The conjunctiva is a thin membrane that serves as a protective barrier between the eyelids and the eyeball; it is maintained moist and clear of infection through the lacrimal apparatus, which produces tears to constantly irrigate the conjunctiva and drain the tears into the nasolacrimal sac (Jarvis, 280). The conjunctiva can be examined in the clinical setting by having the clinician pull down on the lower lids as the patient focuses his or her vision upward.
