Title: LENS CARE PRODUCT FOR OZONE-BASED CLEANING/DISINFECTING OF CONTACT LENSES
Abstract:
The present invention provides an aqueous lens care solution for disinfecting and/or cleaning contact lenses in an ozone-based lens care system. The lens care solution of the invention is a hypotonic solution, has an osmolality at about 25C of from about 200 mOsm/kg to about 260mOsm/kg, and comprises at least one relatively-ozone-inert buffering agent selected from the group consisting of boric acid, sodium tetraborate, potassium tetraborate, acetic acid, sodium acetate, potassium acetate, and a mixture thereof. The aqueous lens care solution is compatible with ozone electrolytically generated in an ozone-based lens care system as characterized by comprising about 30 mM or less of chloride ion and less than about 10 mM of one or more ozone-interfering buffering agents.
