What is the primary purpose of disinfection of contact lenses?

The primary purpose of disinfection of contact lenses is to prevent the growth of bacteria, viruses, and fungi. Disinfection is crucial because contact lenses come into direct contact with the eye, which can be susceptible to infections if harmful microorganisms are present. Proper disinfection protocols help ensure that lenses are free from pathogens that could cause eye infections or other complications.

While lens comfort and visual acuity are important considerations for lens wearers, these factors are more related to the lens material and fit rather than the disinfection process itself. Additionally, while extending the lifespan of contact lenses can be a secondary benefit of proper maintenance, the central focus of disinfection is to maintain eye health by reducing the risk of microbial contamination. Thus, the primary purpose of disinfection aligns closely with safeguarding the user's ocular health against infectious agents.
