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.
The sclera is the âwhiteâ of the eye. It is a relatively thick and opaque layer, consisting of two finer layers of tissue â conjunctiva and episclera. In these two layers there are visible blood vessels. The thickness of the sclera varies and has its strongest structure in the posterior part of the eye.
