Overview - EN ISO 14889:2025 (Ophthalmic optics)

EN ISO 14889:2025, titled Ophthalmic optics - Spectacle lenses - Fundamental requirements for uncut finished lenses, defines the core requirements for uncut finished spectacle lenses (non-protective). Published by CEN as the European adoption of ISO 14889:2025, this standard replaces earlier editions (2013 / A1:2017) and takes precedence over corresponding requirements in other standards where differences exist. It is intended to support conformity with regulatory frameworks (for example EU Medical Device Regulation (EU) 2017/745) for corrective spectacle lenses.

Key topics and requirements

The standard establishes fundamental provisions across design, materials and performance for uncut finished spectacle lenses. Major technical topics include:

• Scope and applicability
  • Applies to uncut finished spectacle lenses; not applicable to protective spectacle lenses intended primarily for personal eye protection.
• Performance and design
  • Requirements for optical performance and design features relevant to single-vision, multifocal and power-variation lenses.
• Materials
  • Physiological compatibility (biocompatibility aspects relevant to lens materials).
  • Resistance to ignition / flammability of lens materials.
• Mechanical strength
  • Fundamental mechanical strength expectations for uncut lenses and resistance to mechanical damage during edging and fitting.
• Transmittance
  • General transmittance requirements for visible light and filter properties where applicable.
• Marking and identification
  • Requirements for permanent or non-permanent marking to support traceability and regulatory conformity.
• Normative references
  • Cross-references to related ISO standards such as ISO 8980‑1, ISO 8980‑2, ISO 8980‑3, ISO 8980‑4 and ISO 13666 (vocabulary).

Note: EN ISO 14889:2025 includes an Annex ZA describing relationships with EU regulations (MDR 2017/745) and indicates which clauses confer presumption of conformity for specific General Safety and Performance Requirements.

Practical applications and who uses it

This standard is essential for:

• Spectacle lens manufacturers - to define product specifications, material selection and fundamental safety/performance criteria.
• Optical laboratories and lens processors - to ensure uncut lenses meet mechanical and optical requirements prior to edging and fitting.
• Regulatory and quality teams - to demonstrate conformity with EU MDR requirements and support technical documentation and risk management.
• Test laboratories and certification bodies - to apply referenced test methods and assess compliance.
• Purchasers and specifiers (opticians, distributors) - to set procurement requirements and verify supplier compliance.

EN ISO 14889:2025 is practical for quality control, product development, regulatory compliance and supplier assessment within the ophthalmic optics supply chain.

Related standards

• ISO/EN 8980 series (Parts 1–4) - detailed specifications and test methods for uncut finished spectacle lenses
• ISO 13666 / EN ISO 13666 - ophthalmic vocabulary
• EU Regulations: MDR (EU) 2017/745 and, for dual-use protective lenses, PPE Regulation (EU) 2016/425 (see Annex ZA guidance)

Keywords: EN ISO 14889:2025, spectacle lenses, uncut finished lenses, ophthalmic optics, transmittance, mechanical strength, physiological compatibility, flammability, EU MDR.

Annex ZA
(informative)
Relationship between this European standard and the General Safety and
Performance Requirements of Regulation (EU) 2017/745 aimed to be
covered
This European standard has been prepared under M/575 to provide one voluntary means of
conforming to the General Safety and Performance Requirements of Regulation (EU) 2017/745 of 5
April 2017 concerning medical devices [OJ L 117] and to system or process requirements including
those relating to quality management systems, risk management, post-market surveillance systems,
clinical investigations, clinical evaluation or post-market clinical follow-up.
Once this standard is cited in the Official Journal of the European Union under that Regulation,
compliance with the normative clauses of this standard given in Table ZA.1 confers, within the limits of
the scope of this standard, a presumption of conformity with the corresponding General Safety and
Performance Requirements of that Regulation, and associated EFTA Regulations.
Where a definition in this standard differs from a definition of the same term set out in Regulation (EU)
2017/745, the differences shall be indicated in this Annex Z. For the purpose of using this standard in
support of the requirements set out in Regulation (EU) 2017/745, the definitions set out in this
Regulation prevail.
Where the European standard is an adoption of an International Standard, the scope of this standard
can differ from the scope of the European Regulation that it supports. As the scope of the applicable
regulatory requirements differ from nation to nation and region to region, the standard can only
support European regulatory requirements to the extent of the scope of the European regulation for
medical devices (EU) 2017/745).
NOTE 1 Where a reference from a clause of this standard to the risk management process is made, the risk
management process needs to be in compliance with Regulation (EU) 2017/745. This means that risks have to be
‘reduced as far as possible’, ‘reduced to the lowest possible level’, ‘reduced as far as possible and appropriate’,
‘removed or reduced as far as possible’, ‘eliminated or reduced as far as possible’, ’removed or minimized as far as
possible’, or ‘minimized’, according to the wording of the corresponding General Safety and Performance
Requirement.
NOTE 2 The manufacturer’s policy for determining acceptable risk must be in compliance with General Safety
and Performance Requirements 1, 2, 3, 4, 5, 8, 9, 10, 11, 14, 16, 17, 18, 19, 20, 21 and 22 of the Regulation.
NOTE 3 When a General Safety and Performance Requirement does not appear in Table ZA.1, it means that it is
not addressed by this European Standard.
Table ZA.1 — Correspondence between this European standard and Annex I of Regulation (EU)
2017/745 [OJ L 117] and to system or process requirements including those relating to quality

This definition is

This definition was
condensed to match

For devices intended by the manufacturer to be for dual use in accordance with Chapter I, Article I,
item 3 of Regulation (EU) 2017/745 the following Table ZA.4 details the relevant essential
requirements of Regulation (EU) 2016/425 on Personal Protective Equipment and their corresponding
clauses of this European Standard. Table ZA.4 however, does not imply any citation in the OJEU under
the PPE Regulation and thus does not provide presumption of conformity for the PPE Regulation.
