Red eye in children

Overview

Red eye in children means the white part of the eye looks red or pink. It is usually caused by irritation, infection, or allergy and often clears up on its own.

Yes, red eye is one of the most common reasons parents take their child to the doctor.

It can affect children of any age, from babies to teenagers.

Symptoms

Common symptoms

• Redness in the white part of the eye
• Watery or sticky discharge
• Itching or a gritty feeling
• Swollen eyelids

Symptoms in children

• Rubbing eyes a lot
• Crusty eyelids, especially when waking up
• Discharge that may be clear, white, or yellow
• Sensitivity to light

Symptoms in older adults

• Red eye in older adults may be due to dry eye or other age-related conditions

Causes

Main causes

• Viral infection (viral conjunctivitis) – often with a cold
• Bacterial infection (bacterial conjunctivitis) – causes sticky, yellow discharge
• Allergic reaction (allergic conjunctivitis) – triggered by pollen, dust, or pet dander
• A foreign object in the eye, like dirt or an eyelash
• Blocked tear duct in babies

Risk factors

• Close contact with someone who has pink eye (conjunctivitis)
• Seasonal allergies
• Poor hand hygiene
• Sharing towels, pillows, or eye makeup

When to see a doctor

See a doctor urgently if:

• Any sign of eye injury or chemical splash
• Severe pain that does not stop
• Vision changes or sensitivity to light that worries you
• Child is very unwell or has a high fever

Book a routine appointment if:

• Redness that lasts more than a few days
• Mild discharge that does not clear
• Child keeps rubbing their eyes and seems uncomfortable

Diagnosis

A doctor will look at your child's eye, ask about symptoms and any contact with sick people or allergens.

Tests that may be done

• The doctor may gently wipe the inside of the lower eyelid to test the discharge for bacteria (rarely needed).

What to expect at your appointment

The examination is quick and painless. The doctor may use a small light to check the eye. They will tell you the likely cause and whether treatment is needed.

Treatment

Treatment depends on the cause. Most children get better without medicine. For bacterial infections, the doctor may prescribe antibiotic eye drops or ointment. Allergic eye infections may be helped by allergy medicines. Viral infections usually need no treatment.

Self-care at home

• Clean the eye gently with a clean, damp cloth – use a fresh cloth for each eye
• Apply a warm compress (a clean cloth soaked in warm water) to the closed eye for a few minutes
• Keep your child home from school or daycare if they have sticky discharge (until it improves)
• Wash hands often and do not share towels, pillows, or eye drops
• Encourage your child not to rub their eyes

Medical treatments

A doctor may prescribe antibiotic eye drops or ointment for bacterial conjunctivitis. For allergic causes, they might recommend antihistamine eye drops. Always follow the doctor's instructions. Never share eye medicines.

When is surgery considered?

Surgery is rarely needed. It may be considered for a blocked tear duct that does not improve by age one.

Living with this condition

Red eye usually gets better in a few days to a week. Keep the eye clean, wash hands, and avoid sharing personal items. Your child can return to school when the discharge stops or after 24 hours of treatment (if prescribed).

Lifestyle tips

• Teach your child to wash hands frequently, especially after touching their eyes
• Do not let your child share makeup, face cloths, or eye drops
• If allergies are a trigger, try to reduce exposure to pollen, dust, and pet dander

Diet and exercise

No special diet or exercise changes are needed. A balanced diet supports overall health.

Mental health and emotional wellbeing

Red eye can be unsettling for both child and parent, but it is usually short-lived. Most children feel fine once the eye is better. If your child seems very anxious, talk to your doctor or health visitor.

Prevention

Good hand hygiene and avoiding close contact with infected people can reduce the risk. Do not share towels, pillows, or eye makeup. Teach children not to rub their eyes.

Vaccines

Vaccines against measles, rubella, and chickenpox can prevent some infections that cause red eye.

Screening programmes

There is no routine screening for red eye in children.

Complications

If left untreated

• Bacterial infection may spread to deeper parts of the eye (rare)
• Severe allergic reactions can cause eye swelling and discomfort
• In very rare cases, untreated infection can lead to vision problems

Long-term outlook

The outlook is excellent. Almost all children with red eye recover fully without any lasting effects. With simple care and sometimes treatment, symptoms quickly improve.
