Overview
ISO 14889:2013/Amd 1:2017 is an amendment to the international standard concerning ophthalmic optics-specifically spectacle lenses. This document outlines fundamental requirements for uncut finished lenses, ensuring consistency and quality in the manufacturing and testing processes of lenses before they are edged or mounted. Published by the International Organization for Standardization (ISO), this amendment refines certain normative references and testing methods to enhance clarity and compliance.
Key Topics
- Scope and Purpose: The amendment focuses on uncut finished spectacle lenses, providing updated guidance regarding compliance with relevant sections of ISO 8980, which addresses optical properties and testing of spectacle lenses.
- Removal of ISO 21987 Reference: The document deletes the normative reference to ISO 21987-previously related to mounted spectacle lenses-clarifying that uncut finished lenses must now comply only with ISO 8980 requirements.
- Measurement Method Updates:
- Clarifies terminology on power measurement methods, substituting the former “front surface method” with the “segment side method” for addition power measurements.
- Updates descriptions for measurement procedures to specify the side on which power variation is present.
- Technical Committee: Prepared by ISO/TC 172 (Optics and photonics), Subcommittee SC 7 (Ophthalmic optics and instruments), ensuring that technical expertise guides these standardized requirements.
- Patent and Copyright Notes: Emphasizes that while the document is copyright protected, any patent rights related to its content are noted during development, and trade names are non-endorsing clarifications.
Applications
- Spectacle Lens Manufacturing: Lens manufacturers use ISO 14889:2013/Amd 1:2017 to confirm that uncut finished lenses meet stringent standards before edging and fitting into frames.
- Optical Quality Assurance: Laboratories performing optical testing rely on this standard for consistent and accurate addition power measurement methodologies.
- Product Compliance and Certification: Ensures that spectacle lenses comply with international ophthalmic optics standards, aiding in regulatory approval and facilitating global trade.
- Design and Development: Lens designers use the fundamental requirements as benchmarks to develop lenses with reliable optical quality and performance.
- Professional Training: Optical professionals and technicians refer to these standardized requirements in education and practical training for proper handling and evaluation of spectacle lenses.
Related Standards
