You're seeing water in your eyes (experiencing watery eyes, or epiphora) because of several potential reasons, most commonly related to issues with tear production or drainage.
Common Causes of Watery Eyes:
-
Excess Tear Production:
- Dry Eye Syndrome: Paradoxically, dry eyes often trigger excessive tear production as the body tries to compensate for the lack of lubrication.
- Irritation: Foreign objects (like dust, eyelashes), smoke, or chemical fumes can irritate the eyes, leading to increased tear production to flush out the irritant.
- Allergies: Allergens can inflame the eyes and trigger excessive tearing.
- Infection: Infections like conjunctivitis (pink eye) can also cause watery eyes, often accompanied by redness and discharge.
-
Blocked Tear Ducts:
- Obstruction: Tear ducts drain tears away from the eye and into the nasal passage. If these ducts become blocked (due to inflammation, infection, injury, or congenital issues), tears will back up and overflow.
- Narrowed Tear Ducts: Sometimes, the tear ducts are simply too narrow to drain tears effectively, causing watery eyes. This can be more common with age.
-
Eye Strain:
- Digital Eye Strain: Prolonged screen time can strain the eyes and lead to increased tear production.
-
Eyelid Problems:
- Ectropion: This is a condition where the eyelid turns outward, preventing tears from draining properly.
- Entropion: This is a condition where the eyelid turns inward, causing eyelashes to rub against the eye and leading to irritation and tearing.
-
Contact Lenses:
- Old or Torn Contact Lenses: Damaged or poorly fitting contacts can irritate the eye, causing it to water.
- Contact Lens Solution Sensitivity: Some people are sensitive to ingredients in contact lens solutions, which can lead to watery eyes.
What to Do:
- Identify Potential Irritants: Try to determine if there's a specific irritant causing the problem (e.g., allergens, smoke).
- Rest Your Eyes: If you've been looking at a screen for a long time, take breaks.
- Use Artificial Tears: Over-the-counter artificial tears can help lubricate dry eyes and reduce the urge to produce excess tears.
- Warm Compresses: Applying a warm compress to your eyes can help to unclog blocked tear ducts.
- See an Eye Doctor: If watery eyes persist, are accompanied by pain, redness, discharge, or vision changes, or if you suspect a blocked tear duct, consult an eye doctor (ophthalmologist or optometrist). They can diagnose the underlying cause and recommend appropriate treatment. This may include prescription eye drops, antibiotics for infection, or even surgery to correct tear duct problems.
