For cosmetic purpose, the original eye replaced with a false eye. This eye is made up of medical grade plastic acrylic however some glass eyes are made with cryolite glass. A glass eye or ocular prosthesis does not improve or restore vision. The only purpose of glass eye is to restore the confidence of a person who loses their eye because of any disease or traumatic damage.
