Ophthalmic instruments. Eye refractometers Ingestion-build-143074 or cylinders) that are taken1 Scope This International Standard, together with ISO 15004 1, specifies requirements and test methods for eye refractometers using an objective measuring principle. It is limited to the measurement of spherocylindrical refractive error. This International Standard takes precedence over ISO 15004 1, if differences exist.
