GB/T 45706-2025 "Ophthalmic Lenses - Test Methods for Refractive Index" specifies the test methods for determining the refractive index of uncut finished ophthalmic lenses. This standard aims to ensure the accuracy and consistency in measuring key optical parameters of lenses, serving as an important basis for quality control in the eyewear industry. Typical testing instruments mentioned in the standard include optical measurement devices such as precision refractometers (e.g., V-block refractometers) and Abbe refractometers.
