Full title and description

Ophthalmic optics — Semi-finished spectacle lens blanks — Part 1: Specifications for single-vision and multifocal lens blanks (ISO 10322-1:2016). This part of ISO 10322 defines optical and geometrical requirements, tolerances and identification/marking for semi-finished single‑vision and multifocal spectacle lens blanks intended for further processing into finished spectacle lenses.

Abstract

ISO 10322-1:2016 (fourth edition) sets classification, test methods and numerical tolerances for surface power, uniformity, cylindrical power, addition power (multifocals), and geometrical parameters (size, thickness, segment position) of semi‑finished single‑vision and multifocal lens blanks. It also specifies inspection, marking and package identification requirements, plus informative and normative annexes describing measurement and conversion procedures.

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. It applies to manufacturers, suppliers and test laboratories involved in supplying or verifying lens blanks that will be surfaced or finished for spectacle use. The standard sets the reference conditions and reference wavelengths used for tolerance statements.

Key topics and requirements

• Classification of semi‑finished blanks (single‑vision, multifocal; progressive/degressive handled in Part 2 of the series).
• Tolerances on surface power (expressed in dioptres at specified refractive indices) and uniformity limits within a defined zone around the reference point.
• Tolerances on intended surface cylindrical power and on addition (multifocal) power, with specified measurement procedures.
• Geometrical tolerances: nominal size, thickness, and multifocal segment dimensions/position tolerances.
• Test methods and measurement procedures (determination of surface power, addition-power measurement including a normative annex for transmission method, segment measurement, and surface/material inspection).
• Marking and package identification requirements and information to be made available by the manufacturer.

Typical use and users

Primary users are spectacle‑lens manufacturers, semi‑finished lens blank producers, quality and metrology laboratories, optical instrument manufacturers (focimeters/factory equipment), and purchasing/quality teams in optical supply chains. Eye‑care laboratories and some regulatory/standards bodies reference the standard for acceptance testing and supplier specifications.

Related standards

ISO 10322 is a multi‑part series. The most directly related part is ISO 10322-2:2016 (Specifications for progressive‑power and degressive‑power lens blanks). Earlier editions (for example ISO 10322-1:2006) were superseded by the 2016 edition. Ongoing work to revise/ consolidate the series has been recorded in ISO project listings (users should check the ISO catalogue for the current revision status).

FAQ

Q: What is this standard?

A: ISO 10322-1:2016 is the international standard specifying optical and geometrical specifications, tolerances and test/marking requirements for semi‑finished single‑vision and multifocal spectacle lens blanks.

Q: What does it cover?

A: It covers classification, numerical tolerances for surface power, uniformity and cylindrical/addition powers, geometrical tolerances (size, thickness, segment placement), required test methods and marking/identification information. Annexes provide measurement and conversion guidance.

Q: Who typically uses it?

A: Lens blank manufacturers and suppliers, optical laboratories and quality/inspection teams, spectacle lens manufacturers who receive blanks for surfacing, and equipment providers supplying measurement/test instruments.

Q: Is it current or superseded?

A: ISO 10322-1:2016 superseded earlier editions (for example the 2006 edition). ISO standards are reviewed periodically; work items and draft revisions for the ISO 10322 series have appeared in ISO project listings, so users should confirm the live status in the ISO catalogue if they require the absolute latest revision information.

Q: Is it part of a series?

A: Yes — ISO 10322 is a series covering semi‑finished spectacle lens blanks. Part 1 covers single‑vision and multifocal blanks; Part 2 covers progressive‑power and degressive‑power blanks (ISO 10322-2:2016). Additional related project activity has been recorded for consolidated/revised work on the series.

Q: What are the key keywords?

A: semi‑finished lens blanks; spectacle lenses; optical tolerances; surface power; addition power; multifocal; focimeter; geometric tolerances; marking; ophthalmic optics.
