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. The optics was optimized for each prescription level, which can reduce the mass production cost while satisfying the user's taste. The foveated optimization method was applied which distributes the pixels in accordance with human visual acuity. Our design can cover myopia, hyperopia, astigmatism, and presbyopia, and allows the eye-contact interaction with privacy protection. A 169g dynamic prototype showed a 40° × 20° virtual image with a 23 cpd resolution at center field and 6 mm × 4 mm eye-box, with the vision-correction and varifocal (0.5-3m) capability.
在本文中，我们展示了一种完全定制的增强现实（AR）显示设计，该设计考虑了用户的处方、瞳距和时尚品味。嵌入在处方镜片内的自由曲面图像合成器可在经过视力矫正的现实世界上提供增强图像。针对每个处方级别对光学器件进行了优化，这既能降低大规模生产成本，又能满足用户的品味。应用了注视点优化方法，该方法根据人类视力来分配像素。我们的设计可以涵盖近视、远视、散光和老花眼，并允许进行眼神交流互动且具备隐私保护功能。一个169克的动态原型在中心视场显示出一个40°×20°的虚拟图像，分辨率为23周/度，眼盒尺寸为6毫米×4毫米，具备视力矫正和变焦（0.5 - 3米）功能。
