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
ISO 9801:2009 - "Ophthalmic instruments - Trial case lenses" specifies requirements and test methods for mounted ophthalmic trial case lenses (full- and reduced-aperture) used in the determination of the refractive error of the eye. The standard covers optical tolerances, mechanical construction, material and surface quality, functional marking and the information that must accompany a trial lens set. Where differences exist, ISO 9801:2009 takes priority over .
