Watery eyes can be due to one of two problems: either the eye is producing more tears than necessary, or the tear duct that drains the tears is not functioning properly. There are many possible causes for increased tears, which are a symptom in a majority of eye-related conditions and diseases. But once you find the culprit, treatment can be pursued. Causes of watery eyes can include:
1. Dry Eye Syndrome
2. Clogged tear ducts
3. Conjunctivitis
4. Environmental irritants such as chemicals, smog, hot wind, bright lights, blowing dust, and airborne allergens
5. Blepharitis
6. Abrasions
7. Foreign bodies
8. Allergies to mold, dust, and dander
9. Eyelids turning either inward or outward
10. Aging
