Mostly reaction to common triggers

Detailed Answer:
Hi
Thanks for your query.

There can be many causes of excessive watering of eyes.

Watering normally happens to clean the eyes. Otherwise it maybe due to causes like allergy, infection of eyes, blockage of duct connecting the eyes to nose, etc.

If this persists, its better to get examined by an eye specialist (ophthalmologist).
You can also let me know details of your symptoms like colour of discharge, duration, frequency, triggers, any other symptoms, etc and I can help narrow the diagnosis.

Hope it helps. Let me know if I can assist you further.
