This is the white part of the eye.  The sclera is the firm wall of the eye that gives the eye its shape and structure.  Made of collagen fiber, the sclera is relatively tough. It is also continuous with the clear cornea in the front of the eye.  The sclera is covered by a thin layer of skin called the conjunctiva. This clear skin covers the eyeball and contains small blood vessels you can see in the mirror.  When you are looking at the “white” of your eye, you are looking through this conjunctival skin at the scleral wall of the eye itself.
