ISO 9801:2009 specifies requirements for mounted ophthalmic full and/or reduced aperture trial case lenses for the determination of the refractive error of the eye. ISO 9801:2009 takes priority over ISO 15004-1, if differences exist.
Abstract
Overview
EN ISO 9801:2009 - Ophthalmic instruments - Trial case lenses () specifies requirements and test methods for used to determine the refractive error of the eye. Adopted by CEN as EN , this standard covers full- and reduced-aperture trial lenses, their optical tolerances, mechanical construction, surface quality and marking. Where differences exist, takes priority over .
