The first evidence of human’s wearing an artificial eye was recently uncovered in the southeastern part of Iran. The woman, carbon-dated back to 2900 BCE, was discovered wearing a rudimentary ocular prosthesis worn outside of the eye socket. This crude, hemispherical form was made of clay and covered with a thin layer of gold. Tiny holes were also drilled into both sides of the eye, through which gold thread passed to hold the eyeball in place.
