There are several synonyms for the term "fake eyes." The most common synonym is "glass eyes," which refers to prosthetic eyes made from glass or plastic used to replace a missing or damaged eye. Another synonym is "ocular prosthesis," which is a medical device that is custom-made to match the size, shape, and color of your natural eye. "Artificial eyes" also refer to the prosthetic eyes that can be crafted from various materials, such as acrylic, porcelain, or silicone, to mimic the appearance of a natural eye. Similarly, the term "false eyes" also describes prosthetic eyes that are not real but serve the same purpose as the natural eye.
