People tend to express themselves by shedding tears when they encounter emotional stimuli such as joy or sadness. However, if your eyes are always tearing, you should consider that there may be adverse factors causing it, mainly tear duct disease, abnormal tear spot location, eyelid laxity, eye inflammation, dry eye, etc.: 1. Tear duct disease: tear duct obstruction or narrowing is the most common cause of frequent tearing. The narrowing of the tear duct or complete blockage of the tear duct due to disease or age and other factors can lead to the inability of tears to enter the nasolacrimal duct, resulting in the phenomenon of tear overflow. Patients need to go to the hospital for tear duct flushing or tear duct exploratory surgery, and serious cases need to undergo tear duct placement; 2, tear point location abnormal: if the tear point is not in the eye or there is an ectropion, tears can not be discharged through the normal, there will be the problem of tear overflow; 3, lax eyelids: many middle-aged and elderly people to a certain age will appear lax eyelids, lax eyelids will be more tears than normal people, eyes 4. Eye inflammation: If the patient has a combination of eye inflammation, such as conjunctivitis, keratitis, impingement, etc., the eye will be stimulated, resulting in an increase in reflex tears, leading to frequent tearing. Clinical symptomatic treatment is needed to relieve the phenomenon of watery eyes, for example, the extraction or surgery of impingement, and the anti-infection treatment for patients with conjunctivitis or keratitis; 5. dry eye: at present, due to the massive use of cell phones, computers and other electronic products, it is easy to trigger dry eye, which leads to the problem of easy watering; 6. excessive secretion of secondary tears: for example, when stimulated by physical or chemical stimulation Or when stimulated by emotional factors, the symptoms of increased tearing can also occur, but usually does not last too long and can be relieved after removing the trigger. However, certain systemic diseases, such as Parkinson’s disease, can lead to increased tear secretion paradoxically, resulting in the phenomenon of constant tearing.
