The sclera, the white outer layer of the eyeball, has two primary functions: it maintains the eye's shape and protects it from injury. Muscles attached to the sclera also facilitate eye movement.
Functions of the Sclera
The sclera serves several vital roles in maintaining eye health and function:
-
Structural Support: The sclera acts as a tough, fibrous outer layer that supports the eyeball, preventing it from collapsing. As stated in the reference, it "maintains your eye's shape."
-
Protection: It shields the delicate inner structures of the eye from external injury and damage. According to the reference, it "protects it from injuries."
-
Muscle Attachment: Eye muscles attach to the sclera, allowing for coordinated eye movements. These muscles work together to enable you to look in different directions.
Summary Table
| Function | Description |
|---|---|
| Structural Support | Maintains the shape of the eyeball. |
| Protection | Shields the inner eye from injury. |
| Muscle Attachment | Provides attachment points for muscles that control eye movement. |
In essence, the sclera is crucial for both protecting the eye and enabling its functionality.
