ISO 10322:2026 Quang học nhãn khoa — Phôi bán thành phẩm
ISO/FDIS 10322:2026 is an international standard published by the International Organization for Standardization (ISO) under the technical committee ISO/TC 172/SC 7, focusing on ophthalmic optics. This standard specifies the optical and geometrical requirements for all semi-finished spectacle lens blanks used in the production of single-vision, multifocal, and power-variation lenses. The standard aims to unify quality criteria, provide consistent testing methods, and ensure reliable performance of semi-finished lens blanks.
Key aspects include definitions of tolerances for surface power, cylindrical power, and geometrical dimensions such as actual and usable sizes. It harmonizes classifications by the type of finished surface rather than intended use and aligns lens measurements with reference wavelengths to ensure precision.
