Infectious forms of conjunctivitis can be spread rather easily which makes personal hygiene one of the biggest concerns when dealing with the disease. This will help ensure that the infection does not spread to others or to your other eye, if not already infected. Close personal contact increases the risk of a spread, so if you work in an environment or at a task that involves close contact with others it may be best to simply stay home for a few days. While conjunctivitis does not impair functioning in most cases, it can in rare cases pose a risk especially if the presence of any other health condition causes complications to arise. Make sure that you avoid scratching or touching your eyes and always make sure you wash your hands or use a hand sanitizer after touching the eyes. Surfaces that could be contaminated should also be disinfected to avoid spreading the infection. Never share towels or handkerchiefs, and make it a point to throw away tissues after each use.
