Ophthalmic optics. Uncut finished spectacle lenses - Transmittance specifications and test methods Ingestion-build-53008 radiological equipment)1 Scope This part of ISO 8980 specifies requirements for the transmittance properties of uncut finished spectacle lenses and mounted pairs, including attenuation of solar radiation. This part of ISO 8980 is not applicable to spectacle lenses having particular transmittance or absorption characteristics prescribed for medical reasons; products where specific personal protective equipment transmittance standards apply; products intended for direct
