Conjunctivitis (Pink Eye)

Conjunctivitis, commonly known as pink eye, is an inflammation of the conjunctiva — the thin, clear tissue that covers the white of the eye and lines the inside of the eyelids. It is one of the most common causes of red eye and can affect people of all ages.

Causes

Conjunctivitis can develop due to several factors:

• Viral infection – often associated with colds and upper respiratory infections

• Bacterial infection – can cause thicker discharge and requires antibiotic drops

• Allergic conjunctivitis – triggered by pollen, dust, or pet dander

• Irritants – such as smoke, chlorine, or contact lenses

Symptoms

The signs of conjunctivitis may include:

• Redness in the white part of the eye

• Itching, burning, or gritty sensation

• Excessive tearing or watery discharge

• Thick yellow/green discharge (especially in bacterial conjunctivitis)

• Crusting of eyelashes on waking up

• Sensitivity to light in some cases

Is Conjunctivitis Contagious?

Yes — viral and bacterial conjunctivitis are highly contagious and spread easily through:

• Direct contact with infected individuals

• Touching the eyes with unwashed hands

• Sharing items like towels, bedding, or eye makeup

Allergic conjunctivitis, however, is not contagious.

Diagnosis & Treatment

At Eye Doctor Clinics, our consultant ophthalmologists can examine your eyes to determine the cause of conjunctivitis and recommend the right treatment.

• Viral conjunctivitis: usually clears in 1–2 weeks with proper management and treatment.

• Bacterial conjunctivitis: treated with prescription antibiotic drops or ointment

• Allergic conjunctivitis: controlled with antihistamine drops, oral medication, and avoiding triggers

Preventing Spread

To stop conjunctivitis from spreading:

• Wash hands frequently and avoid touching your eyes

• Do not share towels, bedding, or cosmetics

• Replace contact lenses and cases if contaminated

When to See an Ophthalmologist

Seek immediate medical advice if you have:

• Severe eye pain or sensitivity to light

• Blurred vision that doesn’t improve with blinking

• Symptoms not improving after several days of treatment

• Recurrent or chronic conjunctivitis
