Overview
EN ISO 10322:2026 - Ophthalmic optics - Semi-finished blanks (ISO 10322:2026) - published by CEN, establishes standardized criteria for the optical and geometrical properties of semi-finished blanks used in ophthalmic optics, specifically for the production of spectacle lenses. This international standard benefits manufacturers, laboratories, and regulatory agencies by ensuring consistency, safety, and quality in the production and supply chain of semi-finished ophthalmic blanks.
Key Topics
Applications
EN ISO 10322:2026 is highly relevant for:
- Ophthalmic Lens Manufacturers: Ensures blanks meet quality requirements before further processing or finishing, facilitating reliable downstream manufacturing of single-vision, multifocal, and progressive spectacle lenses.
- Quality Assurance Labs: Provides standardized test methods and tolerances for verifying compliance with international quality benchmarks.
- Optical Wholesalers and Distributors: Ensures proper labeling, identification, and consistent quality across product lines, enabling traceability and facilitating regulatory compliance.
- Custom and High-Precision Lens Production: Supports the use of advanced technology (such as freeform surfacing) where accurate, high-quality semi-finished blanks enable production of a wide variety of optical lens designs.
- Import/Export Compliance: Assists stakeholders in demonstrating conformity to international and European market requirements, streamlining cross-border trade.
