Maybe it's a sign of the times, or, I'm just catching up with how fast and seemingly uncontrollably the world is evolving. Just recently read an article published in The New York Times by one Dr. Rock Positano called Don't Turn Blind, where he attempts to discourage the idea of a relatively new body piercing ...eye tattoo.
Although Doctors of Ophthalmology have and isn't totally against using tattoos in the area of the eye where cases of sustained scarring from trauma/bruising and burning have occurred, these professionals do not recommend eye tattoos that seem to have become a sort of phenomena in the body piercing industries.
Dr. Positano writes of 2 procedures that one such body piercing industry used initially to tattoo the eyeballs of people who wanted to turn the whites of their eyes, blue. .. the traditional needle method where the ink on the needle failed to hold. The second, a syringe method which injected ink into the eye worked, leaving one man to say it only felt like something was in his eye...well duh!
The dangers of eye tats:
Infection
Perforated eye
Hemorrhage
As I've stated, Doctors of Ophthalmology find cases where eye tattoos does some good for the patient, but, tats for adornment sake is not advised...
