Perhaps it is a condition where glands in the eyelids are not functioning normally,the best treatment for this condition daily lid scrubs combined with warm compresses. You can use baby shampoo for lid scrubs. In the shower, place the shampoo on your index fingers, close your eyes, raise your eyebrows (to stretch the skin on your eyelids) and scrub back and forth along your eyelashes for 3 to 5 minutes. The hot water in the shower helps to soften the plugged oils in the glands while the mechanical scrubbing with your soapy fingers removes the oils.
First, you can wear protective glasses when you go out. Second, you should not use dirty hands to rub your eyes. You should have your personal basin and towels.

Take it easy, eye watering is a natural phenomenon, perhaps it is because your eyes are too dry, and your eyes will automatically produce water to keep them wet. My advice is that you should drink more water, eat more vegetables and keep regular physical exercise as well as eye exercise. If things don't get better, visit a doctor.
