This has happened to me before, all you have to do is go to sleep, or close your eyes and it will eventually go away. Is it located on your pupil? (black part of your eye right in the center) cuz if it is, you shouldn't touch it, but if it is located on the white part of your eye, or you can get it there, then with cledan fingers of course, you can lighty (with your finger,not nail) take it out
