The conjunctiva is a tissue that lines the inside of the eyelids and covers the sclera. It is composed of unkeratinized, stratified squamous epithelium with goblet cells, and stratified columnar epithelium. The conjunctiva is basically transparent, and the white colour we see is actually sclera.

The anterior segment or anterior cavity [1] is the front third of the eye that includes the structures in front of the vitreous humour: the cornea, iris, ciliary body, and lens. [2] [3]
In the anatomy of the eye, the conjunctiva (pl.: conjunctivae) is a thin mucous membrane that lines the inside of the eyelids and covers the sclera (the white of the eye). [1] It is composed of non-keratinized, stratified squamous epithelium with goblet cells , stratified columnar epithelium and stratified cuboidal epithelium (depending on the ...

The globe of the eye, or bulbus oculi, is the frontmost sensory organ of the human ocular system, going from the cornea at the front, to the anterior part of the optic nerve at the back. More simply, the eyeball itself, as well as the ganglion cells in the retina that eventually transmit visual signals through the optic nerve. [ 1 ]
Together, the cornea and lens refract light into a small image and shine it on the retina. The retina transduces this image into electrical pulses using rods and cones. The optic nerve then carries these pulses through the optic canal. Upon reaching the optic chiasm the nerve fibers decussate (left becomes right). The fibers then branch and ...
The conjunctiva covers the sclera, or whites of the eyes, as well as the insides of the eyelids and provides nutrients to underlying and surrounding tissue. The conjunctiva is also one of the closest vascularized tissues to the cornea. As such, it provides a major source of immune components in the cornea.
In the leftmost photo, the pupil is relatively posterior (set back), indicating an EZ ratio of < 0.5 and an anterior chamber deeper than 2.5 mm. In the middle photo, the pupil is midway between the sclera posteriorly and the cornea anteriorly, indicating an EZ ratio of 0.5, and a medium chamber depth of about 2.5 mm.
