# Prescription AR: A Fully-Customized Prescription-Embedded Augmented Reality Display

## TL;DR

This paper introduces a fully-customized augmented reality display integrated into prescription lenses, enabling personalized vision correction, eye-contact interaction, and varifocal AR experiences in a lightweight design.

## Contribution

It presents a novel prescription-embedded AR display design and customization method that supports various vision impairments and enhances user interaction and privacy.

## Key findings

- Achieved a 40°×20° virtual image with 23 cpd resolution.
- Developed a lightweight 169g prototype with vision correction and varifocal capabilities.
- Demonstrated effective customization for individual users' prescriptions.

## 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.
