Overview
IEC 63145-1-2:2022 - Eyewear display, Part 1-2: Generic – Terminology is an international terminology standard that defines the vocabulary used for eyewear displays and image/video rendering in augmented reality (AR), virtual reality (VR), mixed reality (MR) and related systems. Published as Edition 1.0 (July 2022), this part of the IEC 63145 series establishes consistent, unambiguous terms for designers, engineers, test labs and standards bodies working with eyewear displays.
Key topics
The standard organizes terms and definitions into clear categories to support consistent communication across the XR ecosystem. Major topics include:
- Display types - eyewear display, head‑mounted display (HMD), contact‑lens display, optical see‑through and video see‑through, waveguide displays, monocular/binocular/bi‑ocular and single‑view devices.
- Computer‑generated visual environment - definitions for VR, AR, augmented virtuality (AV), mixed reality (MR), extended reality (XR), immersive and hyper‑reality concepts.
- Display optical system - virtual‑image optical system, field of view (FOV), eye point, eye relief, eye rotation and related optical concepts used in metrology and design.
- Optical performance & performance characteristics - terminology for optical performance metrics and system characteristics used across eyewear displays.
- Visual ergonomics - terms addressing user comfort, viewing geometry and human factors relevant to eyewear displays.
- Display electronics & image rendering - vocabulary for image sources, image displays (OLED, LCD, micro‑LED, LCOS, DLP as examples in the document) and terms related to rendering pipelines and video presentation.
Note: IEC 63145-1-2 provides definitions rather than prescriptive performance limits; it supports other parts of the series and test standards that specify requirements.
Applications
IEC 63145-1-2 is practical for:
- Creating unambiguous product specifications and design briefs for AR/VR headsets and eyewear displays.
- Aligning test procedures and reporting language in R&D and certification labs.
- Drafting technical documentation, interoperability agreements and procurement contracts.
- Supporting regulatory submissions, safety assessments and standards harmonization.
Who should use it
- Eyewear display manufacturers and optical engineers
- AR/VR/MR software and content developers
- Test laboratories and conformity assessment bodies
- Standards committees, technical writers and procurement teams
- Academics and researchers in human factors and display technology
