The conjunctiva is a loose connective tissue that covers the surface of the eyeball (bulbar conjunctiva) and reflects back upon itself to form the inner layer of the eyelid (palpebral conjunctiva). This tissue firmly adheres to the sclera at the limbus, where it meets the cornea. The accessory lacrimal glands (Krause and Wolfring), along with goblet cells, are contained within the conjunctiva and are responsible for keeping the eye lubricated.
