Uninvited tears are not as rare as they might seem. In windy weather with them many face. But there are a number of other reasons why an uninvited tear can roll out. Which ones – aif.ru told Candidate of Medical Sciences, ophthalmic surgeon, chief physician of the ophthalmological clinic Tatyana Fadeykina.
Tearing is a phenomenon in which the cavity between the eyelid and the eyeball is filled with an excess amount of tears, while tears literally begin to pour from the eyes, which causes discomfort. The main function of tears is not only regular moistening of the cornea, but also its protection (in case of irritation by a foreign body). Therefore, moisturizing the eye itself is a natural and necessary process for eye health. However, if the problem is not related to any of the other cases, then you need to understand the reasons for the excessive release of tear fluid.
Why can eyes water?
The release of tear fluid is a reflex function that occurs when possible damage to the eye, for example, when:
– strong wind, snow;
– smoke in the eyes;
– reactions to bright light;
– hit of a foreign body;
– strong odors/spices.
Lachrymation caused by external factors is easily treatable, the main thing is to remove the root cause, while there are also pathological reasons for the release of excess tear fluid.
pathological case
Problems with the outflow of tear fluid. This condition can be caused by chronic diseases of the nose (sinusitis, polyps, adenoids, rhinitis) or its injuries. In this case, the tear ducts are blocked or narrowed, and tears cannot enter the nasal cavity, accumulating in the eye. A similar situation is observed in winter, when the tear ducts are narrowed due to cold weather, obstructing the outflow of tear fluid.
Infection in the eyes. Excessive lacrimation can provoke infection through the tear duct. Also, a common cause of the problem is improper care and wearing of lenses. The presence of one infection can provoke the appearance of other problems, such as conjunctivitis (inflammation of the mucous membrane of the eye), keratitis (inflammation of the cornea) or blepharitis (inflammation of the edges of the eyelids), so it is very important not to wait until the problem goes away by itself, but immediately contact an ophthalmologist for help.
Mucosal inflammation also has such a common symptom as profuse lacrimation. In addition, the eyes often swell and become red. In the case of bacterial conjunctivitis, purulent discharge is often added.
Inflammation of the edges of the eyelids also often accompanied by discharge of fluid from the eyes. The disease impedes the outflow of the lacrimal canal, the eyelids swell, which leads to tearing.
Allergy. Direct contact with an irritant often causes inflammation of the conjunctiva, which is accompanied by severe lacrimation. Such a reaction can be to an animal, flowering, household chemicals or cosmetics.
Excessive eye strain. With eye fatigue or a situation where you have to peer / strain your eyes, lacrimation occurs as a natural reaction to an increased load. The reason may also be improperly selected glasses or lenses, as a result of which the eye is subjected to a large load.
Foreign body in the eye. A foreign object that has entered the cornea or conjunctival cavity usually causes severe tearing. Thus, the eye starts a protective function in order to wash the foreign body with the help of a liquid. As a rule, an irritating factor is an eyelash (including extended) or a mote.
