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
on the ISO list of patent declarations received (see 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.
For an explanation on the meaning of ISO specific terms and expressions related to conformity
assessment, as well as information about ISO’s adherence to the WTO principles in the Technical
Barriers to Trade (TBT) see the following URL: Foreword - Supplementary information
The committee responsible for this document is ISO/TC 172, Optics and photonics, Subcommittee SC 7,
Ophthalmic optics and instruments.
This fourth edition cancels and replaces the third edition (ISO 10322-1:2006), which has been
technically revised.
ISO 10322 consists of the following parts, under the general title Ophthalmic optics — Semi-finished
spectacle lens blanks:
— Part 1: Specifications for single-vision and multifocal lens blanks
— Part 2: Specifications for progressive-power and degressive-power lens blanks

Ophthalmic optics — Semi-finished spectacle lens
blanks —
Part 1:
Specifications for single-vision and multifocal lens blanks
1 Scope
This part of ISO 10322 specifies requirements for the optical and geometrical properties of all semi-
finished single-vision and multifocal spectacle lens blanks.
2 Normative references
The following documents, in whole or in part, are normatively referenced in this document and are
indispensable for its application. For dated references, only the edition cited applies. For undated
references, the latest edition of the referenced document (including any amendments) applies.
ISO 7944, Optics and optical instruments — Reference wavelengths
ISO 8598-1, Optics and optical instruments — Focimeters — Part 1: General purpose instruments
ISO 13666, Ophthalmic optics — Spectacle lenses — Vocabulary
3 Terms and definitions
For the purposes of this document, the terms and definitions given in ISO 13666 apply.
4 Classification
Semi-finished lens blanks (shortened to lens blanks in the remainder of this part of ISO 10322 for easier
reading) are classified according to the finished surface as follows:
a) single-vision lens blanks;
b) multifocal lens blanks;
c) progressive-power and degressive-power lens blanks.
5 Requirements
5.1 General
The tolerances shall apply at a temperature of 23 °C ± 5 °C.
5.2 Optical requirements for the finished surface
5.2.1 General
The optical tolerances shall apply to the manufacturer’s stated values at the reference points of the lens
blank at one of the reference wavelengths specified in ISO 7944.

The reference point should be specified by the manufacturer. If no reference point is specified, the
blank’s geometric centre may be assumed to be the reference point.
The optical tolerances in Tables 1, 2 and 3 are expressed as surface power values, in dioptres, in the
refractive index of the material of the lens blank being measured.
