A prosthetic eye can help improve the appearance of people who have lost an eye to injury or disease. It's commonly called a "glass eye" or "fake eye."
The prosthetic eye includes:

Computer Vision Syndrome
Staring at a computer monitor for hours on end has become a part of the modern workday. And inevitably, all of that staring can put a real strain on your eyes.
The name for eye problems caused by computer use is computer vision syndrome (CVS). CVS is not one specific eye problem. Instead, the term encompasses a whole range of eyestrain and pain experienced by computer users.
Research shows computer eye problems are common. Somewhere between 50% and 90% of people who work at a computer screen have...

Implanting a prosthetic eye (ocular prosthesis) is almost always recommended after an eye is surgically removed due to damage or disease.
Some of the reasons why an eye may be removed are:
infection inside the eye
Types of Surgery
There are two surgical methods for removing a damaged eye. The type of surgery you have will affect the selection of a prosthetic eye. The two methods are:
Evisceration. In this method, the jelly-like inside of the eye is suctioned out. This is done through an incision in the front of the eye. But the procedure preserves tissues in the:
eye socket (orbit)
Enucleation. In this method, the entire eye (the globe-like "eyeball") is cut away and removed from the eye socket.
Your doctor will decide which method to use based on:
type of eye condition you have
degree of damage to the eye
Why Is a Prosthetic Eye Used?
A prosthetic eye can improve the appearance of the affected eye socket. For most people it is vastly preferable to wearing an eye patch or bandage.
If the entire eye is removed, an ocular implant and prosthesis prevent the tissues in the eye socket from growing to fill the empty space.
A prosthetic eye cannot restore
vision. After removal of the natural eye and placement of a prosthetic eye, a person will have no vision in that eye.
What Is a Prosthetic Eye Made of?
At one time a "glass eye" was really made of glass. Today, a prosthetic eye is generally made of hard, plastic acrylic. The prosthetic eye is shaped like a shell.
The prosthetic eye fits over an ocular implant. The ocular implant is a separate hard, rounded device that is surgically and permanently embedded deeper in the eye socket.
An ocular implant is often wrapped with living tissue or a synthetic cushioning material before placement.
