Structure of the Eye
The human eye is a complex organ with various components working together to facilitate vision. These structures work together to enable the perception of visual stimuli.
- Cornea: Transparent outer layer that helps focus light.
- Sclera: Tough, white outer layer providing structural support.
- Iris: Colored part controlling the size of the pupil and light entering.
- Pupil: Black opening allowing light into the eye.
- Lens: Transparent structure focusing light onto the retina.
- Retina: Innermost layer with light-sensitive cells (rods and cones) converting light into signals.
- Macula: Central area responsible for detailed vision.
- Optic Nerve: Transmits visual signals from the retina to the brain.
- Vitreous Humor: Gel-like substance maintaining eye shape.
- Aqueous Humor: Clear fluid nourishing the front part of the eye.
- Ciliary Body: Contains muscles controlling lens shape for focusing.
- Choroid: Supplies blood to the retina.
- Conjunctiva: Thin layer covering the white part of the eye and inner eyelids.

Diagram of Eye
The diagram of eye includes both the external and internal structure of an eye. Externally, the cornea and iris regulate light, while the lens internally focuses it on the retina. Photoreceptor cells in the retina convert light to neural signals. The optic nerve transmits these signals to the brain for visual interpretation. Additional structures like the sclera, vitreous humor, and ciliary muscles contribute to the eye functions. In this article, we will study the external and internal structure of an eye along with its functions in detail.
