Sclera and conjunctiva


The sclera, also known as the “white of the eye”, is the outermost layer of the eye. It is a thick and fibrous layer consisting predominantly of a type of protein called collagen. Its strength helps maintain the shape of the eyeball and protects the internal structures from trauma. The sclera is covered by a thin transparent membrane called the conjunctiva. It keeps the surface of the eye moist and offers further protection to the eye.
