What causes tears and pain in the eyes

Under normal circumstances, the lacrimal glands in the human eye structure can secrete a small amount of tears, which can ensure the lubrication between the eyeball and the cornea and prevent the evaporation of tears from causing dryness of the mucous membrane. If you usually have symptoms of tears and eye pain, it is generally related to the influence of adverse external factors, such as cold air. Of course, diseases that hinder tear excretion cannot be ignored. In addition, chronic inflammation of the eyes can easily induce such symptoms.

1. Influenced by external factors

Some patients may secrete tears reflexively due to external stimulation of the tear glands, such as cold air or wind, resulting in increased tearing. Excessive tears cannot be discharged from the tear duct in time and flow out of the eyelids, causing tearing.

Treatment: This is purely a physiological tearing phenomenon. If the external stimulation factors are removed, this symptom will disappear, so no treatment is needed.

2. Tear drainage disorder

The tear secretion volume is normal, the tear duct is unobstructed, the flushing is unobstructed, but the orbicularis oculi is loose, the tear pump function is weakened or disappears, causing tear discharge obstruction and tearing.

Treatment: This case is functional tear sac mucosa, and the tear drainage function should be strengthened.

3. Chronic eye inflammation

Eye problems such as conjunctivitis, trachoma, trauma, foreign bodies, tumors, etc. can cause the tear duct to be narrowed, the tear duct to be incompletely blocked, and the tear drainage function to be reduced. The normal amount of tears secreted cannot completely flow into the nasal cavity and flow out of the eyelids, resulting in tearing.

Treatment: This situation is organic tearing, and tears will occur even indoors. You should go to the hospital for treatment in time.
