The eyes are susceptible to infection because they are not sterile. They rely on lysozyme (an enzyme found in the tears) to destroy bacteria.
Bacteria line the surface of the eyelids (all the way down into the shaft of the eyelashes), which makes the conjunctiva predisposed to germs and thus results in conjunctivitis.
Conjunctivitis can be classified as infectious or noninfectious.
Infectious conjunctivitis is caused bye viruses like staphylococci, pneumococci, streptococci or chlamydia trachomatis
Noninfectious conjunctivitis on the other hand is caused by allergies, chemicals, air pollutants, smoke and household cleaners, or underlying diseases.
Additionally, conjunctivitis can be caused by hemorrhaging from trauma or changes in pressure within the head. Also, an incomplete opened tear duct or herpetic conditions (such as herpes simplex or herpes zoster) also can causes conjunctivitis.
Symptoms of Conjunctivitis
The symptoms of infectious conjunctivitis caused by a bacteria or viruses are:
• Eye pain
• Swelling of the eyes
• Redness in the eyes
• Yellow, green or watery discharge from the eyes which collects overnight and crusts over the eye

The symptoms of conjunctivitis caused by allergies are:
• Intense itching of the eye
