In life, some people, especially the elderly, love to tear, and whenever the weather is cold or windy symptoms aggravated, even regardless of spring, summer, autumn and winter, indoor and outdoor, two eyes teary, as if there is something sad, not only affect the beauty, but also affect life and work. What is going on here?
Under normal circumstances, part of the tears secreted by the human eye is evaporated and part is discharged through the tear system. Therefore, if there is excessive tear secretion or tear drainage system disorder, tears will not be evaporated or drained in time, which will cause tearing. The main causes of excessive tear production are: mental or foreign body reflex stimulation, the effect of certain drugs and certain eye diseases such as lid, conjunctiva and iris diseases.
Common causes of tear drainage system disorders include: atresia, absence, abnormal position or narrowing of the tear dots; narrowing and obstruction of the tear duct to the nasolacrimal duct, or inflammation of the tear sac, all of which can lead to tear drainage disorders and cause tearing.
Therefore, if the phenomenon of frequent tearing occurs, you should still go to the hospital for a careful examination to find out the cause of the right treatment.
