fatigue.
3. The association mechanism between ptosis and eye fatigue
1. Interaction between anatomical structure and functional burden
The levator palpebrae superioris and the frontalis muscle work together to maintain the open and closed state of the eyelids. When the eyelids are slightly droopy, patients often unconsciously raise their eyebrows to maintain a normal field of vision , which increases the burden on the frontalis muscle, causes forehead tension and head fatigue, and indirectly causes increased eye fatigue.
2. Visual distractions increase the burden of adjustment
Drooping eyelids block part of the field of vision, affecting the visual fusion and accommodation functions of both eyes. In order to maintain clear vision, the ciliary muscles need to continue to contract , causing visual fatigue and the risk of worsening myopia.
3. Eyelid weight bearing and blink dysfunction
Drooping eyelids may affect the normal blinking frequency and integrity , resulting in uneven distribution of tear film, inducing dry eye symptoms, and aggravating ocular surface discomfort and fatigue.
4. Clinical Observation and Case Analysis
In clinical practice, some middle-aged and elderly patients complain of "tired eyes" and "always wanting to close their eyes", which is actually caused by mild to moderate ptosis. Upper eyelid function examination and slit lamp observation can reveal eyelid displacement caused by decreased tension of the levator palpebrae superioris muscle or relaxation of the aponeurosis .
For example, a 60-year-old female patient complained of worsening eye fatigue in the past six months, especially in the afternoon. Examination revealed mild drooping of both eyelids, obvious elevation of eyebrows, and increased forehead wrinkles. After surgery to repair the position of the upper eyelid, the subjective fatigue was significantly relieved and the reading time was significantly extended.
V. Treatment and Intervention Measures
The method of treating ptosis is mainly determined by the cause. Common methods include surgical correction, physical training and adjustment of eye habits. For those with combined eye fatigue, comprehensive evaluation and multi-faceted intervention are required.
1. Surgical treatment (such as levator aponeurosis plication)
Suitable for patients with moderate to severe ptosis that affects visual field or causes facial fatigue.
2. Visual behavior adjustment
Reduce the time you use your eyes at close range, take a break every 30 minutes, and use the "20-20-20" principle: look 20 feet away for 20 seconds every 20 minutes.
3. Dry eye management
Appropriate use of artificial tears and improvement of blinking habits can alleviate the problem of tear film instability caused by ptosis.
4. Facial muscle relaxation training
Through massage and hot compress, the long-term tension of the frontalis muscle, orbicularis oculi muscle, etc. can be relieved, and facial and eye fatigue can be reduced.
VI. Prevention recommendations and daily management
①. Maintain a regular work and rest schedule to reduce excessive damage to eye muscles caused by staying up late;
②. Eat a balanced diet, supplement vitamin A, B group and other nutrients to maintain muscle and nerve function;
③. Use light sources appropriately to avoid reading in strong light or dark light;
④. Have regular eye examinations, especially for those with a family history of ptosis or those who use electronic devices for a long time.

There is a multi-level interactive relationship between ptosis and eye fatigue. Although the two are caused by anatomical abnormalities and visual behavioral burdens respectively, they highly overlap in clinical manifestations and development paths. Scientifically judging the source of fatigue and rationally intervening in the state of the eyelids are of great significance to improving visual function and enhancing the quality of life.
Eye health is not only related to appearance, but also directly affects visual efficiency and brain cognitive ability. It is recommended that the general public increase their awareness of ptosis. When persistent eye fatigue occurs, it is necessary to consider whether there are anatomical changes and seek medical evaluation and treatment in a timely manner.
