Ophthalmic optics - Uncut finished spectacle lenses - Part 3 : transmittance specifications and test methods

This document specifies requirements for the transmittance properties of uncut and unmounted finished spectacle lenses, including attenuation of solar radiation. This document is not applicable to —    spectacle lenses having specific transmittance or absorption characteristics prescribed for medical reasons, —    products to which specific personal protective equipment transmittance standards apply, and —    products intended for direct observation of the sun, such as for solar-eclipse viewing. NOTE 1    By reference to ISO 21987 and ISO 14889, this document also applies to lenses mounted in spectacles. NOTE 2    Optical and geometric requirements are given for uncut finished spectacle lenses in ISO 8980‑1 and ISO 8980‑2, and for mounted lenses, in ISO 21987.
