Conjunctivitis is inflammation of the thin, clear layer covering the white of the eye and the inside of the eyelids. It makes the eye red, sore or sticky and is very common.
Common types
- Viral: watery, red eyes, often with a cold; highly contagious
- Bacterial: sticky yellow or green discharge
- Allergic: itchy, watery, red eyes, often in both eyes and linked to hay fever
Common symptoms
- Red or pink eye
- Gritty or burning feeling
- Watering or sticky discharge, eyelids stuck together on waking
- Swollen eyelids
Self-care
Clean the eyelids gently with cooled boiled water and cotton wool, use a clean cloth for each eye, wash hands often and avoid sharing towels. Remove contact lenses until the eye has fully settled. Many cases improve within one to two weeks.
Assessment
Conjunctivitis is usually diagnosed from your symptoms and an examination of the eye. Other eye conditions can look similar, so an assessment is advised if you are unsure or things are not improving.
When to seek urgent help
Seek same-day help if you have eye pain, sensitivity to light, blurred vision, a very red eye, or if you wear contact lenses and your eye is painful. Use NHS 111, your GP, an urgent eye service or A&E.
