The escalating prevalence of contact lens use for both vision correction and cosmetic enhancement underscores the imperative for a comprehensive assessment of their influence on ocular health. Traditional hydrogel contact lenses, despite offering exceptional comfort and oxygen permeability, are prone to microbial adhesion, thereby presenting a considerable risk of ocular infections. This review centers on the effectiveness and performance of antibacterial hydrogel contact lenses formulated with diverse antimicrobial agents, encompassing metal nanoparticles, carbon-based nanomaterials, and bio-based substances. We delve into the mechanisms through which these materials impede microbial proliferation, augment biocompatibility, and sustain oxygen circulation within the ocular microenvironment. A meticulous analysis of various antibacterial materials, their modes of action, and their relative efficacy is presented, coupled with an exhaustive evaluation of their properties, including biocompatibility, oxygen permeability, and mechanical robustness. This synthesis of contemporary research endeavors to furnish guidance for the future advancement of safer, more efficacious contact lens materials, thereby enhancing user experience and safeguarding ocular health.
