Tattoos are more popular than ever it seems, especially since technology has made them less permanent than they used to be. Whether it's from a struggle to differentiate themselves from the crowd, a new crazy way of artistic expression, or simply because they ran out of space, some people have started getting tattoos on their eyeballs. And we're not talking about permanent makeup or anything else on the outside of the eye -- we're talking ink injected right into the cornea.

Corneal tattooing is dangerous for a number of reasons, because in addition to the usual tattoo risks the cornea version can include infection, perforation, hemorrhage, scarring, and blindness. It started as a means of repairing eye damage and covering scarring, but it's becoming a more and more popular cosmetic procedure.

So would you let a tattoo artist stick a needle in your eye? Talk about regret!
