(HealthDay News) — The eye produces tears to help it stay lubricated and to get rid of irritants. Watery eyes occur when too many tears are produced, or the tear ducts don’t drain properly.
The U.S. National Library of Medicine says here are some possible causes of watery eyes:
- Allergens such as dust, mold or dander.
- An inflamed eyelash follicle (blepharitis).
- A blocked tear duct.
- Conjunctivitis, an infection of the membrane that lines the eyelid.
- Exposure to an irritant such as polluted air, dust or bright light.
- An eyelid that’s turned improperly.
- An irritation or scratch.
- An eyelash that grows inward.
- Straining the eyes, laughing or yawning.
