The correct answer is

is composed of proteins and cells.

The correct answer is is composed of proteins and cells.

The cornea is the transparent front part of the eye's outer coat, made of epithelial and endothelial cell layers and a stroma of regularly arranged collagen (protein) fibres. This orderly structure and the absence of blood vessels keep it transparent; it is nourished by tears and aqueous humour.

The light-sensitive screen is the retina, the muscular diaphragm is the iris, and the cornea is avascular.

Short trick: Cornea = clear and bloodless — which is why corneal grafts are rarely rejected.
