Conjunctivitis

Inflammation of the conjunctiva, the thin membrane that covers the white of the eye and the inside of the eyelids. Usually harmless.

Book

Contact us quickly if you have pain, reduced vision, sensitivity to light or if you wear contact lenses.

Three types

Bacterial

Yellow or greenish pus, and the eyelids stick together in the morning. Often clears by itself within a week.

Viral

Red, watery eye, often after a cold. Very contagious and can last 1–3 weeks.

Allergic

Itching, redness and swelling of both eyes, often in the pollen season or after contact with animals.

What you can do yourself

  • Clean your eyes with lukewarm water and a clean tissue
  • Wash your hands often and do not share towels
  • Take a break from contact lenses and eye make-up
  • For allergy, antihistamine eye drops from the pharmacy can help

For bacterial conjunctivitis, antibiotic eye drops can shorten the course.
