There are more reasons for frequent tearing of the eyes, such as tear duct obstruction, viral conjunctivitis, keratitis, corneal foreign body, etc. 1. Lacrimal duct obstruction: When the lacrimal duct is obstructed, the flow of tears is blocked, leading to the symptoms of tearing. Patients can undergo tear duct flushing or tear duct exploratory surgery to unblock the tear ducts, thus improving the symptoms of frequent tearing. 2. Viral conjunctivitis: When viral conjunctivitis occurs, under the stimulation of inflammation, the patient’s eye secretion will increase, and there may be photophobia, tearing and other uncomfortable symptoms, the patient can follow the doctor’s instructions to use antiviral eye drops for treatment, such as ganciclovir eye drops and so on. 3. Keratitis or corneal foreign body: When there is inflammation of the cornea or foreign body, the patient can manifest as tearing, photophobia and foreign body sensation. It is recommended that patients with frequent tearing and other discomforts consult a doctor to evaluate their condition and follow the doctor’s instructions for treatment.
