Tattoo artist Rodrigo Fernando dos Santos, 39, of Sao Paulo, decided to go ahead with the bizarre procedure after having already had 70 per cent of his body covered in ink.
The work involved a special syringe being used to inject the ink into the whites of his eyes.
The irreversible procedure involved using a syringe to inject ink into the sclera - the protective outer layer - of his eyes, 9News reports.
The ink used to inject his eye is believed to be the same used for tattoos on the rest of the body.
Eye specialists have advised against the procedure which some warn can cause inflammation and possibly even vision loss, according to 9News.
