The sclera is the opaque (usually white), fibrous, protective layer of the eye containing collagen and elastic fibers.[1] In children, it is thinner and shows some of the underlying pigment, appearing slightly blue. In the old, however, fatty deposits on the sclera can make it appear slightly yellow.
