    • According to the website artificialeye.com, medical-quality PMMA acrylic is currently used for prosthetic eyes. PMMA stands for polymethyl-methacrylate, and according to Boedeker Plastics, PMMA is "is optically transparent, unaffected by moisture, and offers a high strength-to-weight ratio." Custom Ocular Prosthetics notes allergies to PMMA are highly unlikely because the material is very bio-compatible after being surgically inserted.

    Glass Eyes

    • Glass was commonly used for prosthetic eyes until World War II. According to the website artificialeyeclinic.com, the eyes were made by German glass blowers. The American military developed plastic prosthetic eyes during the war.

    Partial Prosthetic Eyes

    • In cases where the eye ball is damaged and does not function, a scleral shell may be used. The shell is painted or finished to match the good eye and worn over the damaged eye ball to give a more normal appearance.
