Why do my eyes water? Let’s be clear. When laughing or crying, it is absolutely normal. The tears flow because the tear ducts open. However, if the eyes start to tear without reason, a cause can be an eye condition.
There is no need to worry, as these problems can usually be solved quickly. Crying with joy, fear or anger, because of emotions , are normal human reactions. Tears also have a purifying effect.
There is an enzyme in their liquid that hinders bacteria and stops infections. Strong smells, such as that are exhaled by cutting onions, can also cause tearing. However, if the eyes, as mentioned, watery for no reason, the cause may be different.
Excessive or persistent eyes watery is a clinical ocular sign caused by different conditions. Alteration of the quality of tear film, for example, can occur as a result of pathologies such as conjunctivitis, eye lesions or other conditions that hinder the outflow of tears. The common causes of altered tearing are:
Blocked tear ducts
The most common cause of insufficient tear drainage among adults is partial or complete block of the tear ducts. If they are narrowed or blocked, the tears cannot flow out. Accumulate in the tear bag and become a cause of swelling (inflammation).
Stagnation of the tear fluid increases the risk of infection in the area. The eye reacts by producing a sticky secretion, further aggravating the problem. In addition, a defect in the tear glands can lead to the secretion of insufficient or altered tear volume. The effect causes dry eyes, which become more vulnerable to irritation and may not be able to fight infections.
Overproduction of tears
Any inflammatory stimulus of the eye surface (infections, allergies, foreign bodies or other irritants) can induce excessive tearing of the eyes. It is a defensive mechanism to eliminate irritating causes and protect the eye.
Watering disorders can occur at any age, but are more common in young CHILDREN (0-12 months) and people over the age of 60. Alteration of the tear film may affect one or both eyes and may cause blurred vision, edema of the eyelids and formation of scabs.
With Allergies excessive tearing is associated with itching and redness. Cold: It is very common for the eyes to tears with nasal congestion, sinusitis, viral infection of the airways. But also with recurrent cold and seasonal allergies. Conjunctivitis: excessive tearing is associated with redness, pain and secretion. Keratitis: excessive tearing is associated with photophobia , clouding or redness.
Dry eye syndrome
So, why do my eyes water and what is dry eye syndrome? Dry eye syndrome, is a pathology of the tear film due to reduced production or excessive evaporation of tears. Causes damage to the ocular surface and continuous stimulus to the production of tears.
It manifests itself in burning, foreign body sensation and can be diagnosed by the ophthalmologist by simple tests. With Sjogren’s syndrome excessive tearing can be an ocular manifestation of autoimmune systemic disease, such as systemic lupus erythematodes, rheumatoid arthritis, scleroderma.
Corneal abrasion: this is an abrasion of the corneal surface generally caused by a scratch or prolonged contact lens wear. Trichiasis: this is a deviation of the eyelashes that grow towards the inside of the eyelid.
Causing irritation and abrasion of the corneal surface. Foreign body in the eye (like a grain of dust, a splinter). Symptoms are discomfort, pain, severe tearing, redness, increased blinking.
Inflammation of the tear duct
Why do my eyes water with an inflammation of the tear drainage system? In one or both eyes, causes excessive tearing, and sometimes redness and secretion despite the absence of allergies, colds or other disorders.
In adults, the infection develops due to obstruction or narrowing of the tear duct. In newborns, it is a common condition and is the result of a still immature, narrow or closed tear duct. The tear duct may not be fully opened and functioning for several months after birth.
Ectropion: in the elderly, excessive tearing may be due to the lower eyelids, which tend to bend out. Causing the accumulation and release of tears. Eyelid defect closure: Failure to close the palebras often leads to problems with the cornea, with the possible cause of corneal infections and ulcers.
Contact with chemicals or irritants (shampoo, soap, cosmetics, household cleaners such as bleach, smoke, smog, dust). Some eye drops for ocular hypertension (especially in the first month of use).
Excessive tearing can be a temporary condition and resolve spontaneously. When it is the result of dryness of the eye or simple irritation of the eye, it is advisable to use artificial tears several times during the day.
These are eye drops that simulate the effects of tear fluid. If excessive tearing persists, an eye examination is necessary because specific therapies be required depending on the cause.
In the case of obstruction of the tear duct, surgical treatments may be required to clean the tear ducts, widen or reopen a closed tear canal. It is important to contact the ophthalmologist when excessive tearing persists and is associated with:
Sensation of something in the eye.
Redness, secretion, burning, itching or swelling that does not improve rapidly with the use of artificial tears.
For not pathological origin of this disorder, is recommended the use of non-invasive products. It is preferable to use eye wipes to clean the secretions or any external agents, and eye drops containing natural principles such as:
Hyaluronic acid that helps to moisten the corneal bag, maintain a constant level of lubrication of the eye and thus reduce the dry eye syndrome.
Calendula with soothing, astringent and antiseptic effect.
Chamomile with calming and soothing effect.
