The sclera is the tough, white outer layer of the eye that helps maintain the shape of the eyeball and protects its internal parts. It is made of tough, fibrous tissue and serves as the attachment point for the muscles that move the eye. In GCSE Biology, the sclera is studied as part of the eye’s structure, including its role in protecting and supporting vision.
