Don't every mess with your eyes! Piercings can be fixed, or left alone to heal, but your eyes are something altogether different.
I had a detached retina a few years ago, and it progressed so far that my vision is kinda messed up and I have a permanent silicon buckle under the iris. Your eyes are way too precious...don't **** with them.
Of course, recreational drugs are legal in the Netherlands, so that should explain a lot.
