Pinkeye refers to wheal or blepharitis. Frequent growth of wheal may be related to eye hygiene, prolonged wearing of contact lenses and eye diseases. 1. Poor eye hygiene: usually do not pay attention to eye hygiene, use dirty hands or unclean handkerchiefs and towels to rub the eyes. This leads to outside dust, germs and bacteria entering the eyes, causing frequent infections of the eyelid glands and leading to recurrent episodes of wheals. 2. Wearing contact lenses for a long time: contact lenses are covered on the cornea, which is easy to carry bacteria and should not be worn for a long time. If you wear contact lenses for a long time every day without paying attention to the cleaning of the lenses, it is also easy to cause the recurrence of granuloma. 3. Eye diseases: If the patient himself suffers from trachoma, chronic conjunctivitis and other eye diseases, the resistance of the eye will be reduced, unable to resist the infection of pathogenic bacteria. Bacteria can travel up to the glands of the eyelids, leading to recurrent wheals. When frequent wheals, it is recommended to consult a doctor in time, follow the doctor’s instructions and then further relevant examination, with the help of the doctor to clarify the cause, and targeted treatment or treatment.
