Melanin-containing layer of the eye's vascular tunic.

Question

Quizplus · Accepted Answer

The choroid is the layer of the eye's vascular tunic that contains melanin, which helps absorb excess light rays and prevent light scattering within the eye. The sclera (A) is the tough, white outer layer of the eye that forms the white of the eye. The ciliary body (C) is a structure located between the iris and choroid that produces and secretes the aqueous humor. The cornea (D) is the transparent outer layer that covers the front of the eye, and the lens (E) is a transparent structure behind the iris that helps focus light onto the retina.
