What are the consequences of rubbing your eyes often?

Rubbing your eyes with your hands is very harmful. Children are active and their little hands are always dirty. Rubbing your eyes with dirty hands will bring some germs into your eyes, causing eye inflammation, and sometimes rubbing sand from your hands into your eyes. When playing with children with trachoma, rubbing their eyes with their hands can also cause the same eye disease. If one eye is red and itchy, rubbing it with your hands will infect the other eye. If foreign objects such as sand enter the eyes, rubbing your eyes with your hands is just like rubbing your eyes back and forth with a grinding wheel, which will cause epithelial damage of dark circles and even infection in severe cases. If your eyes itch, you can drop anti-inflammatory eye drops. When sand enters the eyes, it should be washed with anti-inflammatory eye drops first, and then go to the hospital for treatment. Never rub your eyes with your hands.
