Which of the following describes an artificial eye used for cosmetic purposes?

The term "artificial eye" refers specifically to a device designed to replace a missing eye for cosmetic reasons. This type of artificial eye is created to match the appearance of a natural eye, helping to restore a person's facial symmetry and confidence following the loss of an eye. These prosthetic devices are usually crafted from materials that mimic the look of a natural iris and sclera, thereby providing a realistic cosmetic outcome.

While other terms like "intraocular lens," "prosthetic eye," and "corneal implant" refer to different types of ocular devices, they do not specifically denote an artificial eye meant solely for cosmetic purposes. An intraocular lens, for example, is used to replace the natural lens of the eye usually after cataract surgery and serves a functional purpose in vision. A prosthetic eye may sound similar, but it typically refers to more than just cosmetic function—it can also involve some aspect of restoration for eye function. Lastly, a corneal implant is a medical device used to replace or restore the cornea, which is important for visual clarity rather than cosmetic appeal. Therefore, "artificial eye" is the most accurate term that describes a device specifically for cosmetic enhancement in cases of eye loss.
