Watery eyes can be caused by many things such as allergies, bacterial infections, or even extreme weather. Here are some self-care steps that may be helpful in less serious cases:
- Avoid exposure to extreme weather without eye glasses or goggles.
- Limit screen time.
- Practice eye exercises.
- Take a break every few hours to rest your eyes.

Common remedies include washing your eyes, using eye drops, and using a warm compress . If you notice blurred vision, eyes watering for over a week, redness in eyes or bruising around the eyes, you should see a doctor. If you notice vision loss, blood or yellowish discharge from eyes, pain in the eye, swollen eyes or headache, you should see a doctor immediately.

I hope this helps!
