Prescription AR: A Fully-Customized Prescription-Embedded Augmented Reality Display (1907.04353v1)

Abstract: In this paper, we present a fully-customized AR display design that considers the user's prescription, interpupillary distance, and taste of fashion. A free-form image combiner embedded inside the prescription lens provides augmented images onto the vision-corrected real world. We establish a prescription-embedded AR display optical design method as well as the customization method for individual users. Our design can cover myopia, hyperopia, astigmatism, and presbyopia, and allows the eye-contact interaction with privacy protection. A 169$g$ dynamic prototype showed a 40$^\circ$ $\times$ 20 $^\circ$ virtual image with a 23 cpd resolution at center field and 6 mm $\times$ 4 mm eye box, with the vision-correction and varifocal (0.5-3$m$) capability.
