Pink Eye in Children: Symptoms, Treatment, and When to See a Doctor

What Is Pink Eye?

Pink eye — technically called conjunctivitis — is an inflammation of the conjunctiva, the thin transparent membrane that covers the white of the eye and the inner surface of the eyelids. When this membrane becomes inflamed, blood vessels dilate, giving the eye its characteristic pink or red appearance.

Conjunctivitis is one of the most common eye conditions in childhood. It looks alarming, it spreads quickly in classrooms and daycares, and it almost always has parents wondering: Do we need drops? Do we need to see the doctor? Can my child go to school?

The answers depend on what type of pink eye your child has — and not all types need antibiotics.

Types of Pink Eye in Children

Viral Conjunctivitis (Most Common)

Viral pink eye is the most common form and is often associated with a cold or upper respiratory infection. It usually starts in one eye and may spread to the other.

Key features:

• Watery or clear discharge
• Redness
• Gritty or irritated feeling
• Often associated with cold symptoms (runny nose, mild fever)
• Very contagious

Treatment: Viral pink eye does NOT need antibiotic eye drops — antibiotics don't work against viruses. It typically resolves on its own within 7–14 days with supportive care.

Bacterial Conjunctivitis

Bacterial pink eye is more likely to cause thicker, yellowish-green discharge and crustiness that glues the eye shut overnight.

Key features:

• Yellow or green thick discharge
• Eyelids stuck together in the morning
• Redness, typically more pronounced than viral
• Can affect one or both eyes
• Very contagious

Treatment: Antibiotic eye drops or ointment are typically prescribed. These speed recovery and reduce contagiousness. Many cases of bacterial conjunctivitis also resolve on their own within 5–7 days without antibiotics, but most schools require treatment before return.

Allergic Conjunctivitis

Caused by allergens (pollen, pet dander, dust mites). Not contagious.

Key features:

• Itching — often intense
• Watery discharge
• Both eyes affected
• Associated with other allergy symptoms (runny nose, sneezing)
• Tends to be seasonal or associated with allergen exposure

Treatment: Antihistamine eye drops, oral antihistamines, cold compresses, and allergen avoidance. No antibiotics needed.

Chemical or Irritant Conjunctivitis

Caused by exposure to chlorine, smoke, shampoo, or other irritants. Not contagious and typically resolves quickly after the irritant is removed.

Home Care for Pink Eye

While waiting for an appointment or treating viral/mild bacterial pink eye at home:

• Warm compresses — A warm, damp cloth gently pressed over the closed eye for a few minutes can soothe irritation and help loosen crusty discharge. Use a fresh cloth for each eye to avoid spreading infection.
• Clean the discharge — Gently wipe discharge from the inner corner of the eye outward with a clean, damp cotton ball or cloth. Never wipe from the outer to inner corner.
• Wash hands frequently — Pink eye spreads easily through hand-to-eye contact. Frequent handwashing is the single most important prevention measure.
• Don't touch or rub the eyes — Teach your child not to rub their eyes, which spreads the infection.
• Don't share towels, pillowcases, or washcloths during active infection.

Pink Eye That Doesn't Improve

If your child's pink eye symptoms are not improving or you're unsure whether antibiotic drops are needed, a sick visit at Hummingbird Pediatrics can help clarify the diagnosis and get your child the right treatment quickly. We offer same-day sick appointments for children in Robbinsville and surrounding communities.

When Can My Child Return to School?

School and daycare policies on pink eye vary. Here are the general guidelines:

• Viral conjunctivitis — Children can often return to school once symptoms are improving and they practice good handwashing. Check your school's specific policy.
• Bacterial conjunctivitis — Most schools require children to be on antibiotic drops for at least 24 hours before returning, and discharge should be improving.
• Allergic conjunctivitis — No time out of school required — it's not contagious.

If your child needs a doctor's note to return to school, we can provide one at their visit.

Is Pink Eye Contagious?

Viral and bacterial conjunctivitis are both highly contagious. They spread through direct contact with eye secretions, touching contaminated surfaces and then touching the eyes, and (for viral) respiratory droplets from coughing and sneezing. Allergic conjunctivitis is not contagious.

Children with contagious pink eye should avoid touching their eyes, wash their hands frequently, not share towels or pillows, and follow their school's return policy to avoid spreading it to classmates.

Frequently Asked Questions

Does pink eye in children always need antibiotic eye drops?

No — most pink eye in children is caused by viruses, which do not respond to antibiotics. Viral pink eye resolves on its own within 7–14 days with supportive care. Antibiotic drops are prescribed for bacterial pink eye, which typically causes thick yellow-green discharge and crusting. Allergic pink eye requires antihistamines, not antibiotics.

How can I tell if my child's pink eye is viral or bacterial?

Bacterial pink eye typically causes thick, yellow or green discharge that crusts and glues the eye shut overnight. Viral pink eye usually causes watery or clear discharge and is more often associated with cold symptoms. Allergic pink eye causes intense itching and affects both eyes. It can be difficult to tell them apart without an exam — your pediatrician can help determine the type and whether antibiotics are needed.

How long is pink eye contagious in children?

Bacterial pink eye is contagious until the child has been on antibiotic eye drops for at least 24 hours and discharge is improving. Viral pink eye can be contagious for as long as symptoms are present, which may be 7–14 days. Good handwashing significantly reduces the spread. Allergic conjunctivitis is not contagious.

When should I take my child to the doctor for pink eye?

See your pediatrician if your child is a newborn (any age under 1 month), has eye pain beyond irritation, has vision changes, has significant swelling around — not just in — the eye, has no improvement after several days, or if you need a return-to-school note or antibiotic drops per your school's policy.
