How long have artificial eyes been around?
Artificial eye-making has been practiced since ancient times. The first ocular prostheses were made by Roman and Egyptian priests as early as the fifth century B.C. In those days, artificial eyes were made of painted clay attached to cloth and worn outside the socket. It took many centuries for the first in-socket artificial eyes to be developed. At first, these were made of gold with colored enamel. Then, in the later part of the sixteenth century, the Venetians started making artificial eyes out of glass. These early glass eyes were crude, uncomfortable to wear, and very fragile. Even so, the Venetians continued making them and kept their methods secret until the end of the eighteenth century. After that, the center for artificial eye-making shifted to Paris for a time; but by the mid-nineteenth century, German glass-blowers had developed superior techniques, and the center for glass eye-making moved to Germany. Shortly thereafter, glass eye-making was introduced in the United States
