Do not panic, man. You should know that panic can' t solve anything except add your fear. I know you may feel very uncomfortable. But never rub your eyes for now, trust me. There are two reasons. First of all, rubbing your eyes will get the contact lenses broken in your eyes. Secondly, it may get your lenses deep into your eyes which will add to the difficulty for u. I guess you don' t wanna this to happen. Wash your hands now. And get your eyes open in front of your family or your friends so that they find where the lenses are. And then take it out very quickly. On the contrary, if they still can' t find the lens in your eyes, then I can only suggest you to go to see your eye doctor right away.
