Wash your hands often with soap and water. This is the single most important thing you can do to prevent the spread of conjunctivitis.
Avoid touching your eyes. This may seem obvious, but it's important to remember not to touch your eyes, even if they're not feeling irritated.
Use disposable tissues to wipe away any discharge from your eyes. Throw the tissues away immediately after use.
Avoid sharing towels, pillowcases, or other personal items with someone who has conjunctivitis.
Wear sunglasses when you're outdoors, especially if it's windy or dusty. This will help protect your eyes from irritants that can trigger conjunctivitis.
If you do develop conjunctivitis, see your doctor right away. They can prescribe eye drops or ointment to help relieve the symptoms.
If you wear contact lenses, take them out and clean them thoroughly according to the manufacturer's instructions. You may also want to consider wearing glasses instead of contacts until your conjunctivitis clears up.
