The External Structure of an Eye


Sclera: It is a tough and thick white sheath that protects the inner parts of the eye. We know it as the ‘White of the eye’.

Conjunctiva: It is a thin transparent membrane that is spread across the sclera.

Cornea: It is the transparent layer of skin that is spread over the pupil and the iris.

Iris: It is a pigmented layer of tissues that make up the colored portion of the eye.

Pupil: It is the small opening located at the middle of the Iris. It allows light to come in.


The Internal Structure of an Eye

Lens: It is a transparent, biconvex, and an adjustable part of an eye.

Retina: It is the layer present at the back of the eye where all the images are formed.

Optic nerve: It is located at the end of the eyes, behind the retina.

Aqueous Humour: It is a watery fluid that is present in the area between the lens and the cornea.

Vitreous Humour: it is a semi-solid, transparent, jelly-like substance that covers the interior portion of the eyes.
