IEC 63145-22-20:2020(E) specifies the standard measurement conditions and measuring methods for determining the see-through optical properties and imaging quality of augmented reality (AR) eyewear displays. This includes the transmission characteristics and ambient optical performance of the eyewear displays. Contact lens type displays are out of the scope of this document. NOTE?The relationship between the scope and other documents (IEC 63145-20-10, IEC 63145-22-10) is shown in Annex A.
