Envision navigating a motorcycle at 160 kilometers per hour, guided by an arrow that seamlessly appears on the road ahead, directing your turns. No reliance on a phone or dashboard, just your helmet integrated with a lens the size of a thumbnail.
This advanced scenario is not a mere conceptual projection; it is slated to arrive on European roads as early as this year. It offers a compelling early glimpse into the transformative future of smart glasses technology.
Over recent years, major technology companies have been strategically investing in this burgeoning field. Meta has been offering AI-enabled Ray-Ban glasses since 2023, Google is actively developing Android XR, and Apple is widely anticipated to enter the market. Last week, reports suggested Samsung is preparing to unveil its inaugural AI-capable smart glasses, co-designed with Gentle Monster, at a Galaxy Unpacked event in London this July. Chinese tech giants such as Huawei, Alibaba, and Xiaomi are also making significant advancements in this sector.
The market's rapid expansion underscores this momentum. Global shipments of AI glasses surged to 8.7 million units in 2025, marking an increase of over 300% from the previous year. Analysts, including Omdia, project this figure will exceed 15 million units in the current year.
Amidst this growth, suppliers and component manufacturers for AI-powered smart glasses are also strategically positioning themselves. LetinAR, a South Korean startup, stands out, having dedicated the past decade to perfecting the optical technology essential for making these devices truly wearable.
The startup, which is backed by LG Electronics, recently secured $18.5 million in funding. This investment round included contributions from Korea Development Bank and Lotte Ventures, the venture arm of the South Korean retail giant, among other participants, as LetinAR prepares for its planned 2027 IPO in South Korea.
Notably, LG Electronics, an earlier investor in LetinAR, has since embarked on developing its own AI smart glasses, according to local media reports. This move signals the profound importance South Korea's largest consumer electronics company places on this product category.
LetinAR was co-founded in 2016 by CEO Jaehyeok Kim and CTO Jeonghun Ha, who have maintained a friendship since their high school years.
LetinAR's core business is not manufacturing the glasses themselves, but rather producing the critical components that enable their functionality. As CTO Jeonghun Ha explained to TechCrunch, the optical module—a minuscule lens component responsible for projecting images into a user's field of vision—is the defining factor in whether smart glasses resemble a bulky sci-fi headset or a practical device suitable for daily wear. Achieving this requires the module to be lightweight, thin, and power-efficient, all while delivering a sharp, clear image. Integrating these demanding specifications into a single component, small enough to fit within conventional eyewear frames, represents the central engineering challenge facing the entire industry, and it is precisely what LetinAR is building.
“We see AI glasses as that next platform,” stated CEO Jaehyeok Kim. “And the optical module is the hardest part to get right as AI glasses makers will need a lens that is thinner, lighter, and more power-efficient than what exists today.”
The co-founders articulated LetinAR's ambition to become the preferred supplier for these smart glasses manufacturers. Their proprietary technology, named PinTILT, involves meticulously arranging tiny optical elements within a lens to precisely direct light into the user's eye, preventing unwanted scattering.
To illustrate, consider a television: it broadcasts light across an entire room, yet only the light reaching your eyes is relevant. Many current smart lens technologies, particularly the prevalent waveguide approach, operate similarly, splitting and spreading light across the entire lens to create a wide image. While this results in a thin lens, it is inherently inefficient, as a significant portion of light is lost before reaching the eye. As Ha elaborated, this inefficiency leads to dimmer images and, crucially, rapid battery depletion.
An alternative, the mirror-based "birdbath" method, delivers light more directly to the eye. However, its bulky structure makes it nearly impossible to integrate into a form factor resembling normal glasses.
PinTILT, according to Ha, ingeniously bypasses these tradeoffs. By concentrating exclusively on the light that can effectively enter the eye and precisely engineering the angle of each minute element within the lens, LetinAR asserts its ability to generate brighter images in a thinner, lighter form factor, all while consuming less power. In an industry where every gram of weight and every hour of battery life is critical, this innovation addresses a fundamental challenge that has long eluded a comprehensive solution.
The competitive landscape in this domain includes notable peers such as WaveOptics, DigiLens, and Lumus.
LetinAR's modules are already actively shipping, with customers including Japan's NTT QONOQ Devices and Dynabook, formerly Toshiba Client Solutions. This demonstrates the company's established manufacturing expertise at scale. Furthermore, LetinAR is engaged in discussions with major technology firms regarding the research and development of next-generation AI glasses, though it has not disclosed their names.
Among LetinAR's most demanding clientele is Aegis Rider, a Swiss deeptech company that emerged from ETH Zurich's Computer Vision Lab. Aegis Rider is developing an AI-powered augmented reality helmet designed to display navigation, speed, and safety alerts directly within a motorcycle rider's field of vision. Crucially, this information is anchored to the road itself, creating the illusion that it is physically painted onto the world ahead, rather than simply floating on the visor.
LetinAR's optical module is an integral component within this innovative helmet. Aegis Rider plans to target the EU and Swiss markets in 2026.
The latest funding round, which elevates the total capital raised to $41.7 million, will be allocated towards scaling operations as the AI glasses market transitions from early adoption to mass production, as stated by CEO Kim. He further emphasized that hardware devices, particularly AI glasses, represent the next crucial layer for seamlessly integrating artificial intelligence into daily life.
