Commonly known as pinkeye
Conjunctivitis is the inflammation of the outer most layer of the eye and the inner side of the eyelid. Conjunctivitis infections commonly come in one of three flavours: viral
bacterial
or allergic. There is
however
several other cases of less common conjunctivitis:
- Chemicals
- Thermal and ultraviolet burns
- Foreign bodies
- Overuse of contact lenses
- Toxins
- Vitamin deficiency
- Dry eye
sometimes due to inadequate eyelid closure
- Exposure to chickens infected with Newcastle disease

Lets take a quick look at the three most common types of conjunctivitis.

The first is viral conjunctivitis. This type is transmitted by contact with a variety of contagious viruses. These required viruses need not be any harsher than the common cold virus
as these cases are generally associated with upper respiratrory tract symptoms.

Bacterial conjunctivitis is most commonly caused by the infected's own skin or respiratory flora due to pyogenic bacteria. Another common way to spread infection
generally by females
is through sharing of facial lotions or eye makeup. And lastly
it is possible to share this kind of "pinkeye" through contact with other people and/or their environment.

The last form that we will be looking at is allergetic conjuctivitis. This type generally follows a seasonal pattern
and is more common among those with allergic conditions. Unlike the others
allergetic conjuctivitis tends to take over both eyes
and is accompanied by swollen eyelids. It is caused by reactions to such substances as perfume
drugs
cosmetics
contact lenses
or protein deposits.
