Think about you’re using a motorbike at 160 kilometers per hour when an arrow seems, floating on the street forward, telling you precisely the place to show. No telephone, no dashboard. Simply your helmet, and a lens the dimensions of a thumbnail.
This isn’t an idea video. It’s heading to European roads as early as this yr. And it’s one early glimpse of the place sensible glasses are heading.
Over the previous few years, Huge Tech has been quietly (and never so quietly) putting 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 shifting 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 yr, and analysts challenge that determine will cross 15 million this yr, per Omdia.
Suppliers and part makers of AI-powered smartglasses are additionally positioning themselves for what comes subsequent. One of many firms, a South Korean startup known as LetinAR, has spent the final decade constructing the optical expertise that might make all of this truly wearable.
The LG Electronics-backed startup simply secured $18.5 million from Korea Improvement Financial institution and the South Korean retail large’s enterprise arm, Lotte Ventures, amongst others, forward of its deliberate 2027 IPO in South Korea.
Its earlier investor, LG Electronics, has since begun creating its personal AI sensible glasses, in line 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 associates 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 part that tasks photos into your field of regard, is what determines whether or not a pair of sensible glasses looks like a sci-fi headset or one thing you’d truly put on to work, Ha informed TechCrunch. It needs to be gentle, skinny, and power-efficient, whereas nonetheless delivering a pointy, clear picture. Getting all of that proper in a single part, sufficiently small to suit inside a normal-looking body, is the central engineering problem of all the 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 right now.”
The co-founders mentioned LetineAR needs to be the corporate these glasses makers name. The corporate calls its expertise PinTILT: a manner of arranging tiny optical parts inside a lens in order that gentle is directed exactly the place it must go, into the person’s eye, fairly than scattered in each path.
Consider a TV. It broadcasts gentle throughout a complete room, however solely the sunshine that really reaches your eyes issues. Most current sensible lens applied sciences, significantly a dominant strategy known as waveguide, work a bit like that TV, splitting and spreading gentle throughout the total lens to create a large picture. The result’s a skinny lens, however an inefficient one. Plenty of gentle will get thrown away earlier than it ever reaches the attention, which suggests dimmer photos and, critically, a battery that drains quick, Ha defined.
The choice, a mirror-based strategy often known as birdbath, delivers gentle extra on to the attention, however the construction is cumbersome, making it practically inconceivable to suit inside one thing that appears like a standard pair of glasses.
PinTILT sidesteps that tradeoff, Ha mentioned. By focusing solely on the sunshine that may truly enter the attention and punctiliously engineering the angle of every tiny aspect contained in the lens, LetinAR claims it could actually 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 all the trade has been making an attempt to resolve.
Within the area, there are a selection of friends like WaveOptics, DigiLens and Lumus.
Clients
Its modules are already delivery. LetinAR counts Japan’s NTT QONOQ Units and Dynabook, previously often known as Toshiba Shopper Options, amongst its clients, giving the corporate actual manufacturing expertise at scale. It’s in talks with Huge Tech firms on R&D of next-generation AI glasses, although it declined to call them.
One in every of LetinAR’s most demanding clients is Aegis Rider, a Swiss deeptech firm spun out of ETH Zurich’s Pc Imaginative and prescient Lab. Aegis Rider is constructing an AI-powered AR helmet that shows navigation, pace, and security alerts instantly in a motorbike rider’s field of regard, not floating on the visor, however anchored to the street itself, as if the data is bodily painted on the world forward.
LetinAR’s module is contained in the helmet. Aegis Rider is concentrating 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, akin to AI glasses, are the following layer that can deliver AI into on a regular basis life.
