The sclera is a part of the human eye. It is the white, fibrous part that can be seen surrounding the iris. Its main purpose is to hold the shape of the eye and protect the fragile structures within it.

The sclera is a tough fibrous white opaque membrane that maintains the size and form of the eyeball and is attached to muscles that move the eye. It is pierced by the optic nerve and, with the transparent cornea, makes up the outermost of three layers covering the eyeball. Tendons attach to the sclera as parallel fibers that then spread out in a fan-shaped manner and allow eye movement in various directions.
