The sclera plays an important protective role for various structures of the eye, including the cornea. It is the tough, white outer layer of the eyeball, providing both shape and protection to the eye's internal components. The sclera surrounds and supports the eye, ensuring that the more delicate structures within, like the cornea, are shielded from potential injury or harm. By providing this support, the sclera helps maintain the integrity of the eye and aids in its overall function.

While the sclera is closely associated with the eye as a whole, its primary function regarding protection is most directly related to the cornea, which faces the external environment and is more susceptible to damage. It is worth noting that the retina, iris, and lens serve different functions within the eye, and their protection involves other mechanisms or structures rather than direct protection from the sclera.
