Overview

ISO 8980-4:2026 is an international standard developed by ISO for the ophthalmic optics industry. This standard specifies the optical and non-optical requirements, as well as the test methods, for the anti-reflective and hydrophobic coatings applied to uncut finished spectacle lenses. The document focuses on the performance properties of these coatings-such as reflectance, water repellency, and durability-to ensure that spectacle lenses meet quality and usability expectations.

This document is part of the ISO 8980 series, which addresses various aspects of finished spectacle lenses. ISO 8980-4:2026 is particularly important for lens manufacturers, optical labs, and quality assurance professionals involved in the production, testing, and certification of spectacle lenses with specialized surface coatings.

Key Topics

Scope and Purpose

Establishes the criteria for anti-reflective and hydrophobic coatings on spectacle lenses
Excludes topics covered by other standards in the ISO 8980 series and evaluation of color of reflected light

Optical Requirements

Specifies maximum permissible luminous and mean reflectance values for anti-reflective coatings
Sets criteria for minimum usable diameter of coated areas

Non-optical Requirements

Defines criteria for the water-repellent (hydrophobic) behavior based on contact angle measurements

Testing and Evaluation Methods

Describes procedures for measuring spectral, luminous, and mean reflectance
Outlines methods for assessing static contact angle to confirm hydrophobicity
Provides durability testing under environmental cycling and controlled abrasion

Reporting

Guidance on the information to be provided by manufacturers regarding coating properties
Reference requirements for product documentation claiming compliance

Applications

ISO 8980-4:2026 has direct practical applications in the ophthalmic optics industry:

Quality Control and Assurance

Ensures consistency in anti-reflective performance and water repellency for spectacle lenses, aiding in customer satisfaction and compliance

Product Development

Facilitates research, design, and improvement of lens coatings to meet international market requirements

Supplier and Manufacturer Communication

Provides a common framework for specifying and verifying lens coating properties, streamlining procurement and product validation

Testing Laboratories

Standardizes testing procedures for evaluating anti-reflective and hydrophobic coatings, enabling reliable, reproducible results

Regulatory Compliance

Supports compliance with essential safety and performance criteria for spectacle lenses, as required by global and regional authorities

Related Standards

The following standards are closely related and referenced within ISO 8980-4:2026:

ISO 8980-1: Specifications for single-vision and multifocal uncut finished spectacle lenses

ISO 8980-2: Specifications for power-variation lenses

ISO 8980-3: Specifications and test methods for transmittance

ISO 13666: Definitions and vocabulary for spectacle lenses

ISO 14889: Fundamental requirements for uncut finished spectacle lenses

ISO 48-2: Determination of hardness for rubber, relevant to abrasion tools used in durability testing

Adherence to ISO 8980-4:2026, together with its related standards, helps ensure spectacle lenses offer the required optical clarity, ease of cleaning, durability, and user comfort, supporting both consumer confidence and industry best practices.
