The conjunctiva keeps the eye moist and protects the delicate structures of the eye. There are three sections of the conjunctiva:
- The Palpebral Conjunctiva: The lining of the eyelids
- The Fornix Conjunctiva: The area where the eyelid meets the eyeball
- The Bulbar Conjunctiva: Covering the eyeball
The conjunctiva is very vascular, meaning it has a large number of blood vessels, when the eye is irritated or injured these vessels make the eye appear red. Inflammation of the conjunctiva, or conjunctivitis, is more commonly known as "pink eye."
