Watering of eyes can be due to many reasons and the main reasons are------------
1. Eye allergy due to dust, pollution, infection---------------
2. Weak eyesight------------
3. Continuous watching tv, mobile, computor in dim light----------
4. Any eye injury-------------
5. Lack of sleep-------
6. Continuous headache------------
7. Hypertension.---------------
so, my suggestion for you is either you provide me the symptoms you are facing due to watering of your eyes or visit a local doctor for an eye check up as a final examination can only be made after physical examination.-------------------
