Full title and description

ISO 8980-1:2017 — Ophthalmic optics — Uncut finished spectacle lenses — Part 1: Specifications for single‑vision and multifocal lenses. This International Standard specifies the requirements and verification methods for the optical and geometrical properties of uncut finished single‑vision and multifocal spectacle lenses intended for prescription eyewear and mass‑produced corrective lenses.

Abstract

ISO 8980-1:2017 sets out the criteria and test procedures to confirm that uncut finished spectacle lenses meet defined optical and geometrical performance characteristics (for example dioptric power, astigmatism, prismatic effect, centration and surface quality) and defines verification methods for manufacturers, laboratories and regulators. The standard replaces earlier editions and provides harmonized tolerances and inspection requirements for single‑vision and multifocal lenses.

Scope

Applies to uncut finished single‑vision and multifocal spectacle lenses and specifies the dioptric and geometrical properties to be measured and the verification methods to be used. The scope covers optical characteristics (power and power variation, cylinder, axis, add power for multifocals), geometrical properties (centration, prismatic effect, lens thickness and edge geometry where relevant), cosmetic/surface quality inspection and associated test methods needed to determine conformity with specified tolerances. It is intended for use at production, quality control and conformity assessment stages.

Key topics and requirements

• Definitions and terminology relevant to uncut finished spectacle lenses (single‑vision and multifocal).
• Requirements for optical power (back vertex power), cylinder and axis tolerances and acceptance criteria for single‑vision and multifocal designs.
• Requirements and methods for measuring power variation and verifying add power in multifocal lenses.
• Geometrical checks including centration, prismatic effect (prismatic power) and positional tolerances.
• Surface and cosmetic quality inspection criteria to detect defects that affect optical performance or wearer safety.
• Specified measurement and verification procedures (test conditions and instruments) to ensure reproducible assessment in laboratories and production environments.
• Labelling and identification expectations to support traceability and conformity (implicit through measurement and marking requirements).

Typical use and users

Used by spectacle lens manufacturers, optical laboratories, quality managers, conformity assessment bodies, opticians and regulatory authorities to define acceptable manufacturing tolerances, perform incoming/outgoing quality control, and assess compliance. Also used by standards committees and test houses developing test methods or aligning national regulations with international practice.

Related standards

ISO 8980-1:2017 is part of the ISO 8980 series addressing uncut finished spectacle lenses. Closely related standards include ISO 8980-2:2017 (specifications for power‑variation lenses / additional parts of the series) and earlier editions of ISO 8980-1 (for example the 2004 edition). A committee draft for a subsequent revision (ISO/CD 8980-1) has been posted as work under development, indicating the series is periodically reviewed.

Q: What does it cover?

A: It covers optical parameters (power, cylinder, axis, add power for multifocals), geometrical parameters (centration, prismatic effect), surface/cosmetic inspection and the measurement methods used to verify these characteristics to ensure lenses meet defined tolerances.

Q: Who typically uses it?

A: Lens manufacturers, optical laboratories, opticians and retailers, quality and regulatory bodies, and test houses use the standard for production control, acceptance testing and conformity assessment.
