Watery Eyes: Causes, Diagnosis, Treatment and Home Remedies
The watery eye, the epiphora or tearing, is a condition in which there is an overflow of tears on the face, often without a clear explanation, the tears keep the front surface of the eye healthy and maintain clear vision, but too many tears can hinder vision. Epiphora can develop at any age, however, it's far more common in those who are younger than one year or older than 60 years and might have an effect on one or both eyes.
Causes
Something in your eye
When something enters your eye (a speck of dirt, dust, an eyelash), your eye produces more tears to expel it. Even things that are too small to see, like particles in smoke or chemicals in onions, trigger this reaction. Once the problem is eliminated, your eyes will stop watering. But there are other health and eye problems that can also make you cry more often.
Dry eyes
You may have this problem because your eyes don't make enough tears, they dry too quickly, or they don't have the proper balance of water, oils, and mucus. Many things can cause these problems, from windy days to medical conditions. Whatever the cause, your eyes react by producing more tears.
Conjunctivitis
This is a common cause of watery eyes in both children and adults. It can make one or both eyes look pink or red and feel itchy and gritty like there is sand in them, the viral or bacterial infections are the most common cause. Viral infections don't need treatment, but you may need antibiotic eye drops if they are bacterial.
Allergies
Itchy, watery eyes often come with a cough, runny nose, and other classic allergy symptoms. Sometimes colds can also cause watery eyes, they won't itch. That's one way to tell the difference between colds and allergies.
Blocked tear duct
Normally, tears exit the tear glands above the eye, spread across the surface of the eyeball, and drain through ducts at the corner. But if the ducts become clogged, tears accumulate and the eye becomes watery. Many things can cause problems, such as infections, injuries, and even aging.
Overproduction of tears
Irritated eyes can produce more tears than normal when the body tries to flush out the irritant. The following irritants can cause excessive tear production:
- some chemicals, such as fumes and even onions
- an injury to the eye, such as a scratch or a bit of sand (a small pebble or a piece of dirt)
- trichiasis, where the eyelashes grow inward
- ectropion, when the lower eyelid is turned outward
Styes
They can lead to tearing in the eye, but the other symptoms are usually more obvious, such as a painful, red, swollen lump along the edge of the eyelid. Bacteria are the cause, and a stye will likely go away on its own in a few days. In the meantime, leave it alone and don't try to pop it like a pimple - it will spread the infection.
Eyelash problems
Have you ever had eyebrow hair that stubbornly grows at a strange angle? The same can happen with your eyelashes. If they grow inward instead of outward, they rub against the eye. It's called trichiasis, and it can occur after infections, injuries, or other problems.
Blepharitis
This condition causes your eyelids to swell, usually near the lashes. Your eyes may burn and be watery, red, itchy, and crusty. Many things can cause it, such as infections, rosacea, and allergies.
Treatment
Treatment depends on the severity of the problem and the cause. In mild cases, doctors may simply recommend watchful waiting or doing nothing and monitoring the patient's progress.
Different causes of watery eyes have specific treatment options:
-
Irritation: If the watery eye is caused by infectious conjunctivitis, the doctor may prefer to wait a week or so to see if the problem clears up without antibiotics.
-
Trichiasis: An eyelash that grows inward, or some foreign object that has lodged in the eye, the doctor will remove.
-
Ectropion: The eyelid turns outwards; the patient may need to undergo surgery in which the tendon that holds the outer eyelid in place is squeezed.
-
Blocked tear ducts: Surgery can create a new channel from the lacrimal sac into the nose. It allows the tears to bypass the blocked part of the tear duct. This surgical procedure is called a dacryocystorhinostomy (DCR).
- If the drainage channels, or canaliculi, inside the eye narrow but are not completely blocked, the doctor may use a tube to widen them. When the canaliculi are completely blocked, an operation may be necessary.
When to visit a Doctor?
Seek immediate medical attention if your eyes are watery with:
- vision loss or visual disturbances
- injured or scratched eye
- chemicals in your eye
- discharge or bleeding from your eye
- red, irritated, swollen, or sore eyes
- unexplained bruising around the eye
- tenderness around the nose or sinuses
- eye problems accompanied by a severe headache
- watery eyes that don't get better on their own
Watery eyes can clear up on their own. If the problem is due to dry eyes or eye irritation, using artificial tears or placing warm compresses on the eyes for several minutes may help. If the watery eyes persist, make an appointment with your doctor. If necessary, he or she can refer you to an eye doctor (ophthalmologist).
Home Remedies
Saltwater
Saltwater, or saline solution, is one of the most effective home remedies for eye infections. Saline solution is similar to tears, which is how the eye naturally cleans itself. Salt also has antimicrobial properties. Because of this, it stands to reason that saline can effectively treat eye infections.
Teabags
Putting cold tea bags on your eyes while they are closed can be a way to relax and unwind. Some say it can be an effective home treatment for eye infections.
Warm compress
A heat compress can help Warm compresses may soothe styes by reducing the blockages that cause the stye if the eyes are sore, infected, or irritated. They can also help relieve dry eye symptoms.
Cold compress
Like hot compresses, cold compresses do not exactly cure eye infections. However, they can alleviate the discomfort associated with certain eye diseases. Cold compresses can reduce swelling in the event of eye injuries and infections.
Honey
Some studies show positive implications for the use of honey eye drops to help treat eye infections.
