Conjunctivitis

Key facts

• Conjunctivitis is inflammation of the thin membrane lining the inner eyelid and covering the white of the eye, causing redness, watering, discharge, and a gritty or itchy feeling.
• The three main causes look different: bacterial conjunctivitis produces thick yellow or green discharge, viral conjunctivitis brings watery discharge alongside cold symptoms, and allergic conjunctivitis causes intense itching.
• Most cases clear within one to two weeks. Anti-inflammatory drops such as those containing ketorolac help allergic or inflammatory cases; the eye care range covers antibiotic and other options for bacterial cases.
• See a doctor if vision changes, pain is severe, symptoms persist beyond a week, or a newborn develops any eye discharge.

What sets off conjunctivitis

Bacterial conjunctivitis is the most common infectious form and produces thick yellow or green discharge, often causing the eyelids to stick together overnight. Viral conjunctivitis typically follows a cold or upper respiratory infection and causes watery rather than sticky discharge; it spreads easily in schools and workplaces. Allergic conjunctivitis brings intense itching with watery eyes and is triggered by dust mites, pollen, or pet dander. Eye drops in the eye care range address each of these presentations differently, so identifying the cause matters.

Easing symptoms and knowing when to get help

Cool compresses and rinsing the eye with clean water relieve discomfort while the infection runs its course. Avoid touching or rubbing the eyes, and replace contact lenses and any eye make-up used around the time symptoms began. Bacterial cases are sometimes treated with antibiotic drops; inflammatory or allergy-driven irritation can be managed with anti-inflammatory options such as those containing ketorolac.

When to see a doctor

Seek prompt attention if vision changes, pain is severe, symptoms do not improve after a week, or a newborn develops any eye discharge. These signs need clinical assessment rather than self-care.
