Caption

The challenge for near-eye display optics is to project the image on a display that is placed near the eye to a comfortable viewing distance to avoid visual fatigue and discomfort. By collimating light from the display into the pupil of the eye, the wearer perceives the projected image to be located at infinity despite the screen being physically located much closer to the eye. In order to achieve a realistic and immersive experience, exceptional optical performance over a wide field of view is required. In this work, the eyepiece optics are composed of two layers of meta-optics. As illustrated in the inset, the meta-optics consist of arrays of nanoscale pillars or meta-atoms.
