Lacrimation can be both physiological and pathological. There are many reasons why tears can flow, and if in some cases this phenomenon is completely normal, in others it requires close attention, and even treatment.

To understand in which cases it is worth taking tears into account, and in which you can ignore them, you need to understand the reasons for which they appear.

Why do we need tears?

First of all, it is worth disassembling the physiological component and indicate the reasons for which tears are quite normal. Normally, tears do not flow often, and this is not accompanied by pain, pain, blurred vision, severe sharp redness, itching should also not occur. Tears are protective reaction, and they are designed to cleanse the eyes of various debris, pathogens. It is also worth noting that this liquid provides trophic functions, is optically important, it disinfects the eyes and ensures their breathing.

Causes

In addition to emotional factors, sadness or joy, tears may well come up in the eyes with a strong wind, the gusts of which irritate the eye membranes. A sharp blow, especially to the nose, sharp pain can also cause involuntary lacrimation. Eyes begin to watery when dust, sand, various debris gets in, and this is also completely normal.They wash away debris that moves to the edge of the eyeball and is removed naturally.

If debris gets into your eye and your eyes watery, you just need to help the body and rinse it carefully to get rid of pollution. If this fails, you must urgently contact an optometristso that he removes the foreign body. If the tears began to flow with any natural irritation, and this does not go away, despite the fact that the irritating factor no longer affects the eye, need to see a doctor. Normally, lacrimation stops in a few minutes, it should not last for hours.

Also, eyes can watery from bright sunlight, from overvoltage - for example, during long work at the computer. In this case, it is necessary to reduce the load on the visual organs, to exclude the effect of bright light, to take breaks in work. After eye surgery, in the recovery period, intensified lacrimation can also be observed, which in the future will go away by itself. If it does not go away, you should also consult an ophthalmologist.
Smoke, vapors from onions, chemicals that also irritate the eyes and cause lacrimation can get in your eyes.

Tears with laughter, yawning and in a number of other cases appear due to the contraction of the lacrimal tubules, which occurs reflexively. If a person suffers from tearing from childhood, this may be due to genetics, or there may be anomalies in the structure of the lacrimal tubules or lacrimal sac.With inflammation of these organs, increased lacrimation may also occur, but not from childhood, but at some specific point, often accompanied by pain. If tears flow in the morning, this is normal., immediately after waking up, the body rinses the eyeballs and provides them with oxygen, because it was not enough at night, the eyelids were closed.

Pathological phenomena

Tearfulness also occurs in a number of diseases. This primarily concerns eye diseases, although there are other diseases that may be accompanied by a similar symptom. To understand everything in detail, it is recommended to consult a doctor.

Inflammation of the eyes and adjacent tissues often causes tears. Conjunctivitis and other similar diseases are expressed not only in the form of constant tears, but also in pain, severe redness of the eye. Glaucoma is expressed by increased intraocular pressure, and tears also flow with it. Inflammation of the eyelids, cornea, and even allergies to new cosmetics can cause tears, as well as discomfort and pain, itching.

Why are the eyes watering in older people?

With a decrease in the tone of the eye muscles in old age, similar problems can also be observed. Xerophthalmia, or dry eye syndrome, also develops in old age, and most often women suffer from it.

Other reasons

Often tears flow due to poor optics, improperly selected lenses. It is worth buying only high-quality lenses, without using them longer than the period for which they are designed.When using them, it is necessary to carefully observe hygiene standards and the rules for their use, otherwise unpleasant symptoms and diseases can occur.

And tears can leak due to any type of allergy, due to colds, such as SARS, ARI. With vitamin deficiency, with a deficiency of B2 or potassium, such a symptom is also observed. And in any case, if you suffer from severe lacrimation, which often manifests itself or does not go away for a long time, you should consult a doctor to find out the reasons.
