This evolutionary trait underscores the sclera's role beyond mere protection, positioning it as a key element in social interaction and visual perception. In some species, the sclera is pigmented to reduce glare, while in others, the entire globe is translucent to aid in nocturnal vision.

Similarly, the blue appearance observed in some infants is often due to the translucency of the thin sclera, allowing the underlying choroidal veins to show through. This transitional zone is far more than a simple line; it houses the limbal stem cells essential for the continuous renewal of the corneal epithelium.
The thickness of the tissue varies significantly, being thickest at the posterior pole where the optic nerve exits and gradually thinning towards the anterior region. Clinical Significance and Surgical Considerations Ophthalmologists frequently utilize the sclera as a surgical pathway.

Conditions such as scleritis, an inflammatory disorder, cause severe pain and can lead to thinning or perforation if untreated. The sclera, often referred to as the white of the eye, forms the tough, outermost layer of the eyeball.
