Eye - Red Without Pus  
Back to Index

Does this describe your child's symptoms?

  • Redness or pinkness of the white of the eye and inner eyelids
  • May have increased tearing (watery eye)
  •  Eyelid may be puffy or mildly swollen
  • No pus or other discharge


  • Pinkeye: When the white of the eye (sclera) 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 (part of a cold) is the main cause of pink eyes without pus.
  • Bacterial conjunctivitis: pink eye plus the eyelids are stuck together with pus.  Usually, this is a secondary infection of a viral conjunctivitis. 
  • Allergic conjunctivitis from pollens. Most children with eye allergies also have nasal allergies (hay fever) with sneezing and clear nasal discharge.
  • Irritant conjunctivitis from sunscreen, soap, chlorinated pool water, smoke, or smog, etc.
  • Irritants can also be transferred by touching the eye with dirty fingers (e.g., food or plant resins)
  • Foreign body (FB): If only one side has pinkeye, a FB in the eye must be considered.

Return to School

  • Pink eye with a watery discharge is harmless and mildly contagious. Children with colds in the eye usually do not need to miss any child care or school.

Treatment For Viral Eye Infections
  1. Reassurance:
    • Some viruses cause watery eyes (viral conjunctivitis).
    • It may be the first symptom of a cold.
    • It isn't serious and you can treat that at home.
    • Colds can also cause a small amount of mucus to collect in the inner corner of the eye.
  2. Eye Cleansing: Cleanse eyelids with warm water and a clean cotton ball at least 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 needed)
    • Use 1 drop per eye 3 times a day. Use them after cleansing the eyelids.
    • Antibiotic and vasoconstrictor eyedrops do not help viral eye infections.
  4. Contacts: Children with contact lenses need to switch to glasses temporarily (reason: to prevent damage to the cornea).
  5. Contagiousness:
    • Pink eye with a watery discharge is harmless and mildly contagious.
    • Children with colds in the eye do not need to miss any child care or school.
    • Pinkeye is not a public health risk and keeping these children home is over-reacting. If asked, tell the school your child is on eyedrops (artificial tears).
  6. Expected Course: Pink eye with a cold usually lasts about 7 days.
  7. Call Your Doctor If:
    • Yellow or green discharge develops
    • Redness lasts for more than 1 week
    • Your child becomes worse
Treatment For Mild Eye Irritants
  1. Reassurance: Most eye irritants cause transient redness of the eyes. You can treat that at home.
  2. Face Cleansing: Wash the face with mild soap and water. Wash off eyelids with water. This will remove any irritants.
  3. Eye Irrigation: Irrigate the eye with warm water for 5 minutes.
  4. Eye Drops:
    • Red eyes from irritants usually feel much better after the irritant has been washed out.
    • If they remain uncomfortable and bloodshot, instill artificial tears or a long-acting vasoconstrictor eye drops (no prescription needed).
    • You can ask your pharmacist to recommend a brand.
    • Use 1 drop every 8 to 12 hours as necessary. 
  5. Expected Course: After removal of the irritant, the eyes usually return to normal color in 1 to 2 hours.
  6. Prevention: Try to avoid future exposure to the irritant.
  7. Call Your Doctor If:
    • Develops yellow or green pus in the eye
    • Redness lasts over 7 days
    • Your child becomes worse

And remember, contact your doctor if your child develops any of the "Call Your Doctor" symptoms.
