What is the sclera?

The sclera is the tough, protective outer layer of the eyeball that gives the eye its shape, and it appears as the white part of the eye. It surrounds most of the eyeball and provides attachment points for the muscles that move the eye. It is opaque and white, unlike the clear, front surface that covers the eye—the cornea. The eye socket, or orbital cavity, is the bony structure that houses the eye within the skull. So, identifying the sclera as the white part of the eye best reflects its appearance and role.
