The Future of AI-Powered Smart Glasses
Imagine riding a motorcycle at 160 kilometers per hour when an arrow suddenly appears, floating on the road ahead, guiding you exactly where to turn. No phone, no dashboard—just your helmet and a lens the size of a thumbnail. This isn’t a futuristic concept video; it’s a glimpse of what could soon be reality on European roads, signaling the rapid advancement of smart glasses technology.
Over the past few years, major technology companies have been increasingly investing in AI-enabled smart glasses. Meta launched its AI-integrated Ray-Ban glasses in 2023, while Google is actively developing its Android XR platform. Apple is anticipated to enter the market soon, bringing its own innovations. Most recently, Samsung reportedly plans to unveil its first AI-capable smart glasses co-designed with Gentle Monster at the Galaxy Unpacked event in London this July. Meanwhile, Chinese giants like Huawei, Alibaba, and Xiaomi are also intensifying their efforts in this competitive space.
The market momentum is clear. According to Omdia, global AI glasses shipments soared to 8.7 million units in 2025, a staggering increase of over 300% from the previous year. Forecasts predict shipments will surpass 15 million units in 2026, emphasizing the rapidly growing consumer appetite for wearable AI technology.
Behind the scenes, suppliers and component manufacturers are racing to perfect the essential technologies that will make smart glasses practical and desirable. One notable player is South Korean startup LetinAR, which has spent the last decade perfecting the optical technology that could transform wearable AI glasses from bulky prototypes into sleek, everyday devices.
Backed by LG Electronics and supported by investment from Korea Development Bank and Lotte Ventures, LetinAR recently secured $18.5 million ahead of its planned IPO in South Korea in 2027. LG Electronics itself has reportedly started developing its own AI smart glasses, underscoring the serious commitment from one of South Korea’s largest consumer electronics companies to this burgeoning category.
LetinAR was founded in 2016 by CEO Jaehyeok Kim and CTO Jeonghun Ha, longtime friends since high school, who share a vision for revolutionizing the way we interact with augmented reality (AR).
The Lens That Makes It Wearable
LetinAR doesn’t produce the glasses themselves but specializes in the optical module—the tiny lens component that projects images directly into a user’s field of vision. This module is crucial, determining whether smart glasses feel like a cumbersome sci-fi headset or a stylish, wearable device suitable for daily use.
“We see AI glasses as that next platform,” Kim explained. “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 company’s proprietary technology, called PinTILT, arranges microscopic optical elements inside the lens to direct light precisely into the user’s eye, rather than scattering it broadly. This contrasts with the dominant waveguide technology, which works somewhat like a TV broadcasting light across a room. Although waveguide lenses are thin, they waste much of the light, resulting in dimmer images and faster battery drain.
Another approach, known as birdbath, uses mirrors to deliver light more directly but is too bulky to fit inside conventional glasses frames.
PinTILT bypasses these limitations by focusing only on the light that enters the eye, engineering each tiny optical element’s angle to produce a brighter image in a thinner, lighter form factor that consumes less power. In a sector where every gram and every hour of battery life counts, this innovation addresses one of the industry’s most critical challenges.
LetinAR operates in a competitive landscape alongside companies like WaveOptics, DigiLens, and Lumus, all vying to perfect the future of AR optics.
Customers and Market Traction
LetinAR’s optical modules are already in production, supplying companies such as Japan’s NTT QONOQ Devices and Dynabook (formerly Toshiba Client Solutions). This manufacturing experience at scale has positioned LetinAR well for upcoming expansion.
The startup is also collaborating with major tech companies on next-generation AI glasses research and development, though it has not disclosed names.
One of LetinAR’s most ambitious customers is Aegis Rider, a Swiss deep tech company spun out of ETH Zurich’s Computer Vision Lab. Aegis Rider is developing an AI-powered augmented reality helmet for motorcyclists that overlays navigation, speed, and safety alerts directly onto the rider’s field of vision. Unlike traditional heads-up displays, this information is anchored to the road itself, creating the impression that it is physically painted on the world ahead.
LetinAR’s optical module is integral to this helmet, which Aegis Rider plans to introduce to the EU and Swiss markets in 2026.
The latest funding round, bringing LetinAR’s total capital raised to $41.7 million, will support scaling production as AI glasses transition from early adopters to mass-market devices. Kim emphasized that hardware like AI glasses represents the next layer in integrating AI seamlessly into everyday life.
