Overview

EN ISO 8980-3:2022/FprA1 is the Amendment 1 to the international standard for ophthalmic optics, specifically for uncut finished spectacle lenses. This part of the ISO 8980 series provides updated transmittance specifications and precise test methods, focusing on lenses before mounting and edge-finishing. Developed by CEN and ISO, the amendment introduces enhanced requirements for evaluating the light transmittance properties of lenses, especially concerning wavelength cut claims, and outlines improved procedures for measurement accuracy.

The updated document is critical for stakeholders in ophthalmic equipment manufacturing, quality assurance, and regulatory compliance, as it ensures that finished lenses meet both industrial and safety requirements regarding their optical properties.

Key Topics

• Transmittance Specifications: The standard sets requirements for how much light and specific wavelengths can pass through uncut spectacle lenses, including updated claims around solar radiation attenuation.
• Wavelength Cut Claims: New provisions specify procedures and thresholds for lenses that claim to block certain wavelengths, detailing rigorous criteria for spectral transmittance.
• Enhanced Test Methods: Amendments provide clearer guidelines on the use of spectrophotometers and the determination of measurement uncertainties, ensuring precision and repeatability in testing.
• Measurement Uncertainty: Updated thresholds for acceptable uncertainty in spectral transmittance ensure accurate verification of lens claims, supporting reliable compliance checks.
• Parameters Influencing Measurements: The standard discusses factors such as lens thickness and geometry, as well as instrument characteristics that can impact the measurement of wavelength cut.

Applications

EN ISO 8980-3:2022/FprA1 has broad practical value across the ophthalmic lens industry:

• Manufacturing Quality Control: Manufacturers use these specifications and test methods to validate lens batches, ensuring each product complies with international transmittance standards before being sold or further processed.
• Regulatory Compliance: Lenses tested according to this amendment are more likely to be accepted in international markets, simplifying the process of meeting regional or national regulatory requirements.
• Product Development: Engineering teams rely on this standard to design new lenses that meet or exceed safety thresholds for UV and visible light transmission, supporting innovation in protective and medical eyewear.
• Consumer Safety: By standardizing and verifying wavelength cut claims, the document helps ensure that spectacle lenses effectively protect users from harmful UV rays and intense solar radiation.

Related Standards

Organizations working with ophthalmic optics and spectacle lenses should also consider the following standards:

• EN ISO 8980-1 and 8980-2: Cover other aspects of uncut finished spectacle lenses, including optical and physical requirements.
• EN ISO 18526-2:2020: Provides guidance on measurement uncertainty for lens testing equipment, specifically cited for in-depth advice on uncertainty evaluation.
• ISO/IEC Guide 98-3: International guide for the expression of measurement uncertainty, referenced for evaluating and expressing confidence in test results.
• ISO 8980 Series: Comprehensive standards for spectacle lenses, supporting harmonized best practices in ophthalmic optics.

For stakeholders in ophthalmic optics, following EN ISO 8980-3:2022/FprA1 and related standards ensures product quality, regulatory alignment, and user safety, supporting a trusted and robust global eyewear industry.
