Eyelid swelling can be caused by both physiological and pathological reasons, and should be handled according to the different causes. Common pathological causes of eyelid swelling include blepharitis and blepharopharyngitis cysts. Excessive drinking before going to bed, late nights, and poor rest can cause physiological eyelid swelling, which can be relieved by regular work and rest, reasonable eye use, and avoiding excessive drinking before going to bed. Blepharitis is caused by bacterial infections of the eyelid glands and can be treated with antibiotic eye drops, commonly known as levofloxacin hydrochloride eye drops, or oral antibiotics such as amoxicillin and ceftazidime if symptoms are severe. Blepharoplasty is a non-specific inflammation of the blepharoplasty gland, which is self-healing and can be healed by applying hot compresses on the eye, if the cyst is large and does not subside for a long period of time, surgical excision is required. If the eyelids are swollen for no reason and cannot be relieved by resting for a long time, it is recommended to consult a doctor for examination to clarify the cause. The use of medication should be under the guidance of a physician, and should not be used blindly.
