Definition & Meaning of "sclera"

What is "sclera"?

The sclera, often referred to as the "white of the eye," is the tough, protective outer layer that covers most of the eyeball. It is composed of dense connective tissue and helps maintain the shape and integrity of the eye. The sclera provides attachment points for the muscles that control eye movement and serves as a barrier to protect the delicate structures inside the eye. It also plays a role in maintaining eye pressure and providing structural support. While it is primarily white, the sclera may have a slightly bluish tint in some individuals. Overall, the sclera serves as a vital component of the eye, contributing to its overall function and protection.
