 A silver-impregnated lens case has been developed which helps to eradicate any potentially contaminating microbes that come in contact with the lens case.Additionally, a number of antimicrobial agents are being developed that have been embedded into contact lenses themselves.Lenses with covalently attached selenium molecules have been shown to reduce bacterial colonization without adversely affecting the cornea of a rabbit eye and octyl glucoside used as a lens surfactant significantly decreases bacterial adhesion.
