How long does the pink eye bacteria live?

Pink eye. Most pink eyes are caused by viruses with a lifespan of 3 to 10 days. Bacterial infections in adults usually follow trauma and surgery. If bacterial, the infection usually can be overcome in 3-6 days with antibiotic therapy. If present beyond this time, revisit your ophthalmologist to assess.
Up to 7-10 dyays. Most but not all bacteria that cause pink eye are self limiting.Any bacterial pink eye that persists even with treatment should be re-evaluated quickly as to cause.
