P‐23: Image Adaptation to Human Vision (Eyeglasses Free): Full Visual‐Corrected Function in Light‐Field Near‐to‐Eye Displays

Abstract

Many design factors are highly demanded in developing optimum near‐to‐eye display, such as higher resolution and wider FOV for vivid image quality, embedded vision correction for visual comfort, and light, compact and large eye box size for wearing comfort and stylish. Several optical approaches could achieve the visual correction, such as time‐multiplexed light field, space‐multiplexed light field, holographic display, multi‐focal planes, etc. In this study, based on the space‐multiplexed light field, the authors propose a special method that can adapt the variable pupil distance and deliver several virtual image planes at the same time by an algorithm of image processing. LFNEDs utilize this method which can adapt to the diversified facial shape and avoid wearing prescription glasses in using AR/VR glasses, no matter users have myopia, hyperopia, and astigmatism.

“…In order to further simplify computation complexity in LFVR, a ray tracing-based graphic process "corrected eye box mapping" for full visual-corrected function is also included, correction for myopia, hyperopia, and even astigmatism are completed as reported perilously. 18 In order to obtain comprehensive visual-corrected function, spherical power (SPH), cylinder power (CYL), and cylinder axis (AXIS) should all be considered. As shown in Fig.…”
