Overview

This standard specifies fundamental requirements for uncut finished spectacle lenses. It is not applicable to protective spectacle lenses. The standard concretises the relevant requirements set out in EU Directive 93/42/EEC on medical devices. Compared with the previously valid version, the transmittance specifications have been revised; reference is now made to the modified new version of DIN EN 8980-3 [see 4.5]. This implies: - modification of symbols for designation of transmittance of photochromic spectacle lenses; - specification of designations for degrees of lens tint and of tolerances for tinted spectacle lenses; - partial modification of the acceptable transmittance related with the categories for spectral transmittance; - modification of the requirements for spectacle lenses for drivers with colour perception problems; partial modification of the requirements for polarizing spectacle lenses. Furthermore, the criterion for the assessment of lens fracture has been modified [see 4.4, item a)]. The standard has been prepared by ISO/TC 172/SC 7 "Ophthalmic optics and instruments" in collaboration with CEN/TC 170 "Ophthalmic optics" (both secretariats: DIN, Germany). At DIN the responsible Working Committee is NA 027-01-08 AA "Augenoptik" ("Ophthalmic optics"), Working Group "Brillengläser" ("Spectacle lenses") at NAFuO.
