Allergic conjunctivitis and conjunctivitis caused by an infection can be hard to distinguish. Both have
similar symptoms, such as redness, itching and swelling in the eye area. However, when conjunctivitis
is caused by allergies, both eyes are usually affected. Viral or bacterial conjunctivitis can affect either a
single eye or both eyes. It is important to pinpoint whether someone has conjunctivitis because of
allergies or infection since each condition has a different treatment.

Discharge from the eyes may accompany the other symptoms. In bacterial conjunctivitis, the
discharge will be somewhat thick and colored white, yellow, or green. Sometimes the discharge will
cause the eyelids to stick together when the child awakens in the morning. In viral or allergic
conjunctivitis, the discharge may be thinner and may be clear.

All types of infectious conjunctivitis are contagious and can spread from one eye to the other by
touching the eyes. A child can first become infected from direct contact with someone who has the
infection or something that person has touched, such as a used tissue. The infectious organisms can
also spread through coughing and sneezing. In addition, certain viruses spread in the summertime
when children swim in contaminated water or share contaminated towels.

Prevention

To prevent infectious conjunctivitis, your child should wash his or her hands often with warm water
and soap. Children also should not share eye drops, tissues, eye makeup, washcloths, towels or
pillowcases with others.

If your child already has conjunctivitis, he or she should wash their hands after touching the eyes.
Your child also should not touch the infected eye and then touch the other eye without first washing
his or her hands. Be sure to wash your own hands thoroughly after touching your child's eyes, and
throw away items like gauze or cotton balls after they have been used. Wash towels and other linens
that your child has used in hot water separately from the rest of the family's laundry to avoid
contamination.

If you know your child is prone to allergic conjunctivitis you should keep windows and doors closed
on days when the pollen is heavy, and dust and vacuum frequently to limit allergy triggers in the
home.

Usually conjunctivitis is a minor eye infection, but it has the possibility to develop into a more serious
condition. See your eye care practitioner for a diagnosis before using any eye drops in your medicine
cabinet from previous infections or eye conditions.
There are three types of conjunctivitis: allergic, bacterial and viral.
Conjunctivitis is commonly referred to as "pink eye" since the eye is
usually red and swollen.

One of the most common symptoms is discomfort or pain, which may
feel like having sand in the eye. Many children have redness of the eye
and inner eyelid as well. The child may also have swollen eyelids and be
sensitive to bright light. Itchiness and tearing are common with allergic
conjunctivitis.
