The eye has three layers. These layers are arranged concentrically, meaning they are like rings, one inside the other.
Layers of the Eye
Here is a breakdown of the three layers:
| Layer | Description | Components |
|---|---|---|
| Exterior | The outermost layer. It provides protection and structure to the eye. | Sclera: The white part of the eye. Cornea: The clear front surface of the eye. |
| Uvea | The middle layer. It is a vascular layer, meaning it is rich in blood vessels. | Iris: The colored part of the eye. Ciliary body: Involved in focusing. Choroid: Supplies blood to the retina. |
| Retina | The innermost layer. It is made of nervous tissue and is responsible for detecting light and color. | Contains the cells that sense light and transmit images to the brain. |
Key Takeaways:
- The layers are not just for structural support but serve important visual functions.
- Each layer plays a crucial role in ensuring the eye functions properly.
- The three-layered structure is fundamental to understanding how vision works.
