ISO 19979:2018为制造商提供了指导，为眼部护理从业者提供多患者使用的水凝胶、复合和刚性透气（RGP）隐形眼镜的卫生管理信息。 ISO 19979:2018不适用于: -隐形眼镜的标签； -朊病毒和病毒的灭活，因为隐形眼镜没有标准化的方法。 ISO 19979:2018可作为制定多患者使用卫生管理程序的指南。 注:ISO 14729不包括多患者使用。

ISO 19979:2018 provides guidance to manufacturers for the development of information to be provided to eye care practitioners for the hygienic management of trial hydrogel, composite and rigid gas-permeable (RGP) contact lenses intended for multipatient use. ISO 19979:2018 does not apply to: - labelling of contact lenses; - the inactivation of prions and viruses since there are no standardised methods available for contact lenses. ISO 19979:2018 can be used as guidance for the development of a hygienic management procedure for multipatient use. NOTE ISO 14729 does not cover multipatient use.
