The world's first ever eyeball tattoo was done by a Canadian man, Pauly.
The freaky procedure was carried out to turn a body-art enthusiast's eyes blue.
The tattooer injected ink into the eyeball of volunteer Pauly Unstoppable using a needle, until his eye was completely blue.
And it took a total of 40 insertions of the needle to get the job done. The blue substance used was mixed with antibiotic eyewash.
The experiment was carried out for Canadian company ModProm.
Pauly said he had full confidence in the team working on him, but urged people not to try it at home.
"The procedure was extensively researched and done by people who were aware of the risks and possible complications and that it should not be casually attempted," The Sun quoted Pauly, as saying.
"Now that this experiment has been started, please wait for us to either heal or go blind before trying it," he added.
