Wow, slightest thing goes wrong there, they’re pretty much completely fucked. Looks like it could be kind of cool though.
No, it wouldn’t be cool… ever had a fruit fly in your eye? This would be like that, except it’s permanent and a hell of a lot bigger. You get to block your vision with a piece of plastic embedded in your eye in exchange for a barely noticible piece of jewelery.
Meh, it’d be ok for me since my right eye isn’t exactly normal, I’ve got no feeling in it and I have no sight in that eye. So hey, I may as well make some use of it.
Once I even put a completely black contact lens in it, now THAT got me some looks.
You’re a pirate 
Dude, I can only dream.
It wouldn’t block your vision. Last I checked, you see out of that small hole in the center of the eye, not the white part.
It still looks annoying.
Couldn’t have said it any better Loki.
