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. 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
on the ISO list of patent declarations received. www.iso.org/patents
Any trade name used in this document is information given for the convenience of users and does not
constitute an endorsement.
The committee responsible for this document is ISO/TC 172, Optics and photonics, Subcommittee SC 7,
Ophthalmic optics and instruments.
This third edition cancels and replaces the second edition (ISO 8980-3:2003), which has been technically
revised. In particular, the requirement in 6.3.2 for lenses intended for road use and driving has been
amended with an extension of three years for the continued manufacture of existing products.
ISO 8980 consists of the following parts, under the general title Ophthalmic optics — Uncut finished
spectacle lenses:
— Part 1: Specifications for single-vision and multifocal lenses
— Part 2: Specifications for progressive power lenses
— Part 3: Transmittance specifications and test methods
— Part 4: Specifications and test methods for anti-reflective coatings
— Part 5: Minimum requirements for spectacle lens surfaces claimed to be abrasion-resistant
