Putting too many foreign objects in your eyes

Continuously putting things like pencils and hairbrushes in your eyes while you have your contacts in may also prove to be very painful. Washing your contacts with other liquids such as sweet tea, shaving cream, or bleach is also almost certain to cause mild irritation as well. As long as you stay away from these actions, you should be alright.
