What is the White Part of the Eye Called?

The white of the eye is known as the sclera and plays an essential role in protecting and maintaining the structure of the eye. The sclera makes up about 80% of the outermost layer of the eye and provides much of the strength and stability of the eye. This part of the eye is also known as the “white of the eye” and is often referred to as the “eyeball”.

The Function of the Sclera

The sclera has a variety of functions that are important to the overall health of the eye. The main function of the sclera is to provide protection and structure to the eye. It acts as a barrier between the environment and the delicate inner structures of the eye. Additionally, it provides the eye with strength, stability and flexibility, allowing it to expand and contract in response to changes in the environment. Finally, the sclera helps to keep the shape of the eye and focuses the light that enters it.

How the Sclera is Formed

The sclera is formed by a layer of collagen and elastic fibers. Collagen is the main structural protein in the body and is responsible for the flexibility and strength of the sclera. Elastic fibers are also found within the sclera and are important for the flexibility and elasticity of the eye. These fibers allow the eye to move in response to changes in the environment.

The sclera serves a number of important roles in maintaining the health of the eye and vision. It is important to regularly check the health of the sclera to ensure that it is functioning properly and that it is providing adequate protection and stability to the eye. Regular eye exams can help to identify any issues that may arise with the sclera early on, thus helping to ensure the long-term health of the eye and vision.
