Ophthalmic optics. Contact lenses and contact lens care products. Cytotoxicity testing of contact lenses in combination with lens care solution to evaluate lens/solution interactions Ingestion-build-181247 BS EN 546-3 provides you1 Scope This International Standard describes an in vitro test method to assess the potential cytotoxic effects that may arise due to interaction of contact lenses with contact lens care solutions. NOTE The potential of a contact lens or a contact lens care solution to cause cytotoxicity by itself can be evaluated in accordance with general guidance in ISO 10993 5.
