Making an Artificial Eye


Take an impression of the eye socket. Impression is encased in dental stone, which is very similar to plaster of paris. We obtain a wax piece that constitutes a pattern for the artificial eye. An iris button, similar to the pupil, iris, and cornea of the front of the eye is chosen and built into the wax pattern.

When satisfied with the wax pattern, we make a final mold of dental stone around it in a fiberglass flask. A thin layer of plastic is ground, filed and sanded from the front surface of the eye.


We then make a painting shell by placing a clear polyethylene. The coloring of the artificial eye is done with the greatest of care. When the color is judged to be correct, the eye is returned to the final mold and the layer of transparent acrylic is cured onto the front surface to protect the color.

HISTORY

 The very first artificial eyes were made by Roman and Egyptian priests as early as the 5th century BC. They were made of painted clay attached to cloth and worn outside the socket. .

 Centuries later, the first in-socket artificial eyes were made of gold, coated with coloured enamel. Then, in the later part of the sixteenth century, the Venetians started making artificial eyes out of glass.

RAW MATERIALS

 Plastic and glass are the main material that makes up the artificial eye. Wax and plaster of paris are used to make the molds. A white powder called alginate is used in the molding process. Paints and other decorating materials are used to add life-like features to the prosthesis.
