Abstract
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 , is a critical reference for manufacturers and professionals involved in optical segment fabrication and lens fitting.
