Tear of the eye is a very common problem, which most people do not attach much importance to. After all, the development of tears is a process that is carried out in the natural state in the body continuously.
Tears of, protect the conjunctiva (membrane) and the cornea of the eyes from drying out. About 1 ml is released per day. But what if the eyes begin to water too hard and often?
Why do people need tears?
Tears are called a liquid secret, secreted by tear glands located in the region of the frontal bone just below the eyebrows. Its main purpose is to protect the mucous eyes from drying out. The chemical composition of the tear fluid is very similar to the composition of the blood. An antibacterial substance called lysozyme contained in it, also contributes to the disinfection of the cornea of the eye and prevents the development of inflammation.
The transparency of the cornea and its ability to refract light largely depend on the quality of the tear fluid.
Due to the constant renewal of tears from the surface of the eyes, small dust particles are removed. The lacrimal fluid delivers to the cornea, which does not have blood vessels, and nutrients.
The eyes of are watered. and during a strong emotional experience: grief or joy. It is proved that in a tear fluid there are psychotropic substances that can suppress anxiety. It removes this fluid from the body and the hormones of stress of prolactin and leucine-enkephalin.
If a person is crying with laughter, both these substances protect the body from overexcitation, since they soften the effect of adrenaline.
When taking some medications or inflammation of the lacrimal tear sack, on the contrary, less can be released. In this case, not only the vision suffers, but the overall psychological state of a person changes.
At what illnesses and infections do the eyes water?
Excess tear fluid can appear as a result of various mechanical or toxic irritations or due to some diseases. Thus, lacrimation often occurs with infectious diseases: influenza, ODS, sinusitis, tuberculosis, syphilis, diabetes, general immunity decrease, etc.
It can appear and with blockage of ducts or other abnormalities in the activity of the lacrimal glands or canals that divert them. Since the normal operation of these organs is very important for the preservation of vision, with persistent lacrimation it is necessary to undergo a survey and identify the causes that cause their failure.
To diseases of the lacrimal apparatus are:
Irritation due to ingress of foreign bodies
When you get on the mucous hairs, large particles of dust or other litter, the body, trying to get rid of the foreign body, begins to produce a large number of tears. You can not rub eyes in this case, because there is a risk of damage to the cornea. It is necessary to carefully bring the garbage into the corner of the eye, and from there remove it. If you can not do this yourself, you should immediately call an ophthalmologist.
Irritation can be caused by an excess of ultraviolet rays, for example, after a long stay on the beach or visiting the solarium. Very dangerous is the burn of the cornea, for example, after welding. When it occurs, the eyes should immediately be treated with an antiseptic and turned to the hospital.

Why do my eyes water in the wind or in the cold?
Additional moistening of the eye's shell in strong winds is a natural reaction of the body. Thus, it protects the mucosa from drying out.
With a decrease in the temperature of the lacrimal canal located close to the surface, the flow of tears, which in the normal state goes into the nasopharynx, decreases. Instead, tears begin to surface. To reduce the reaction to frost in this case it is possible with the help of "training" of the eyes: contrast washings alternately very cold and hot water.
Some people have a reaction similar to an allergic reaction when staying in cold air. Just like when foreign antigens get into the body, the body begins to intensively produce histamine, which leads to the expansion of capillaries, which begin to press on surrounding tissues, causing their swelling. When the ducts are blocked, the tear sack overflows, and abundant lacrimation begins.
What drops to drip, if the eyes water?
To combat infection of the eyes, the following preparations may be used:
Five best folk remedies for watery eyes
For minor inflammation, you can use herbal extracts to reduce lacrimation:
Regular warm compresses of medicinal broths promote the expansion of lacrimal ducts and a better excretion of purulent discharge. The opening of the tubules is also helped by the massage of the lacrimal sac. To do this, with the index fingers for a few seconds, the dots in the corners of the eye are almost pressed down to the nose. The procedure should be repeated 3-5 times a day.
To what doctor to go and how to diagnose the cause?
Since lacrimation can be a sign of a variety of diseases that can lead to loss of vision, it is necessary to find out its cause. When visiting an ophthalmologist (oculist) - a doctor specializing specifically for eye diseases, it is necessary to describe in detail the symptoms associated with lacrimation. For example, if not only watery eyes, but there is pain in the nose, this may indicate the presence of dacryocystitis, and the combination of lachrymation with photophobia - the occurrence of uveitis or keratitis.
Examination of the eyes is carried out using a slit lamp. The doctor assesses the tone of the skin of the eyelid and the condition of the conjunctiva and the cornea. Next, we check the patency of the tear duct with the help of setting a color sample: the contrast agent is injected into the eye and it is checked how long it will appear in the nasal passage.
If there is a suspicion of stenosis (narrowing the lumens of the outflow channels), an X-ray with contrast agents is prescribed. After finding out the reason, medication is prescribed. In some cases, the obstruction of the canals can only be removed by surgery.

Vitamins for the eyes
Lack of certain vitamins in the body can also lead to lachrymation. In these cases, the intake of vitamins is prescribed:
To preserve the vision, both these vitamins must be present in the consumed food. So, vitamin A is contained in beef liver, cheese, carrots and all vegetables that have a dark green color. Vitamin B2 is most abundant in fish, liver, eggs, groats, nuts and tomatoes. Take care of and sufficient content in the body of vitamin C, strengthening immunity. In emergency cases, all these vitamins can be prescribed in the form of biological supplements to food.
How does sleep and nerves affect eye lacrimation?
General eye fatigue, lack of sleep and nervous stress can also provoke lacrimation. Specialized treatment is not required in these cases. It is enough to reduce the burden on the eyes elementary, regularly get enough sleep and avoid stress. A good help to tired eyes will be washing them with infusion of herbs that have anti-inflammatory properties.
Incorrectly chosen glasses or contact lenses can also cause eye strain.
The eyes of are watered. and with a strong migraine, arising from increased intracranial pressure. Treatment in this case should be aimed at eliminating these causes.
What can ignore the problem?
Even a small tear for a long time can lead to changes in the cornea and conjunctiva and, as a consequence, to a decrease in vision.
Severe pain and rapid reduction in visual acuity may indicate a ruptured retina or changes in the vessels, which can lead to complete blindness. Self-medication only worsen the situation. In these cases, you should contact the hospital at any time of the day or night.
