IEC 63145-20-10:2019(E) specifies the standard measurement conditions and measurement methods for determining the optical properties of eyewear displays. This document applies to non-see-through type (virtual reality \u201cVR\u201d goggles) and see-through type (augmented reality \u201cAR\u201d glasses) eyewear displays using virtual image optics. Contact lens-type displays and retina direct projection displays are out of the scope of this document.<\/p>\n
