Quality assurance

These materials are in conformity with the standard ISO 10993-1 defining the biocompatibility of materials.
SwissLens manufacturing process warrants this biocompatibility even after the manufacturing process, in particular without adding polish material. This standard is required by the quality assurance system of SwissLens
