Introduction
Persistent twitching of the lower eyelid of the left eye may be caused by physiological factors, inward-growing eyelashes (trichiasis), conjunctivitis, or other reasons. Factors such as fatigue, excessive eye strain, and lack of sleep can increase ocular stress or lead to local muscle fatigue, potentially causing aseptic inflammation. Under inflammatory stimulation, this symptom is likely to occur. It is recommended to rest adequately or perform appropriate eye exercises to help relieve the condition.
Persistent twitching of the lower eyelid of the left eye may be caused by physiological factors, trichiasis, conjunctivitis, or other reasons. A detailed analysis is as follows:
1. Physiological Factors
Fatigue, excessive eye strain, lack of sleep, and similar conditions may increase ocular pressure or cause local muscle fatigue in patients, potentially leading to aseptic inflammation. Under inflammatory stimulation, this symptom may easily occur. It is recommended to rest appropriately or perform eye exercises to help relieve the condition.
2. Trichiasis
Trichiasis refers to eyelashes rubbing against the eyeball or skin folds of the eyelid grazing the eye surface. Prolonged irritation from eyelashes can easily lead to eyelid spasms. Usually, maintaining good hygiene and timely trimming of long eyelashes can prevent this condition. In severe cases, surgical treatment may be considered.
3. Conjunctivitis
Conjunctivitis is a type of eye inflammation commonly caused by bacteria, viruses, parasites, and other pathogens. Inflamed conjunctiva may result in symptoms such as redness, swelling, and tearing of the eyes. Long-term stimulation by inflammatory factors may damage local nerves, causing this symptom. Treatment may include ophthalmic agents such as ofloxacin eye drops or erythromycin eye ointment, used according to medical advice.
In addition, this condition may also be related to blepharitis or other disorders. Once such symptoms occur, medical consultation is recommended.
