Which of the following structures is involved in protecting the eye?

• A. Ciliary body
• B. Cornea
• C. Sclera
• D. Iris

Answer: (C)

The sclera is involved in protecting the eye due to its tough, fibrous structure. It forms the outer layer of the eyeball and provides a protective casing that helps maintain the shape of the eye while also serving as an attachment point for the eye muscles. This rigidity is important for safeguarding the more delicate internal structures of the eye, such as the retina and lens, from external trauma. In contrast, while the cornea plays a critical role in focusing light and is the primary barrier against foreign materials, it is more transparent and not as robust as the sclera. The ciliary body is mainly involved in the accommodation process for focusing and producing aqueous humor, while the iris regulates the amount of light entering the eye through the pupil. While all these structures play essential roles in the eye's function and overall health, it is the sclera's strength and protective nature that makes it a key structure in safeguarding the eye against injury.
