Think about you’re using a motorbike at 160 kilometers per hour when an arrow seems, floating on the highway forward, telling you precisely the place to show. No cellphone, no dashboard. Simply your helmet, and a lens the scale of a thumbnail.
This isn’t an idea video. It’s heading to European roads as early as this 12 months. And it’s one early glimpse of the place sensible glasses are heading.
Over the previous few years, Large Tech has been quietly (and never so quietly) inserting its bets. Meta has been promoting AI-enabled Ray-Ban glasses since 2023, Google is building Android XR, and Apple is expected to enter the market. Final week, Samsung was reportedly set to unveil its first AI-capable sensible glasses, co-designed with Light Monster, at a Galaxy Unpacked occasion in London this July. China’s Huawei, Alibaba, Xiaomi and others are all transferring too.
The numbers replicate the momentum. International AI glasses shipments surged to eight.7 million items in 2025, up greater than 300% from the prior 12 months, and analysts undertaking that determine will cross 15 million this 12 months, per Omdia.
Suppliers and element makers of AI-powered smartglasses are additionally positioning themselves for what comes subsequent. One of many firms, a South Korean startup referred to as LetinAR, has spent the final decade constructing the optical know-how that would make all of this really wearable.
The LG Electronics-backed startup simply secured $18.5 million from Korea Improvement Financial institution and the South Korean retail big’s enterprise arm, Lotte Ventures, amongst others, forward of its deliberate 2027 IPO in South Korea.
Its earlier investor, LG Electronics, has since begun growing its personal AI sensible glasses, in accordance with a local media report, which is an indication of how severely South Korea’s largest client electronics firm takes the class.
CEO Jaehyeok Kim and CTO Jeonghun Ha, who’ve been mates since highschool, based LetinAR collectively in 2016.
The lens that makes it wearable
LetinAR would not make the glasses. It makes the half that makes the glasses work. The optical module, the tiny lens element that tasks pictures into your visual field, is what determines whether or not a pair of sensible glasses appears like a sci-fi headset or one thing you’d really put on to work, Ha informed TechCrunch. It needs to be mild, skinny, and power-efficient, whereas nonetheless delivering a pointy, clear picture. Getting all of that proper in a single element, sufficiently small to suit inside a normal-looking body, is the central engineering problem of the complete trade. That is what LetinAR is constructing.
“We see AI glasses as that subsequent platform,” Kim mentioned. “And the optical module is the toughest half to get proper as AI glasses makers will want a lens that’s thinner, lighter, and extra power-efficient than what exists as we speak.”
The co-founders mentioned LetineAR desires to be the corporate these glasses makers name. The corporate calls its know-how PinTILT: a method of arranging tiny optical parts inside a lens in order that mild is directed exactly the place it must go, into the person’s eye, slightly than scattered in each path.
Consider a TV. It broadcasts mild throughout a complete room, however solely the sunshine that truly reaches your eyes issues. Most present sensible lens applied sciences, notably a dominant strategy referred to as waveguide, work a bit like that TV, splitting and spreading mild throughout the total lens to create a large picture. The result’s a skinny lens, however an inefficient one. Plenty of mild will get thrown away earlier than it ever reaches the attention, which implies dimmer pictures and, critically, a battery that drains quick, Ha defined.
The choice, a mirror-based strategy often called birdbath, delivers mild extra on to the attention, however the construction is cumbersome, making it almost unattainable to suit inside one thing that appears like a traditional pair of glasses.
PinTILT sidesteps that tradeoff, Ha mentioned. By focusing solely on the sunshine that may really enter the attention and punctiliously engineering the angle of every tiny component contained in the lens, LetinAR claims it will probably produce a brighter picture in a thinner, lighter kind issue, utilizing much less energy. In a class the place each gram and each hour of battery life issues, that is the issue the complete trade has been making an attempt to resolve.
Within the area, there are a selection of friends like WaveOptics, DigiLens and Lumus.
Prospects
Its modules are already transport. LetinAR counts Japan’s NTT QONOQ Gadgets and Dynabook, previously often called Toshiba Consumer Options, amongst its clients, giving the corporate actual manufacturing expertise at scale. It’s in talks with Large Tech firms on R&D of next-generation AI glasses, although it declined to call them.
One in all LetinAR’s most demanding clients is Aegis Rider, a Swiss deeptech firm spun out of ETH Zurich’s Laptop Imaginative and prescient Lab. Aegis Rider is constructing an AI-powered AR helmet that shows navigation, velocity, and security alerts straight in a motorbike rider’s visual field, not floating on the visor, however anchored to the highway itself, as if the data is bodily painted on the world forward.
LetinAR’s module is contained in the helmet. Aegis Rider is focusing on the EU and Swiss markets in 2026.
The most recent funding, which brings the overall raised to $41.7 million, will go towards scale-up because the AI glasses market shifts from early adopters to mass manufacturing, mentioned Kim, including that {hardware} gadgets, similar to AI glasses, are the subsequent layer that may convey AI into on a regular basis life.
