What is Conjunctivitis?

Conjunctivitis, also called pink eye, is an infection or swelling of the thin layer covering the white part of your eye. This layer is called the conjunctiva. When it gets inflamed, your eye may look red or pink. Many people get conjunctivitis at least once in their lives. Although it can be uncomfortable, it is usually not serious. However, it spreads easily, especially among children.

Common Symptoms of Conjunctivitis

Conjunctivitis has several signs that are easy to spot. For example, you may notice:

Red or pink color in one or both eyes

Itchy or burning feeling in the eyes

Watery or thick discharge from the eyes

Crust on the eyelids, especially after sleep

Increased tearing

Feeling like something is stuck in your eye

Sensitivity to light

Sometimes, symptoms start in one eye and move to the other. Because conjunctivitis can look like other eye problems, it is important to watch for these signs.

Causes of Conjunctivitis

There are several reasons why you might get conjunctivitis. Most often, it is caused by:

Viruses (like those that cause the common cold)

Bacteria (such as Staphylococcus or Streptococcus)

Allergies (to pollen, dust, or pet dander)

Chemicals (like chlorine in swimming pools)

Foreign objects (such as dirt or contact lenses)

Viral and bacterial conjunctivitis are very contagious. On the other hand, allergic conjunctivitis is not spread from person to person.

How is Conjunctivitis Diagnosed?

Doctors can often diagnose conjunctivitis by looking at your eyes and asking about your symptoms. Sometimes, they may:

Ask if you have been near someone with pink eye

Check for allergies or recent illnesses

Take a small sample of eye discharge for testing

Usually, no special tests are needed. However, if symptoms are severe or do not improve, your doctor may do more tests to rule out other eye problems.

Treatment Options for Conjunctivitis

Treatment depends on the cause of conjunctivitis. For example:

Viral conjunctivitis: Usually goes away on its own in 1–2 weeks. Use cool compresses and keep your eyes clean.

Bacterial conjunctivitis: Doctors may prescribe antibiotic eye drops or ointment. This helps clear the infection faster.

Allergic conjunctivitis: Avoid triggers if possible. Doctors may suggest allergy eye drops or oral medicines.

While at home, you can:

Wash your hands often

Avoid touching or rubbing your eyes

Use a clean towel for your face

Do not share pillows or eye makeup

Never use someone else’s eye drops or medicine. If you wear contact lenses, stop using them until your doctor says it is safe.

Prevention Tips and Lifestyle Guidance

Because conjunctivitis spreads easily, good habits can help protect you and others. For instance:

Wash your hands with soap and water often

Do not touch your eyes with dirty hands

Change pillowcases and towels regularly

Clean or replace contact lenses as directed

Stay home from school or work if you have pink eye

Avoid sharing personal items like towels or makeup

By following these tips, you can lower your risk of getting or spreading conjunctivitis. In addition, keeping your living space clean helps prevent eye infections.

When to See a Doctor

Most cases of conjunctivitis are mild. However, you should see a doctor if you:

Have severe pain in your eye

Notice changes in your vision

See a lot of swelling or redness

Have symptoms that last more than one week

See yellow, green, or thick pus from your eye

Have a weakened immune system

Early treatment for conjunctivitis can prevent complications and help you feel better much sooner. Recognising symptoms early and seeking timely care ensures quick recovery and protects those around you from infection.
