Eye wheals may be caused by not paying attention to eye hygiene, chronic inflammation, decreased resistance and other factors. 1. Not paying attention to eye hygiene: when not paying attention to eye hygiene in daily life and randomly rubbing the eyes, it may lead to repeated staphylococcal infections, thus triggering wheals. 2. Chronic inflammation: patients themselves suffer from chronic conjunctival inflammation and other diseases, which may also induce wheals. 3. Decreased resistance: In daily life, decreased resistance may result in the body not being able to resist the invasion of bacteria, but when the bacteria spread to the eyelids, wheals may appear. Patients are advised to consult a doctor for examination and use medicines such as erythromycin ophthalmic ointment and levofloxacin eye drops under the guidance of the doctor for treatment once granuloma appears.
