Aditional factors include spaing in lenses not designed for extended wear, using tap water to rinse lenses or cases, and reusing disposable lenses beyond their intended lifespan. Environmental biofilms on contact lens cases act as persistent naguirs, continously inosulating lenses even after disingistion. A 2023 laboratory investition demonate t that consideration
