The cornea serves as a protective covering for the front of the eye and also helps focus light on the retina at the back of the eye. After passing through the cornea, light travels through the pupil (the black dot in the middle of the eye).

Apr 22, 2018 · The fibrous layer is the outermost layer and consists of the cornea and sclera, which are continuous with one another. The cornea is located in the centre of the anterior aspect of the eye and is transparent. The sclera, which covers the rest of the eye, is white.
The cornea is a dome shape covering the front of the eye. Although it is very transparent and only half a millimetre thick, the cornea helps protect the eye from external damage. Together, the cornea and the lens bend light that comes into the eye, which is one stage of the process of giving us vision.

- Eyelid anatomy. The eyelids are soft tissue structures that cover and protect the anterior surface of the eyeball. The anatomy of the eyelid may seem complex, but if we dissolve its multi-layered structure it is actually quite simple
- Lacrimal gland. The lacrimal gland is a part of the lacrimal apparatus, which besides the gland consists of its numerous ducts, the lacrimal canaliculi, lacrimal sac and nasolacrimal duct.
- Eye muscles. There are two groups of eye muscles: Extraocular muscles that move the eyeballs within the orbit. Intrinsic ocular muscles which are within the eyeball itself and control how the eyes accommodate.
The cornea is the clear outer layer of the eye that protects the eye from harmful particles and ultraviolet rays. This part of the eye is also responsible for bending the light that enters the eye. The cornea’s shape or curvature determines the eye’s focusing abilities for both near and distant objects.
Nov 4, 2023 · The innermost layer of the cornea is called the endothelium which rests on Descemet's Membrane. The endothelium removes water from cornea, helping to keep the cornea clear. The middle layer of the cornea, between the two membranes is called the stroma and makes up 90% of the thickness of the cornea.
