An ocular prosthesis, artificial eye or glass eye is a type of craniofacial prosthesis that replaces an absent natural eye following an enucleation, evisceration, or orbital exenteration. Someone with an ocular prosthesis is altogether blind on the affected side and has monocular (one sided) vision.

The prosthesis fits over an orbital implant and under the eyelids. The ocular prosthesis roughly takes the shape of a convex shell and is made of medical grade plastic acrylic. A few ocular prostheses today are made of cryolite glass. A variant of the ocular prosthesis is a very thin hard shell known as a scleral shell which can be worn over a damaged or eviscerated eye. Makers of ocular prosthetics are known as ocularists.

Visual prosthesis are currerntly in research which could provide vision to the artificial eye.
