2. Sclera

The sclera is the white part of our eyes. It slightly overlaps the top and bottom of the back end of the cornea. Its exterior is smooth and white, but the interior is a brown, grooved surface. It is surprisingly strong and flexible, and this flexibility gives the sclera even more strength. It is made up of collagen and elastic fibers, and its job is to protect the eye, as well as maintain its shape.
