Fourier provides an AR solution that embeds an angular and wavelength‑selective metasurface optical combiner directly into standard ophthalmic lenses, allowing a µLED projector to deliver high‑brightness RGB images while keeping the lens fully transparent. The technology adds less than 1.5 g of weight, integrates with existing lens manufacturing processes, and can be produced for under $10 per unit, enabling OEMs and eyewear makers to add affordable smart‑glass functionality to prescription or fashion frames.

Problem
Current augmented reality eyewear relies on bulky waveguide optics that add significant weight, reduce lens transparency, and increase manufacturing complexity, limiting widespread adoption and integration with prescription lenses.
Solution
Fourier AR™ uses an angular and wavelength‑selective metasurface optical combiner that is invisibly embedded within a standard ophthalmic lens. The metasurface reflects RGB light from a µLED projector directly into the eye while remaining transparent to the external environment, enabling all‑day wear with less than 1.5 g of added weight. The technology is fabricated with high‑volume semiconductor processes and integrates into existing lens surfacing, coating, and edging workflows, allowing OEMs to produce smart glasses at under $10 per unit without compromising frame style or prescription power.
Target Audience
Fourier AR™ targets smart‑glass OEMs, eyewear manufacturers, and lens producers seeking to add AR functionality to prescription or fashion frames while maintaining low weight, high transparency, and affordable unit costs.
Features
