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.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.
The main task of technical committees is to prepare International Standards. Draft International Standards
adopted by the technical committees are circulated to the member bodies for voting. Publication as an
International Standard requires approval by at least 75 % of the member bodies casting a vote.
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.
ISO 10322-1 was prepared by Technical Committee ISO/TC 172, Optics and photonics, Subcommittee SC 7,
Ophthalmic optics and instruments.
This third edition cancels and replaces the second edition (ISO 10322-1:1996), 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 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 semi-finished
single-vision and multifocal spectacle lens blanks.
NOTE The requirements for semi-finished progressive power lens blanks are given in ISO 10322-2.
2 Normative references
The following referenced documents are indispensable for the application of this document. 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, Optics and optical instruments — Focimeters
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 and the following apply.
3.1
focal-point-on-axis focimeter
FOA focimeter
focimeter in which the focal point of the beam remains on the axis of the focimeter when the lens under test is
measured at a point on the lens where prism is not zero
See Figure 1.
NOTE Examples of this design include all manual focusing focimeters and some automatic focimeters.
3.2
infinite-on-axis focimeter
IOA focimeter
focimeter in which the collimated beam coincides with the focimeter axis and the focal point of the beam goes
off the axis of the focimeter when the lens under test is measured at a point of the lens where prism is not
zero
See Figure 2.
NOTE Some automatic focimeters use this design.

4 Classification
Semi-finished lens blanks are classified as follows:
a) single-vision semi-finished lens blanks;
b) multifocal semi-finished lens blanks;
c) progressive power semi-finished lens blanks.
5 Requirements
The tolerances shall apply at a temperature of 23 °C ± 5 °C.
5.1 Optical requirements for the finished surface
5.1.1 General
The optical tolerances shall apply to the manufacturer’s stated values at the reference points of the
semi-finished lens blank at one of the reference wavelengths specified in ISO 7944.

In the case of an aspheric lens blank, the distance reference point shall be specified by the manufacturer. If no
distance reference point is identified, the blank geometric centre may be assumed to be the distance
reference point.
5.1.2 Tolerances on the surface power of semi-finished single-vision and multifocal blanks
The tolerances on the surface power as specified in Table 1 shall apply at the design reference point and shall
be measured using the method described in 6.1.
