Ophthalmic optics. Spectacle lenses. Parameters affecting lens power measurement Ingestion-build-65808 users and manufacturers of electrical1 Scope The purpose of this Technical Report is to explain the changes relating to power measurements in the revised editions of ISO 8980 1[6] and ISO 8980 2[7]. In order to illustrate the issues raised, an inter laboratory power measurement study was conducted on ten different lenses measured by nine organizations worldwide. Twenty five focimeters of different types were used. The test lenses were spherically powered allyl diglycol carbonate (ADC)1)
