Causes

• Pinkeye. When the white of the eye becomes pink or red, it’s called pinkeye. Conjunctivitis is another name for pinkeye.  The conjunctiva is the membrane that covers the white of the eye.  It becomes pink when it is infected or irritated. Pinkeye (conjunctivitis) has many causes.
• Viral conjunctivitis is the main cause of pink eyes without pus. Most often, it is part of a cold.
• Bacterial conjunctivitis. Pinkeye plus the eyelids are stuck together with pus.  Most likely, this is a secondary infection of a viral conjunctivitis. 
• Allergic conjunctivitis from pollens. Most children with eye allergies also have nasal allergies (hay fever). Symptoms include sneezing and clear nasal discharge.
• Irritant conjunctivitis from sunscreen, soap, chlorine in pool water, smoke, or smog. Irritants can also be transferred by touching the eye with dirty fingers. Irritants can be food or plant resins.
• Foreign body (FB). If only one side has pinkeye, a FB in the eye must be considered.
• Serious Cause. A bacterial infection of the eyelids and skin around them. Causes the lids to be very red and swollen.

Return to School

• Pinkeye with a watery discharge is harmless. There is a slight risk it could be passed to others. Children with pinkeye from a cold do not need to miss any school.

1. What You Should Know:
   • Some viruses cause watery eyes (viral conjunctivitis).
   • It may be the first symptom of a cold.
   • It isn't serious. You can treat this at home.
   • Colds can cause a small amount of mucus in the corner of the eye.
   • Here is some care advice that should help.
2. Eye Cleansing:
   • Cleanse eyelids with warm water and a clean cotton ball.
   • Try to do this every 2 hours while your child is awake and at home.
   • This usually will keep a bacterial infection from occurring.
3. Artificial Tears:
   • Artificial tears often make red eyes feel better. No prescription is needed.
   • Use 1 drop per eye 3 times a day as needed. Use them after cleansing the eyelids.
   • Antibiotic and vasoconstrictor eyedrops do not help viral eye infections.
4. Eye Drops: How to Give
   • For a cooperative child, gently pull down on the lower lid. Put 1 drop inside the lower lid. Then ask your child to close the eye for 2 minutes. Reason: So the medicine will get into the tissues.
   • For a child who won't open his eye, have him lie down. Put 1 drop over the inner corner of the eye. If your child opens the eye or blinks, the eye drop will flow in. If he doesn't open the eye, the drop will slowly seep into the eye.
5. Contact Lenses:
   • Children who wear contact lenses need to switch to glasses for a while.
   • Reason: To prevent damage to the cornea.
6. Return To School:
   • Pinkeye with watery discharge is harmless. There is a slight risk it could be passed to others.
   • Children with pink eyes from a cold do not need to miss any school.
   • Pinkeye is not a public health risk. Keeping these children home is over-reacting. If asked, tell the school your child is on eye drops (artificial tears).

   • Pinkeye with a cold usually lasts about 7 days.
