Abstract
Overview
ISO 8980-2:2017 - "Ophthalmic optics - Uncut finished spectacle lenses - Part 2: Specifications for power‑variation lenses" specifies requirements and verification methods for the optical and geometrical properties of uncut finished power‑variation spectacle lenses. The standard sets measurement conditions (reference temperature 23 °C ± 5 °C), test instruments (focimeter conforming to ) and reference wavelengths () to ensure consistent quality and interchangeability of lenses used in eyeglasses.
