AI Glasses Shipments Surge 263%, Yet 96% Lack Screens: Where Do The Manufacturing Challenges Lie?

In late September 2026, data released by Counterpoint Research indicated that global shipments of AI glasses in the first half of 2026 surged by 263% year-on-year. However, a frequently overlooked detail is that 96% of these shipments consisted of AI glasses lacking a display function. Although both categories are labeled "AI glasses," they differ significantly in terms of product architecture and manufacturing challenges. For the consumer electronics supply chain, the key focus should be on the distinct requirements for processing, assembly, and testing that each of these two product paths entails.

1. First, let’s clarify the two product paths

The absence of a display does not imply simple manufacturing; conversely, the inclusion of a display involves far more than just adding a screen.

Key components of AI glasses without displays include a camera, microphone, speaker, processing chip, battery, and various connectors. Manufacturing priorities here center on miniaturized integration, overall device weight, the assembly of audio and imaging modules, as well as comfort and stability during wear.

AR/AI glasses that feature a display require additional components, such as micro-displays, optical engines, and waveguides. Beyond the challenges mentioned above, these devices also necessitate addressing optical efficiency, image positioning, field of view, light transmission, and consistency across mass production.

In September, Meta announced the expansion of its Ray-Ban smart glasses—which include a display—into markets outside the United States, specifically the UK, Canada, France, Italy, and Germany. While smart glasses with displays are moving toward commercialization, they remain at a different stage of manufacturing maturity compared to the display-less AI glasses that currently account for the majority of shipments.

2. Optical Waveguides: Balancing Lightweight Design with Imaging Stability

The thinner and lighter a lens becomes, the more challenging it is to maintain high standards in optical fabrication and inspection.

Smart glasses with displays often utilize optical waveguides to direct the image output from a micro-display module to the wearer’s field of view. The system must ensure that the external environment remains clearly visible while simultaneously delivering the digital image precisely to the intended position.

Manufacturing Challenges: Achieving the required optical performance in a single lens is merely the starting point. The true test—which determines whether the technology can be scaled for mass production—lies in ensuring consistency across different batches regarding field of view, brightness, color, and image positioning.

3. Micro-displays and Novel Optical Components: The Smaller the Size, the Harder the Alignment

Delivering an image to the human eye requires more than just a sufficiently small display.

Micro-display components, optical coupling structures, and lenses must be precisely positioned and secured within a highly constrained space. Even the slightest assembly deviation can lead to issues such as virtual image displacement, localized blurring, uneven brightness, or stray light.

From micro-displays to advanced meta-optical components, key manufacturing capabilities include precision patterning, thin-film deposition, optical alignment, adhesive bonding/curing, and final imaging inspection. The fact that a laboratory prototype can produce an image does not guarantee that thousands of individual headsets will all perform with the same level of quality.

4. Frame and Eyeglass Legs: Packing More Functionality into Limited Space

While they may look like ordinary eyewear, these devices house a highly integrated electronic system within.

For AI-powered glasses that lack a built-in display, the manufacturing challenges are distinct: the frames must accommodate cameras, microphones, speakers, antennas, and internal wiring, while the temples typically house batteries, circuit boards, and other components.

This necessitates seamless coordination across processes such as precision injection molding, CNC machining, micro-interconnection, the use of flexible circuits, component bonding, and final assembly. Structural elements must not only serve as a precise foundation for mounting components but also balance weight, structural integrity, and the pressure exerted during prolonged wear.

Even if individual parts meet dimensional specifications, the overall user experience can still be compromised by issues such as inconsistent resistance when opening or closing the temples, misalignment between the camera and the frame, deviations in acoustic port positioning, or inadequate thermal management and sealing for the electronic components.

5. Moving to mass production requires passing the hurdle of rigorous testing

Validating AI glasses for mass production involves far more than just a visual inspection.

On the optical side, key factors include imaging clarity, brightness and color uniformity, light transmission, and the alignment precision of optical components. On the electronic and structural side, the focus shifts to the performance of cameras and microphones, acoustic quality, connectivity reliability, the durability of the temple hinges, as well as drop resistance and thermal management. The specific test parameters are determined by the product design and the requirements of the target market.

For manufacturers, the opportunity lies not merely in adopting "new materials" or "new components," but in the ability to maintain a stable process window, ensure reproducible assembly parameters, and provide traceable inspection results.

From a manufacturing perspective, AI glasses are currently following two parallel paths toward industrialization: products without displays prioritize miniaturization and overall cost-efficiency, while those with displays place greater demands on precision optics, alignment, and production yield. Regardless of which path achieves scale first, success hinges on stable and repeatable manufacturing capabilities.

Closing Thoughts

From an industry perspective, the evolution of smart wearable devices is increasingly returning to a human-centric design philosophy.

Breakthroughs in core optical technologies—such as SRG (Surface Relief Grating) waveguides—are reshaping product form factors. The true value of such advanced technology lies in its "invisibility": it is intuitive, easy to use, and does not interfere with the user’s natural behavior. The next phase of AR development hinges on how quickly we can overcome challenges in nanoscale manufacturing. As precision optics, micro-displays, and assembly processes continue to mature, the line between "smart devices" and "conventional eyewear" will gradually blur. This is no longer a question of technical feasibility, but rather one of the pace of industrialization.

SOTECH has consistently kept a close eye on this trend, dedicating itself to the seamless integration of cutting-edge optical technology with user-centric design. Weighing only 45 grams and featuring adjustable silicone nose pads along with a precisely balanced frame, our G-series AI glasses are suitable for both everyday wear and outdoor use—even in direct sunlight. Users frequently report forgetting they are wearing them, even during long shifts in industrial settings.

For partners currently developing smart eyewear, now is a critical window to delve into technical roadmaps and evaluate the feasibility of mass production.
