Understand the structure of the fibrous layer of the eye, which consists mainly of two parts: the cornea and the sclera.
Recall that the cornea is the transparent, clear part of the fibrous layer that allows light to enter the eye.
Recognize that the sclera is the white, opaque portion of the fibrous layer, providing protection and structural support to the eye.
Eliminate options that are not part of the fibrous layer: the choroid is part of the vascular layer, and the retina is the innermost neural layer.
Conclude that the white and opaque portion of the fibrous layer is the sclera.

Sclera

The sclera is the white, opaque portion of the fibrous layer. It covers most of the eyeball and maintains the shape of the eye while protecting internal components. Its opacity distinguishes it from the transparent cornea.

Fibrous Layer

Cornea

The cornea is the transparent, dome-shaped front part of the fibrous layer that allows light to enter the eye. Unlike the sclera, it is clear and plays a key role in focusing vision. Recognizing its transparency helps differentiate it from the sclera.
