Full title and description

AS/NZS ISO 8980.1:2011 — Ophthalmic optics — Uncut finished spectacle lenses — Part 1: Specifications for single-vision and multifocal lenses. This joint Australian/New Zealand adoption of ISO 8980-1:2004 specifies optical and geometrical requirements and verification methods for uncut finished single‑vision and multifocal spectacle lenses.

Abstract

This standard defines the specification limits and measurement/verification methods for key optical parameters (power, cylinder axis, addition power, prismatic power and prism base setting) and geometrical characteristics (size, thickness, multifocal segment dimensions, orientation for polarizing lenses) of uncut finished spectacle lenses. It was an adoption of ISO 8980-1:2004 for use in Australia and New Zealand.

Scope

Specifies requirements and verification methods for the optical and geometrical properties of uncut finished single‑vision and multifocal spectacle lenses. The standard covers classification, reference temperature, optical tolerances (back vertex power, cylinder axis, addition power for multifocals), prismatic power and base setting, size and thickness limits, segment dimensions for multifocals and orientation requirements (e.g., for polarizing lenses), plus the methods used to verify those requirements.

Key topics and requirements

• Reference temperature for measurement and verification.
• Optical requirements: back vertex power tolerances, cylinder axis tolerances, addition power specifications for multifocals.
• Prismatic power limits and prism base setting tolerances.
• Geometrical requirements: minimum/maximum lens size and thickness criteria.
• Requirements on segment dimensions and positions for multifocal lenses.
• Orientation and marking requirements for polarizing and specialty lenses.
• Specified verification and test methods for measuring the above characteristics (focimeters, optical benches, dimensional checks).

Typical use and users

Used by spectacle lens manufacturers, surfacing and finishing laboratories, optical wholesalers and retailers, quality and compliance personnel, test laboratories, optometrists involved in product specification, and regulatory or procurement bodies that reference national standards for ophthalmic optics.

FAQ

Q: What is this standard?

A: AS/NZS ISO 8980.1:2011 is the Australian/New Zealand adoption of ISO 8980-1:2004 that sets specifications and test methods for the optical and geometrical properties of uncut finished single‑vision and multifocal spectacle lenses.

Q: What does it cover?

A: It covers classification, measurement reference conditions, optical tolerances (power, cylinder axis, addition), prismatic power and base setting, geometrical size and thickness limits, multifocal segment dimensions, orientation for polarizing lenses, and the verification methods to confirm compliance.

Q: Who typically uses it?

A: Lens manufacturers, finishing labs, quality/control technicians, testing laboratories, optical product specifiers, optometrists involved in procurement/specification, and standards/regulatory bodies.

Q: Is it current or superseded?

A: Superseded. AS/NZS ISO 8980.1:2011 has been superseded by AS/NZS 8980.1:2019 (the 2019 edition adopts ISO 8980-1:2017 with national modifications). Users should reference the 2019 edition or the current ISO edition for up-to-date requirements.

Q: Is it part of a series?

A: Yes. It is Part 1 of the ISO/AS‑NZS 8980 series addressing uncut finished spectacle lenses. The broader series and related ophthalmic optics standards cover coatings, mounted lenses, terminology and fundamental requirements.

Q: What are the key keywords?

A: Key keywords include ophthalmic optics, uncut finished spectacle lenses, single‑vision, multifocal, lens power, prismatic power, segment dimensions, verification methods, AS/NZS, ISO 8980.
