Overview
EN ISO 11380:1996 specifies the characteristics and dimensional requirements for formers used in the lens edging process of ophthalmic optics, particularly for the manufacture of spectacle lenses. These formers are essential components used in edging machines to shape lenses for seamless insertion into spectacle frames. The standard ensures consistency in the size, shape, and marking of formers, which contributes significantly to the precision and quality of finished eyewear products. This standard, approved by CEN and aligned with ISO 11380:1994, is a critical reference for manufacturers and professionals involved in optical segment fabrication and lens fitting.
Key Topics
Applications
-
Spectacle Lens Production
This standard is vital for eyewear laboratories and manufacturers using edging machines for mass production or custom lens shaping, guaranteeing interoperability with spectacle frames and reliable fit.
-
Quality Assurance in Ophthalmic Optics
Application of EN ISO 11380:1996 supports high-precision edging processes, reducing rejects due to misfitting lenses and supporting the traceability of the manufacturing process through standardized markings.
-
Product Development
Ensures that newly designed spectacle frame and lens products remain compatible with industry-standard formers, facilitating easier scalability and product interchangeability.
-
International Trade and Compliance
Adoption of internationally recognized requirements helps companies demonstrate conformity for market access and supports mutual recognition across regions.
