What component of the eye provides shape and protection?

The sclera is the outermost layer of the eyeball, commonly known as the "white part" of the eye. This tough, fibrous tissue plays a crucial role in maintaining the shape of the eye, which is essential for proper focus and image formation. Additionally, the sclera provides protection for the more delicate internal structures of the eye, such as the retina and lens, serving as a shield against physical damage and infections. Because of its robust nature, the sclera supports the eye's structure, allowing it to withstand various pressures and forces that may occur during everyday activities. This unique combination of shape maintenance and protective function underscores the importance of the sclera in the overall health and operation of the visual system.
