Soft Contact Lens Complications Practice Test

Daily disposable wear lowers risk because you replace the lens every day, eliminating the cleaning, disinfection, and case storage steps that can introduce or harbor microbes. With no cleaning solutions or stored lenses to contaminate, handling is minimized and there’s no opportunity for contaminants to accumulate on the lens surface. This reduces the chance of microbial keratitis developing and, if infection occurs, tends to limit its severity since the lens surface isn’t laden with deposits or biofilms that can harbor pathogens. The other options don’t offer the same reduction in contamination risk: weekly wear still requires cleaning and storage, color-tinted lenses don’t change infection risk, and rigid gas permeable lenses don’t provide the same minimizing effect on contamination from handling and storage as daily disposables.
