  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.
