What is described as the "white" part of the eye, providing protection along with the cornea?

The sclera is described as the "white" part of the eye, playing a vital role in providing structural support and protection. It is a tough, fibrous tissue that encases the eye, helping to maintain its shape while offering a protective barrier against injury. The sclera works in conjunction with the cornea, which is the clear front part of the eye that also aids in protection as well as focuses light onto the retina. Together, these structures form the outer coat of the eye, with the sclera serving as the major protective layer while the cornea is involved in refracting light and sensory processing. Understanding the anatomy and functions of these eye parts is crucial in optometry, as they collectively contribute to vision and overall eye health.
