Waking up to a child with red, crusty, watery eyes is every parent’s dread — is it pink eye, how is it treated, and can they go to school? Conjunctivitis in children is extremely common, especially in classrooms and daycares, and most cases are mild and self-limiting. But the right pink eye children treatment depends on the cause, and knowing which type you’re dealing with saves unnecessary antibiotics and missed school days.
This guide covers the three main types of pink eye in children, evidence-based treatment for each, what school policies typically require, and the red flags that mean it’s time to call the doctor.

What Causes Pink Eye in Children
Pink eye (conjunctivitis) is inflammation of the conjunctiva, the clear membrane covering the white of the eye and inner eyelid. In children, three causes dominate. Viral conjunctivitis is the most common — it usually accompanies a cold, starts in one eye and spreads to the other, and produces watery discharge. Bacterial conjunctivitis produces thick, yellow-green discharge that can crust the eyelids shut overnight. Allergic conjunctivitis affects both eyes, causes intense itching and watery eyes, and coincides with sneezing or a runny nose during allergy season.
Telling them apart matters because treatments differ completely. Antibiotics do nothing for viral pink eye, and antihistamines won’t fix a bacterial infection. A clinician can usually distinguish them by symptoms and appearance, sometimes with a quick examination of the discharge. Children with frequent eye irritation should also have their vision checked regularly, since rubbing and discomfort can mask underlying issues.
Viral Pink Eye Treatment
Most childhood pink eye is viral, and like the common cold, it simply needs to run its course — typically 7 to 14 days. There is no specific antiviral treatment for routine viral conjunctivitis, so pink eye children treatment focuses on comfort and preventing spread.
Cool compresses (a clean, damp washcloth) soothe irritation and loosen crusts. Artificial tears — preservative-free formulas are gentlest for children — relieve grittiness and help flush the eye. Encourage your child not to rub their eyes, wash hands frequently, and avoid sharing towels, pillows, or eye drops. Keep them home while symptoms are at their worst, though many school policies allow return once the child feels well enough to participate, since viral pink eye is contagious mainly through direct contact.
Bacterial Pink Eye Treatment
Bacterial conjunctivitis is diagnosed by thick purulent discharge and significant eyelid crusting. Treatment is antibiotic eye drops or ointment prescribed by a clinician — common options include erythromycin ointment, which is often preferred for young children because ointment is easier to administer than drops and less likely to wash out with tears.
With treatment, symptoms usually improve within 24 to 48 hours, and most children are no longer contagious after a full day on antibiotics. Complete the entire prescribed course even if the eyes look better — stopping early risks recurrence. Never use leftover antibiotic drops from a previous episode or another family member; the wrong antibiotic can be ineffective or even harmful. If your child wears contact lenses, they must stop wearing them until the infection fully clears and should discard the current pair or case.
Allergic Pink Eye Relief
Allergic conjunctivitis isn’t contagious at all — it’s an immune response to pollen, dust mites, pet dander, or mold. The hallmark is intense itching in both eyes, often with a clear watery discharge and puffy eyelids. Treatment targets the allergy itself.
Over-the-counter antihistamine eye drops (such as ketotifen, available without prescription) are effective for children and can be used for itch relief during allergy season. Oral antihistamines help when nasal symptoms accompany the eye symptoms. Cool compresses provide quick comfort, and reducing exposure helps: keep windows closed during high-pollen days, wash hands and faces after outdoor play, and launder pillowcases frequently.

Home Care Tips
Regardless of cause, good home care speeds recovery and protects the rest of the family. Clean crusted eyelids gently with a warm, damp cloth, wiping from the inner corner outward, using a fresh section of cloth for each eye. Apply prescribed drops with clean hands: have the child lie back, pull the lower lid down gently to form a pocket, and let the drop fall in without touching the eye with the dropper tip.
Launder pillowcases, towels, and washcloths in hot water daily during the infection. Disinfect frequently touched surfaces like doorknobs and faucet handles. Remind siblings not to share eye drops, towels, or pillows. If your child wears glasses, wipe the frames and nose pads with soap and water — bacteria can linger on them.
School and Daycare Policies
School exclusion policies for pink eye vary, and many have relaxed in recent years. The American Academy of Pediatrics notes that most children with conjunctivitis do not need to be excluded from school unless they have a fever, behavioral changes, or are unable to avoid touching their eyes and spreading secretions.
In practice, many schools still require: for bacterial pink eye, 24 hours on antibiotic treatment before return; for viral pink eye, return when the child feels well enough and discharge is minimal; for allergic pink eye, no exclusion at all since it’s not contagious. Check your specific school or daycare’s written policy — they differ. When in doubt, a note from your pediatrician clarifying the diagnosis and return date resolves most disputes.
When to See a Doctor
Most pink eye is harmless, but certain signs warrant prompt medical attention: severe eye pain (not just irritation), sensitivity to light, blurred vision, intense redness of the entire eye, symptoms that worsen after 2–3 days of treatment, or pink eye in a newborn (always urgent). Also see a doctor if your child has a weakened immune system or if the infection keeps recurring.
The American Academy of Ophthalmology advises that newborns with any eye discharge need immediate evaluation, and contact lens wearers with pink-eye symptoms should remove lenses and seek care promptly. For most school-age children, though, pink eye is a week of crusty mornings and cool compresses — uncomfortable, but very treatable.
