Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards
bodies (ISO member bodies). The work of preparing International Standards is normally carried out
through ISO technical committees. Each member body interested in a subject for which a technical
committee has been established has the right to be represented on that committee. International
organizations, governmental and non-governmental, in liaison with ISO, also take part in the work.
ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of
electrotechnical standardization.
The procedures used to develop this document and those intended for its further maintenance are
described in the ISO/IEC Directives, Part 1. In particular the different approval criteria needed for the
different types of ISO documents should be noted. This document was drafted in accordance with the
editorial rules of the ISO/IEC Directives, Part 2 (see www.iso.org/directives).
Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights. ISO shall not be held responsible for identifying any or all such patent rights. Details of
any patent rights identified during the development of the document will be in the Introduction and/or

Introduction
Contact lens care products (CLCP) are used with contact lenses. These products rinse, clean, disinfect,
store, wet, aid the comfort of, and condition contact lenses. Some products have one function, while
others are multifunctional.
Usually, products manufactured for use with hydrogel lenses may be used with rigid gas-permeable
(RGP) or poly (methyl methacrylate) (PMMA) lenses, but products specifically used for RGP or PMMA
contact lenses are not usually suitable for hydrogel lenses.
Most CLCPs are manufactured as solutions and are commonly packaged and sold in multidose containers.
Dry products are sold as tablets or granules and shall be dissolved in a suitable solvent immediately
prior to use.
If the contact lens care product solution does not have any antimicrobial activity itself, an antimicrobial
preservative can be added to the product to inhibit the growth of microorganisms that might be
introduced from repeated dispensing during use and subsequent storage. All antimicrobial agents
have the potential for toxicity to the user. For maximum protection to the user, the concentration of the
preservative should be such that it provides adequate preservative activity with minimum toxicity.
There are differences between ophthalmic preparations and contact lens care products and some
of these differences are significant in relation to preservative efficacy testing. Typically, ophthalmic
preparations are packaged in small-volume containers and are used for short periods on compromised
eyes. Contact lens care products are distributed in larger volume containers and are used with contact
lenses on a long term basis on healt
