Oldest Artificial Eye (4,800 years old)

According to a 2006 report, Iranian archaeologists in "Burnt City" announced the unprecedented discovery of an artificial eyeball, dated to 4,800 years ago, in this historic site. The eyeball belonged to a sturdy woman who was between 25 to 30 years of age at the time of death, and its material consisted of natural tar mixed with animal fat. Studies on the eyeball also suggest the formation of an abscess in the eyelid due to long-term contact with the eyeball. Moreover, remaining eyelid tissues are still evident on this artificial eyeball.
