<p>The present invention relates to an antimicrobial contact lens case and an ophthalmic solution container that are comprised of an antimicrobial polymeric resin and have antimicrobial surfaces, but which do not contaminate the lens or solution with antimicrobial agent. The present invention provides a novel antimicrobial contact lens container which is adapted to hold one or more contact lenses and ophthalmic solution. The contact lens container is made from a polymeric material containing zeolite which has ion-exchanged thereon silver ions in an amount from about 0.1 to 5 wt.% of the zeolite and ammonium ions in an amount from about 0.5 to 15 wt.% of the zeolite. The zeolite is present in an amount from about 0.5 to 5 wt. % of the polymeric material. The contact lens container of the invention does not leach ions from the polymeric material into the ophthalmic solution in a substantially antimicrobial amount.</p> |
