British Columbia Specific Information
Pinkeye, also called conjunctivitis, is a common childhood illness. Pinkeye usually makes the whites of your eyes turn red or pink, and can cause them to tear or become itchy. Pus can make your eyelids sticky, especially when you sleep. For more information about pinkeye, see HealthLinkBC File #82 Pinkeye (Conjunctivitis).

Pink eye (also called conjunctivitis) is redness and swelling of the conjunctiva, the mucous membrane that lines the eyelid and eye surface. The lining of the eye is usually clear. If irritation or infection occurs, the lining becomes red and swollen. See pictures of a normal eye and an eye with conjunctivitis.
Pink eye is very common. It usually is not serious and goes away in 7 to 10 days without medical treatment.
Most cases of pink eye are caused by:
- Infections caused by viruses or bacteria.
- Dry eyes from lack of tears or exposure to wind and sun.
- Chemicals, fumes, or smoke (chemical conjunctivitis).
Viral and bacterial pink eye are contagious and spread very easily. Since most pink eye is caused by viruses for which there is usually no medical treatment, preventing its spread is important. Poor handwashing is the main cause of the spread of pink eye. Sharing an object, such as a face cloth or towel, with a person who has pink eye can spread the infection. For more information, see Prevention.
Viral pink eye
Viral pink eye is often caused by an adenovirus, which is a common respiratory virus that can also cause a sore throat or upper respiratory infection. The herpes virus can also cause viral pink eye.
Symptoms of viral pink eye include:
- Redness in the white of the eye.
- Swelling of the eyelids.
- Itching or burning feeling of the eyelids.
- Swollen and tender areas in front of the ears.
- A lot of tearing.
- Clear or slightly thick, whitish drainage.
Viral pink eye symptoms usually last 5 to 7 days but may last up to 3 weeks and can become ongoing or chronic.
Pink eye may be more serious if you:
- Have a condition that decreases your body's ability to fight infection (impaired immune system).
- Have vision in only one eye.
- Wear contact lenses.
If the pink eye is caused by a virus, the person can usually return to daycare, school, or work when symptoms begin to improve, typically in 3 to 5 days. Medicines are not usually used to treat viral pink eye, so it is important to prevent the spread of the infection. Pink eye caused by a herpes virus, which is rare, can be treated with an antiviral medicine. Home treatment of viral pink eye symptoms can help you feel more comfortable while the infection goes away.
Bacterial pink eye
An infection may develop when bacteria enter the eye or the area around the eye. Some common infections that cause pink eye include:
Symptoms of bacterial pink eye include:
- Redness in the white of the eye.
- Gray or yellow drainage from the eye. This drainage may cause the eyelashes to stick together.
- Mild pain.
- Swelling of the upper eyelid, which may make the lid appear to droop (pseudoptosis).
Bacterial pink eye may cause more drainage than viral pink eye. Bacterial infections usually last 7 to 10 days without antibiotic treatment and 2 to 4 days with antibiotic treatment. The person can usually return to daycare, school, or work 24 hours after an antibiotic has been started if symptoms have improved. Prescription antibiotic treatment usually kills the bacteria that cause pink eye.
Red eye is a more general term that includes not only pink eye but also many other problems that cause redness on or around the eye, not just the lining. Pink eye is the main cause of red eye. Red eye has other causes, including:
- Foreign bodies, such as metal or insects. For more information, see the topic Objects in the Eye.
- Scrapes, sores, or injury to or infection of deeper parts of the eye (for example, uveitis, iritis, or keratitis). For more information, see the topic Eye Injuries.
- Glaucoma. For more information, see the topics Eye Problems, Non-Injury and Glaucoma.
- Infection of the eye socket and areas around the eye. For more information, see the topic Eye Problems, Non-Injury.
Swollen, red eyelids may also be caused by styes, a lump called a chalazion, inflammation of the eyelid (blepharitis), or lack of tears (dry eyes). For more information, see the topics Styes and Chalazia and Eyelid Problems (Blepharitis).

Home treatment for pink eye will help reduce your pain and keep your eye free of drainage. If you wear contacts, remove them and wear glasses until your symptoms have gone away completely. Thoroughly clean your contacts and storage case.
Cold compresses or warm compresses (whichever feels best) can be used. If an allergy is the problem, a cool compress may feel better. If the pink eye is caused by an infection, then a warm, moist compress may soothe your eye and help reduce redness and swelling. Warm, moist compresses can spread infection from one eye to the other. Use a different compress for each eye, and use a clean compress for each application.
When cleaning your eye, wipe from the inside (next to the nose) toward the outside. Use a clean surface for each wipe so that drainage being cleaned away is not rubbed back across the eye. If tissues or wipes are used, make sure they are put in the trash and are not allowed to sit around. If face cloths are used to clean the eye, put them in the laundry right away so that no one else picks them up or uses them. After wiping your eye, wash your hands to prevent the pink eye from spreading.
After pink eye has been diagnosed:
- To learn how to prevent the spread of pink eye, see Prevention.
- Do not go to daycare or school or go to work until pink eye
- If the pink eye is caused by a virus, the person can usually return to daycare, school, or work when symptoms begin to improve, typically in 3 to 5 days. Medicines are not usually used to treat viral pink eye, so preventing its spread is important. Home treatment of the symptoms will help you feel more comfortable while the infection goes away.
- If the pink eye is caused by bacteria, the person can usually return to daycare, school, or work after the infection has been treated for 24 hours with an antibiotic and symptoms are improving. Prescription antibiotic treatment usually kills the bacteria that cause pink eye.
- Use medicine as directed. Medicine may include eyedrops and eye ointment.
For pink eye related to allergies, antihistamines, such as loratadine (Claritin) or cetirizine (Zyrtec), may help relieve your symptoms. Don't give antihistamines to your child unless you've checked with the doctor first.
Symptoms to watch for during home treatment
Call your doctor if any of the following occur during home treatment:
- Eye pain continues or increases.
- Sensitivity to light (photophobia) develops.
- Signs of an infection develop.
- Symptoms become more severe or frequent.
If you wear contacts, be sure to remove your contacts when your eye problem starts.
Pink eye is spread through contact with the eye drainage, which contains the virus or bacteria that caused the pink eye. Touching an infected eye leaves drainage on your hand. If you touch your other eye or an object when you have drainage on your hand, the virus or bacteria can be spread.
The following tips help prevent the spread of pink eye.
- Wash your hands before and after:
- Touching the eyes or face.
- Using medicine in the eyes.
- Do not share eye makeup.
- Do not use eye makeup until the infection is fully cured, because you could reinfect yourself with the eye makeup products. If your eye infection was caused by bacteria or a virus, throw away your old makeup and buy new products.
- Do not share contact lens equipment, containers, or solutions.
- Do not wear contact lenses until the infection is cured. Thoroughly clean your contacts before wearing them again.
- Do not share eye medicine.
- Do not share towels, linens, pillows, or handkerchiefs. Use clean linens, towels, and face cloths daily.
- Wash your hands and wear gloves if you are looking into someone else's eye for a foreign object or helping someone else apply an eye medicine.
- When in the wind, heat, or cold, wear eye protection to prevent eye irritation.
- Wear safety glasses when working with chemicals.
