Watery Eyes: What Are The Causes?
The causes of watery eyes are varied, but in all cases there is, as the name indicates, excessive production of tears. As unusual as it may seem, sometimes more tear fluid is present than necessary.
The eye needs to be lubricated for optimal health, but sometimes tears find no way out due to an obstruction of the nasolacrimal duct; in this case they will have to come out through the eyelids.
Classification
We can classify this disorder based on age.
Watery eyes in babies
It is a very common condition, but it is best to pay attention to it to avoid annoying consequences. The causes in this case are often attributed to a small obstruction of the lacrimal canals or conjunctivitis.
It can also occur when the child has a cold, allergy or in the presence of a small lesion. If the lacrimation persists, contact the pediatrician who will clarify any doubts and prescribe a targeted treatment.
Although less frequently, this disorder can also affect newborns. Corneal changes are accompanied by profuse tearing and redness of the eyes.
Watery eyes in adults
In adults, the causes are different, although obstruction of the lacrimal canal continues to be the most common reason. Other associated disorders are:
- Eye fatigue, caused by excessive use of technological devices.
- Extreme dryness of the eye which, by compensation, stimulates the production of tears.
- Disorders related to aging.
Causes
Constant tearing can certainly be annoying also because it is generally accompanied by redness of the eyelids, irritation, swelling and burning of the eyes. It is important to trace the cause before starting a specific treatment, discarding the most serious complications.
Obstruction of the lacrimal canal
As we have said, the tears, produced by the lacrimal glands, have the function of keeping the eyes clean and lubricated. Any excess must flow through the tear channels that end inside the nose.
When the ducts become clogged, the tears have no escape and escape through the eyelids. At this point we experience a “cry” for no apparent reason.
Specialists call this condition dacryocystitis. It can be congenital or acquired and is characterized by a narrowing of the tear canals. In adults, the chronic form is linked to aging. The congenital form frequently affects very young children.
Dry eye syndrome
Dry eye syndrome is often due to a hormonal imbalance in women; another reason is the high rate of air pollution. Symptoms include burning, itching, photophobia, a feeling of dirty eyes and heaviness in the eyelids.
Although it is a consequence of a poor production of tears, this disorder manifests itself with watery eyes. This occurs because the glands work harder, as a protective mechanism.
Eye fatigue
Also known as asthenopia, this disorder falls under occupational diseases. It manifests itself with different symptoms, including watery eyes.
It is associated with the excessive use of electronic devices, a phenomenon that is increasing with the arrival of teleworking. This condition is classified under computer visual syndromes and can affect the ocular surface, causing severe tearing.
Conjunctivitis
It is one of the most common eye diseases. It affects all age groups and although it is very annoying, it is easy to treat.
Among the most common symptoms of inflammation of the conjunctiva (the imperceptible membrane that covers the eye) are: watery eyes, inflammation, redness and even discharge or accumulation of crusts in the corner of the eye.
Photophobia
Photophobia is a disorder characterized by the inability to withstand intense light, whether artificial or natural. Symptoms include excessive tearing, the need to keep the eyes closed, burning and redness. It can even cause nausea, dizziness, headache, and vomiting.
Other common and non-serious causes of watery eyes
In addition to the aforementioned ailments, watery eyes are often linked to allergies such as rhinitis, fever, laughter, yawning or even vomiting. In none of these cases is there to worry, as it is a reaction to an external stimulus.
Watery eyes: when should you go to the doctor?
When intense lacrimation is due to conjunctivitis, it is good to undergo a medical examination. It could, in fact, be a viral and contagious condition.
In addition, it is good to go to the doctor when the cause cannot be traced or when the disorder lasts for more than a week. The same is true if your eyes water frequently.
In any case, given the ease with which this disorder can be treated, it is advisable to go to the doctor in order to start the most suitable treatment. Excessive tearing not only lowers the quality of life, but also affects vision.
