Final answer:
Acanthamoeba spp. is the pathogen associated with contact lens wear, causing a serious eye infection known as Acanthamoeba keratitis, which can lead to severe corneal damage and vision loss.
Step-by-step explanation:
Among the pathogens listed, D) Acanthamoeba spp. is associated with contact lens wear. Acanthamoeba keratitis is a serious eye infection that can affect contact lens users. This parasitic infection, which is often a result of improper disinfection of contact lenses or swimming while wearing them, can lead to severe corneal damage, vision impairment, or even blindness if not promptly treated.
Contact lens wearers are at a greater risk for developing keratitis, including infections caused by Acanthamoeba, because lenses can provide a space for pathogens like Acanthamoeba and bacteria to thrive if not cared for properly. Prevention includes thorough and proper disinfection of contact lenses to minimize the risk of infection.
