How Contact Lenses Reshape thee Ocular Microbiome

Contact lenses are nott inert; they y interact with the ocular environment on multiple levels. The most signitant changes occur in microbial composition, biofilm formation, and imty activation. Studies comparing lens wearrers to non-wearrs confidently show shifts in the relative divatiance of key bacterial groups, with consumpencements for infection risk.
