Multiple Choice

Which of the following is NOT a function of the sclera?

Protects the inner components of the eye

Serves as an attachment point for extraocular muscles

Provides structural support to the eyeball

Facilitates the refraction of light

Verified step by step guidance

Understand the role of the sclera in the anatomy of the eye. The sclera is the white outer layer of the eyeball that provides protection and structural support.

Identify the functions of the sclera: it protects the inner components of the eye, serves as an attachment point for extraocular muscles, and provides structural support to the eyeball.

Recognize that the sclera does not play a role in the refraction of light. Refraction is primarily facilitated by the cornea and the lens, which are transparent structures that bend light to focus it on the retina.

Compare the given options with the known functions of the sclera. The option that does not align with the functions of the sclera is the one that involves refraction of light.

Conclude that the correct answer is the option stating that the sclera facilitates the refraction of light, as this is not a function of the sclera.
