Апстракт

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.
