"Critical to XR’s mass adoption is enabling users to interact with virtual images for as long as they like, without feeling nauseous, and to seamlessly shift focus between physical and virtual environments. Our technology, compatible with LCD, OLED, or any type of display, makes that possible. By projecting a digital image onto a user’s retina, keeps the image in focus regardless of how the eyes adjust to the surrounding world, completely eliminating any discomfort. After more than a decade of research, we’re now ready to take our technology to market, unleashing possibilities across automotive, medical, engineering industries, and more."
