Pink Eye (Conjunctivitis) in Children — Symptoms, Treatment, and Contagion

Your child wakes up in the morning with crusted eyes and yellow discharge in the corner of their eye. The eye is red and the little one is rubbing it in frustration. Pink eye is one of the most common reasons parents take their child to the doctor, and most children experience at least one episode during their early years.

The good news is that pink eye in children is almost always harmless and clears up on its own. But it's important to know when to see a doctor, how to relieve symptoms, and what applies for daycare attendance.

What Is Pink Eye?

Pink eye — or conjunctivitis, as it's called medically — is an inflammation of the conjunctiva, the thin membrane that covers the white of the eye and the inside of the eyelids. The inflammation makes the eye red, irritated, and often produces discharge or increased tearing.

According to major health organizations, conjunctivitis does not affect the eye itself and poses no threat to vision. It can be compared to a cold in the eye — uncomfortable, but usually completely harmless.

Pink eye is highly contagious and is transmitted directly through touching (fingers rubbing the eye and then touching something else) or indirectly through towels and pillows. This is why it spreads quickly in daycares.

Types of Pink Eye in Children

There are three main types of pink eye, and it's useful to know the difference because treatment varies.

Bacterial Conjunctivitis

Bacterial conjunctivitis is the most common type in children. It often occurs alongside respiratory infections or ear infections.

Characteristics:

• Yellowish or greenish discharge from the eye
• Crusted eyes after sleep, especially in the morning
• Usually starts in one eye, spreads to the other within 1-2 days
• Eyelids may become swollen
• Incubation period: 1-2 days

Viral Conjunctivitis

Adenovirus is the most common cause of viral conjunctivitis and the type that most often causes outbreaks in daycares. Viral conjunctivitis often comes alongside a cold.

Characteristics:

• Clear, watery discharge (not thick discharge)
• More burning and discomfort than bacterial conjunctivitis
• Red eyes
• Often concurrent cold, stuffy nose, or cough
• Incubation period: 5-14 days
• Children remain contagious even during treatment

Allergic Conjunctivitis

Allergic conjunctivitis is caused not by infection but by an allergic reaction. This type rarely occurs in very young children but can appear in children from about 2-3 years of age.

Characteristics:

• Itchy eyes (child rubs a lot)
• Affects both eyes simultaneously
• Often seasonal (pollen) or triggered by pet dander
• Often accompanied by stuffy nose and sneezing
• Not contagious

Symptoms of Pink Eye in Children and Babies

Symptoms can vary somewhat with the child's age, but the most common signs are:

• Red eyes — the white of the eye becomes redder and more inflamed than usual
• Discharge — yellow, green, or clear, depending on type
• Crusted eyes — especially after sleep
• Increased tearing — eyes water more than usual
• Irritation — child rubs or scratches at eyes
• Feeling of something in the eye — older children describe it as "sand in the eye"
• Swollen eyelids — with more severe infection

Symptoms in Babies

Babies cannot say that their eye hurts or is irritated. Watch for:

• Rubbing eye or face frequently
• More fussy and irritable than usual
• Discharge or crust in the corner of the eye
• One or both eyes look sticky

Pink Eye in Newborns — Take Seriously

Pink eye in newborns (first 4 weeks of life) is a special category requiring extra attention. Conjunctivitis in newborns should always be evaluated by a doctor.

Blocked Tear Duct

The most common cause of discharge in infants is not pink eye but a blocked tear duct. This occurs in about 1 in 20 infants, and is usually only in one eye.

How it differs from pink eye:

• The white of the eye does not turn red (just some discharge)
• Only in one eye
• Returns after cleaning

Management: Gently massage the area below the inner corner of the eye with one finger. The tear duct usually opens on its own during the first year. If there are frequent, one-sided eye infections, contact your doctor.

Bacterial Conjunctivitis in Newborns

Newborns can develop eye infections after exposure to bacteria in the birth canal. In rare cases, this can involve chlamydia or gonorrhea.

The following applies for newborns:

• E. coli is most common in the first two days
• Gonococcal infection causes heavy discharge ("creamy") typically at 1-5 days of age
• Chlamydia typically appears after 5 days of age

Home Treatment

Most cases of pink eye in children clear up on their own without specific treatment. Here's what you can do at home:

Cleaning the Eyes — the Most Important Step

1. Wash your hands thoroughly before touching the child's eyes
2. Dampen a clean cloth or cotton pad with lukewarm, clean water or sterile saline
3. Wipe from outer to inner corner to prevent spreading discharge
4. Use a new cloth for each eye to avoid infecting the healthy eye
5. Repeat several times daily — especially in the morning when eyes may be crusted

Sterile saline eye drops are cleansing and make it easier to remove dried discharge. They are available over the counter at pharmacies.

What About Antibiotics?

Doctors are cautious with antibiotics for pink eye, in line with guidelines to limit antibiotic resistance.

Facts about antibiotics and pink eye:

• Pink eye usually clears up on its own within 1-2 weeks
• Antibiotics provide only a modest clinical benefit compared to placebo for common bacterial conjunctivitis
• Antibiotics have no effect on viral conjunctivitis
• A doctor may give a "wait-and-see prescription" that you fill only if there's no improvement

When does a doctor prescribe antibiotics?

• Severe pink eye with heavy discharge and red eye
• When the child is clearly unwell
• If there's no improvement after a few days of home treatment
• Always for pink eye in newborns (under 4 weeks)

If treatment is started, eye drops containing chloramphenicol or fusidic acid (Fucithalmic) are typically used. Both eyes should be treated. Continue treatment for 2 days after symptoms have resolved. If antibiotics don't show effect within 3-4 days, see the doctor again.

Allergic Conjunctivitis

For allergic conjunctivitis, cold compresses and artificial tears can relieve mild symptoms. For older children (6+), allergy eye drops and antihistamines are available over the counter. For younger children, consult a doctor.

When Should You See a Doctor?

Contact your doctor or urgent care in these situations:

Contact doctor for:

• Pink eye in newborns (first 4 weeks of life) — always see a doctor
• The white of the eye becomes red and the child seems unwell
• Discharge for several days without signs of improvement
• Heavy discharge with lots of yellow or green secretion
• Pain — common pink eye causes little pain; pain may indicate something else
• Light sensitivity or changes in vision
• Swelling or redness around the eye (not just in the eye)
• No improvement after 3-4 days of antibiotic treatment

Call emergency services if:

• Sudden one-sided red and painful eye with reduced vision
• Suspected chemicals or foreign body in the eye that won't rinse out

Contagion and Daycare — How Long to Stay Home?

This is the question most parents ask: can my child go to daycare with pink eye? Guidelines from public health authorities are clear:

Daycare Guidelines

Important to know:

• It is the parents who decide whether the child should be examined by a doctor
• Daycare staff cannot require that children with pink eye be treated with eye drops before returning
• When in doubt, the daycare can discuss it with the parents or consult the local public health nurse

How Long Is Pink Eye Contagious?

• Bacterial conjunctivitis: The risk of contagion decreases quickly after starting antibiotic treatment
• Viral conjunctivitis: The child is contagious throughout the illness — often 5-10 days — regardless of treatment

How Daycares Limit Spread

• Extra focus on hand hygiene during outbreaks
• Wiping discharge from children's eyes with clean water
• Avoid sharing towels and washcloths
• Teaching children not to rub their eyes and then touch others

Prevention

You can't prevent all cases of pink eye, but you can reduce the risk:

• Good hand hygiene — wash hands frequently
• Teach the child not to rub their eyes — easier said than done with toddlers, but it helps
• Own towel — the person with pink eye should have their own towel
• Wash bedding and towels at 60°C (140°F) during active infection
• Change pillowcases frequently during illness
• Clean toys that the child has had near their face

For children with allergic conjunctivitis:

• Avoid known allergens where possible
• Keep windows closed during pollen season
• Don't dry clothes outside during pollen season
• Talk to your doctor about preventive allergy treatment

Frequently Asked Questions

Can pink eye spread to the whole family?

Yes, pink eye spreads easily within a household. Wash hands frequently, use separate towels, and avoid sharing bedding. Bacterial conjunctivitis is contagious as long as there is discharge, while viral conjunctivitis is contagious throughout the illness (5-10 days). Adults can also be affected.

How long does pink eye last in children?

Pink eye typically lasts 1-2 weeks. Viral conjunctivitis clears up on its own after 5-10 days. Bacterial conjunctivitis can last just as long without treatment, but antibiotic treatment can shorten the course by a few days. Most children are noticeably better after 3-5 days.

Is pink eye dangerous for vision?

Common pink eye does not threaten vision. Pink eye affects the membrane around the eye, not the eye itself. The exception is rare cases where the infection is caused by herpes virus or spreads to the cornea (keratitis). Pink eye in newborns can in rare cases cause complications if caused by gonorrhea or chlamydia — this is why it should always be evaluated by a doctor.

Can I use breast milk in my baby's eyes?

Breast milk in the eyes is an old home remedy. Breast milk contains antibodies, but it hasn't been proven to be more effective than sterile saline. It is harmless to try, but does not replace medical treatment for severe pink eye.

Should I keep my child home from daycare with pink eye?

According to public health guidelines, there's no reason to keep the child home for mild to moderate pink eye as long as their general condition is good. The child should stay home for severe pink eye with heavy discharge, or reduced general condition. If antibiotics are started, the child can return to daycare the day after starting treatment.
