The sclera (from the Greek skleros, meaning hard), also known as the white of the eye, is the opaque, fibrous, protective, outer layer of the eye containing collagen and elastic fiber.n the development of the embryo, the sclera is derived from the neural crest. In children, it is thinner and shows some of the underlying pigment, appearing slightly blue.
1 The conjunctiva is the thin tissue that covers the sclera. 2  It is the outermost protective coating of the eyeball. 3  The small blood vessels within the conjunctiva may break spontaneously or from injury, causing a red area on the sclera, resulting in a subconjunctival hemorrhage.
