After a cold, the patient’s eyes are sore and watery, which may be caused by a bacterial or viral infection in the eyes after a cold. If the patient’s eyes are infected by bacteria or viruses after a cold, such as bacterial conjunctivitis, keratitis, etc., under the stimulation of inflammation, the patient may experience discomfort such as soreness and tearing of the eyes, as well as an increase in ocular secretions and other discomforts. Some patients are prone to ocular inflammatory lesions due to poor immunity after a cold, which can irritate the patient’s eyes and lead to discomfort such as sore and watery eyes after a cold. It is recommended that patients with sore, watery eyes and other discomforts consult a hospital in a timely manner to assess their condition and follow the doctor’s instructions for treatment.
