If you have watery eyes and sore eyes, you should go to the hospital in time to be examined by an ophthalmologist to clarify the cause of watery eyes and sore eyes and treat them according to the cause. First, it is possible that a foreign body may enter the eye, and the foreign body may irritate the eye and cause pain, resulting in watery eyes. The foreign body in the eye can be removed by the ophthalmologist and treated with tobramycin drops as appropriate, which can eliminate the symptoms. Second, watery eyes and eye pain may be caused by infectious diseases in the eyes, such as conjunctivitis and keratitis, caused by bacterial or viral infections. When the eyes are sore and watery, use the appropriate antibiotic or antiviral eye drops according to the specific causative organism, treat the eyes with drops as prescribed by the doctor, and keep the eyes clean and pay attention to eye rest. Thirdly, watery eyes and eye pain may be caused by inverted eyelashes, with entropion, inverted or disordered eyelashes, which touch the cornea and cause stinging, grinding and watery eyes. Depending on the specific situation, treatment with electrolysis for inverted eyelashes or surgery for lid entropion and inverted eyelashes can be performed.
