1.Cornea: The journey of sight begins at the cornea, a transparent dome-shaped layer covering the front of the eye. It acts as a protective barrier and helps to focus light onto the retina.

2.Iris: Behind the cornea lies the colorful iris, which regulates the amount of light entering the eye by adjusting the size of the pupil. The iris gives our eyes their distinctive hue.

3.Pupil: The black center of the eye, the pupil, is essentially a hole through which light passes. It dilates in dim light to allow more light in and constricts in bright light to reduce the amount of light entering the eye.

4.Lens: Behind the iris and pupil sits the crystalline lens, which fine-tunes the focus of light onto the retina. It changes shape to allow us to see objects at various distances, a process known as accommodation.

5.Retina: The retina lines the inner back surface of the eye and contains millions of photoreceptor cells called rods and cones. These cells convert light into electrical signals, which are then transmitted to the brain via the optic nerve.

6.Optic Nerve: The optic nerve carries visual information from the retina to the brain, where it is processed and interpreted. It’s essentially the highway that connects the eye to the brain’s visual centers.

7.Vitreous Humor: Filling the space between the lens and the retina is the vitreous humor, a clear gel-like substance that helps maintain the eye’s shape and provides support to the retina.

8.Sclera: The tough, white outer layer of the eye is called the sclera. It provides structural support and protects the delicate inner components of the eye.

9.Choroid: Situated between the sclera and the retina, the choroid is a layer rich in blood vessels that supply oxygen and nutrients to the retina.

10.Ciliary Body: This structure produces the aqueous humor, a fluid that nourishes the lens and maintains the eye’s pressure.
