IEC 63145-20-20:2019 (E) specifies the standard measurement conditions and measurement methods for determining the image quality of eyewear displays. This document is applicable to non-see-through type (virtual reality \u00c3\u00a2??VR\u00c3\u00a2?? goggle) and see-through type (augmented reality \u00c3\u00a2??AR\u00c3\u00a2?? 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
