Pink Eye (Conjunctivitis)

🌿 Overview

Pink eye is inflammationThe body's natural response to injury — like redness, swelling, or heat around a sore spot. More → of the clear layer over the eye. Viral and bacterial kinds are very contagious, so careful hand-washing and not sharing towels matter as much as soothing care. Warm and cool compresses, gentle saline rinses, and rest help — and a doctor should confirm the cause if there's a lot of pus or any pain.

Pink eye is an inflammation of the conjunctiva — the clear, thin layer that covers the white of the eye and lines the inside of the eyelids. When it gets irritated or infected, those tiny blood vessels swell and the eye looks pink or red, feels itchy or gritty, and often waters. There are a few different causes. Viruses are the most common and are very catching; bacteria can cause it too, often with thick, sticky discharge; and allergies or irritants (pollen, smoke, chlorine, makeup) can inflame the eye without any infection at all. Telling them apart matters, so it is wise to let a doctor or nurse confirm what is going on, especially if there is a lot of pus. The biggest thing to know is that the infectious kinds spread easily — through hands, shared towels, and pillows. Gentle care soothes the eye, but careful hand-washing and not sharing are just as important so it doesn't pass to others or to your other eye.

Common signs

• Pink or red color in the white of the eye
• Itching, grittiness, or a burning feeling
• Watering, or thick discharge that can crust the lashes
• Eyelids stuck together after sleep
• Swollen, irritated eyelids
• Often spreads from one eye to the other

🔎 Why it happens

Common causes and triggers — spotting yours is often the first step to relief.

• A **virus** — the most common cause, and very contagious
• **Bacteria**, often with thick yellow or green discharge
• **Allergens** like pollen, dust, or pet dander (often both eyes, itchy)
• **Irritants** — smoke, chlorine in pools, fumes, or makeup
• Touching the eyes with unwashed hands or sharing towels and pillows

✅ What to do

Gentle, practical steps you can take at home — start at the top.

1. Gently lay a warm compress over the closed eye to loosen and wipe away crusts, using a clean cloth each time.
2. For itching and comfort, a cool compress held lightly on the eye can soothe — never press on the eyeball.
3. Wash your hands often and well, before and after touching your eyes, to keep it from spreading.
4. Rinse the eye gently with clean saline (sterile salt-water eye rinse) to clear discharge.
5. Don't share towels, washcloths, or pillows, and use a fresh cloth for each wipe.
6. Throw out old eye makeup, skip makeup and contact lenses until it clears, and avoid rubbing the eyes.
7. A cooled, strained charcoal poultice over the closed lid overnight is a traditional soothing help — keep it loose so there's no pressure on the eyeball, and use a fresh cloth, disposing of it afterward.
8. Get plenty of rest and drink water while your body heals.
