Sclera
What is sclera?
The sclera, also known as the white or white of the eye, is the opaque (usually white, though certain animals, such as horses and lizards, can have black sclera), fibrous, protective, outer layer of the eye comprising collagen and material fiber. The sclera is the white outer wall of the eye. It is a tough, fibrous tissue that extends from the cornea (the clear front section of the eye) to the optic nerve at the back of the eye. The sclera gives the eye its white color.
The sclera is “the whites of your eyes”, the white outer coat of the eyeball that surrounds the cornea all the way back to the optic nerve. The sclera is continuous in the front of the eye with the cornea and in the back of the eye with the external sheath of the optic nerve. The sclera may be damaged by corrosive chemicals or vapors.
Always wear proper eye protection and know the hazards of the materials you are working with. The sclera is continuous in the front of the eye with the cornea and in the back of the eye with the external sheath of the optic nerve.
