What is the life span of pink eye germs?

The germs that cause pink eye, or conjunctivitis, can vary in lifespan depending on the type. Viral and bacterial pathogens can survive on surfaces for several hours to a few days, while allergens and irritants do not have a "lifespan" in the same sense. Proper hygiene, such as washing hands and disinfecting surfaces, can help minimize the risk of transmission.
