Tear production (also known as lacrimation) is an important process that occurs in the human eye. This process involves the production and secretion of tear fluid, which helps protect and moisturize the eyes.

Tears play a key role in protecting the eyes from various influences such as dust, dirt, infections, etc. They also help remove irritants from the eyes and prevent them from drying out.

Tears are not released only in response to irritating substances, they are released constantly. Normal tearing occurs several times during the day, usually without much sensation. However, if tears are produced too much or, conversely, too little, this may indicate the presence of various diseases.

Tear fluid is produced by special glands that are located in the upper outer part of the eyelids. After production, the liquid enters the lacrimal openings, which are located in the corners of the eyes. From there, the fluid flows into the lacrimal canals and further into the nasopharynx. Therefore, with strong lacrimation, a person may develop a runny nose, and with nasal congestion, the number of tears may increase.

Some conditions, such as conjunctivitis, dry eye syndrome, or blocked tear ducts, can cause excessive or insufficient tear production. If you have such symptoms, you should contact an ophthalmologist who will conduct an appropriate examination and prescribe treatment.

In conclusion, tear production is an important process that helps protect and moisturize the eyes and keep them healthy. If any disturbances in tear production occur, you must contact a specialist in order to promptly identify and eliminate the cause of the problem.
