TL;DR
Lumus has demonstrated a prototype of waveguides capable of supporting a 70° field of view in thin AR glasses. The development confirms the company’s progress toward more immersive, usable AR eyewear by 2026, with upcoming privacy features and thinner lenses planned.
Lumus has confirmed the development of waveguides capable of supporting a 70° field of view in thin augmented reality glasses, a major milestone for the industry. During a recent private demo, Lumus showcased a prototype that achieves this wider FOV without the use of exotic materials, indicating progress toward commercially viable, immersive AR eyewear by 2026. This development is significant because it addresses a key limitation in current AR glasses, potentially transforming user experience and adoption.
The demonstration involved a prototype AR glasses using Lumus’s new waveguides, which successfully delivered a 70° field of view—more than double the typical 20° of existing products like Meta Ray-Ban. The prototype’s display quality was promising, with decent resolution, good brightness, and acceptable color fidelity, though some issues with distortion and washed-out colors remain. Lumus explained these are due to current display limitations, not the waveguides themselves, and future upgrades are expected to resolve these issues.
Importantly, the prototype lacked privacy features, allowing external viewers to see light leakage, but Lumus plans to incorporate privacy technology similar to Meta’s Ray-Ban in future versions. Additionally, Lumus showcased a new series of waveguides—series “A”—that halve the lens thickness from 1.6mm to 0.8mm, enabling thinner, lighter glasses. The company emphasized that achieving a 70° FOV with a glass-based waveguide is a breakthrough, as it was previously thought to require more exotic materials like silicon carbide.
Implications for Next-Generation AR Glasses
This development indicates that wider FOV AR glasses are becoming technically feasible with existing materials, moving closer to mass-market availability. A 70° FOV significantly enhances immersion and usability, especially for productivity applications, potentially accelerating adoption of AR in daily life and work. The reduction in lens thickness also suggests lighter, more comfortable glasses, which could improve user comfort and wearability, critical factors for widespread use.

Progress in Waveguide Technology and Industry Goals
Lumus has been a key supplier of waveguides for AR glasses, with previous prototypes supporting 30° and 50° FOVs. The company’s recent demonstration aligns with industry expectations of a 70° FOV by 2026, a target they had announced last year. The challenge has been balancing display quality, waveguide size, and privacy features. Lumus’s focus on using glass rather than exotic materials marks a shift toward more practical manufacturing, while their ongoing work on thinner lenses aims to improve comfort and aesthetics.
While current prototypes are still limited by display technology, Lumus’s progress suggests that these barriers could be overcome within the next few years, with the anticipated release of improved displays and privacy features in upcoming models.

Remaining Challenges and Development Uncertainties
It is not yet confirmed when the next generation of displays suitable for 70° FOV waveguides will be available on the market. The privacy feature planned for future versions is still under development, and the current prototypes lack this functionality. Battery consumption and power management for wider FOV glasses remain unaddressed, and real-world mass production costs are unknown.

Key Questions
When will 70° FOV AR glasses be available to consumers?
Lumus expects to have commercially viable products with 70° FOV by 2026, pending display upgrades and privacy feature development.
Will these glasses be comfortable and lightweight?
Yes, Lumus’s new series “A” waveguides aim to halve lens thickness, making the glasses thinner and lighter, which should enhance comfort.
What are the main technical hurdles remaining?
The key challenges include developing suitable displays for the wider FOV, integrating privacy features, managing power consumption, and ensuring cost-effective manufacturing.
How does this compare to current AR glasses like Meta Ray-Ban?
Current models like Meta Ray-Ban have a 20° FOV and lack privacy features; Lumus’s new waveguides aim for a much wider 70° FOV with privacy in future versions.
Will the waveguides support color and resolution improvements?
Yes, future display upgrades are expected to improve color fidelity and resolution, addressing current prototype limitations.
