ISO TS 19979

Description / Abstract: This Technical Specification provides guidance to contact lens manufacturers for the development of information to be provided to eye care practitioners for the hygienic management of trial soft and rigid gas-permeable (RGP) contact lenses intended for multipatient use.

This Technical Specification does not address

— national regulations for labelling of contact lenses; and

— the inactivation of prions since there are no reported cases of transmission of prions by contact lenses.

Legal requirements involving national practices or regulations take precedence over this Technical Specification.
