Full title and description

Ophthalmic optics — Semi-finished spectacle lens blanks — Part 2: Specifications for progressive-power and degressive-power lens blanks. This international standard specifies the optical and geometrical properties, test and marking requirements for semi-finished spectacle lens blanks that have finished progressive-power or degressive-power surfaces.

Abstract

ISO 10322-2:2016 sets requirements for optical performance and geometrical tolerances of semi-finished spectacle lens blanks with finished progressive-power and degressive-power surfaces, and includes measurement methods and acceptance criteria intended for manufacturers, test laboratories and conformity assessment. The 2016 revision updated measurement descriptions and extended scope to cover single-sided finished degressive-power blanks.

Scope

This part of ISO 10322 specifies requirements for the optical and geometrical properties of semi-finished spectacle lens blanks that have finished progressive-power and degressive-power surfaces. The 2016 revision broadened application to include single-sided finished degressive-power blanks and revised the descriptions of measurement methods. The standard is intended to provide uniform criteria for manufacture, inspection and acceptance of these semi-finished blanks.

Key topics and requirements

• Definitions and classification of semi-finished progressive and degressive-power lens blanks.
• Optical requirements: power distribution, progressive corridor characteristics and allowable optical deviations.
• Geometrical requirements: base curve, thickness, blank diameter, centre markings and datum locations.
• Dimensional tolerances and acceptance criteria for cutting and edging processes.
• Measurement methods and test procedures for verifying optical and geometrical properties (revised in the 2016 edition).
• Marking, identification and accompanying information required for traceability and use by lens processors.

Typical use and users

Used by spectacle lens manufacturers, semi-finished lens blank producers, optical laboratories, quality and test laboratories, regulatory bodies, and procurement/specification teams in the ophthalmic supply chain. The standard supports manufacturing controls, supplier specifications and conformity assessment procedures for lens blanks that will be surfaced and edged into finished spectacle lenses.

Related standards

ISO 10322 is a multipart series. Relevant related documents include ISO 10322‑1:2016 (specifications for single‑vision and multifocal lens blanks) and the ongoing consolidation work under ISO/FDIS 10322 (a final draft to harmonize semi-finished blanks across parts). National/adopted versions exist as EN ISO 10322-2:2016 and equivalent national publications.

FAQ

Q: What is this standard?

A: ISO 10322-2:2016 is an international standard that defines requirements and test methods for semi-finished spectacle lens blanks with finished progressive‑power and degressive‑power surfaces, used as inputs to the lens surfacing and finishing process.

Q: What does it cover?

A: It covers optical characteristics (power distribution and progressive corridor properties), geometrical features (diameter, base curve, thickness, centre/marking positions), allowable tolerances, measurement procedures and marking/identification for progressive and degressive-power blanks. The 2016 edition updated measurement descriptions and scope to include single-sided finished degressive blanks.

Q: Who typically uses it?

A: Lens blank manufacturers, spectacle lens laboratories, quality-control and test labs, standards bodies, purchasing/specification engineers and regulators in the ophthalmic optics supply chain.

Q: Is it current or superseded?

A: ISO 10322-2:2016 is the current published edition (Edition 4, 2016). ISO indicates the 2016 edition is in the review lifecycle and work to consolidate the series under ISO/FDIS 10322 has been progressed; users should check national bodies for the latest adoption status or any subsequent revisions.

Q: Is it part of a series?

A: Yes — ISO 10322 is a multipart standard for semi‑finished spectacle lens blanks. Part 1 covers single‑vision and multifocal blanks (ISO 10322‑1:2016), Part 2 covers progressive and degressive blanks (this document), and consolidation work under ISO/FDIS 10322 aims to harmonize parts.

Q: What are the key keywords?

A: ophthalmic optics; semi‑finished spectacle lens blanks; progressive-power; degressive-power; optical tolerances; geometrical tolerances; measurement methods; marking; spectacle lenses.
