However, Ma and his team have pioneered a solution that may change this.<\/p>\n\n\n\n<p>They  have ingeniously combined a metasurface with a refractive lens and microLED screen, creating a display small enough to fit into eyeglasses without sacrificing performance. The metasurface, an ultrathin silicon nitride film, is etched with a precision pattern that shapes and focuses light from tiny green microLEDs. This light then forms an image on a synthetic polymer refractive lens, which sharpens and refines the picture.<\/p>\n\n\n\n<p>To enhance the final image, the team utilized computer algorithms that correct minor optical imperfections before the light leaves the microLED. This preprocessing step was crucial in achieving high image quality. According to their tests, the prototype eyeglasses with the hybrid AR display showed less than 2% distortion across a 30 degree field of view, matching the image quality of current four-lens commercial AR systems.<\/p>\n\n\n\n<div style=\"height:20px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-full\"><img loading=\"lazy\" decoding=\"async\" width=\"292\" height=\"700\" src=\"https:\/\/www.tun.com\/home\/wp-content\/uploads\/2024\/09\/New-AR-Glasses.jpg\" alt=\"\" class=\"wp-image-6420\" srcset=\"https:\/\/www.tun.com\/home\/wp-content\/uploads\/2024\/09\/New-AR-Glasses.jpg 292w, https:\/\/www.tun.com\/home\/wp-content\/uploads\/2024\/09\/New-AR-Glasses-125x300.jpg 125w\" sizes=\"auto, (max-width: 292px) 100vw, 292px\" \/><\/figure>\n<\/div>\n\n\n<p class=\"has-text-align-center\">CAPTION: A new, simpler AR display incorporated into eyeglasses takes an original image (top) and produces a projected image (middle) that is further enhanced by a computer algorithm (bottom).<\/p>\n\n\n\n<p class=\"has-text-align-center\"><em>Credit:<\/em> Adapted from ACS Photonics 2024, DOI: 10.1021\/acsphotonics.4c00989<\/p>\n\n\n\n<div style=\"height:4px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<p>The results were impressive.
