Think about you’re using a bike 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 yr. And it’s one early glimpse of the place good glasses are heading.
Over the previous few years, Huge Tech has been quietly (and never so quietly) inserting its bets. Meta has been promoting AI-enabled Ray-Ban glasses since 2023Google is building Android XRand Apple is expected to enter the market. Final week, Samsung was reportedly set to unveil its first AI-capable good glasses, co-designed with Mild Monster, at a Galaxy Unpacked occasion in London this July. China’s Huawei, Alibaba, Xiaomi and others are all transferring too.
The numbers mirror the momentum. World AI glasses shipments surged to eight.7 million models in 2025, up greater than 300% from the prior yr, and analysts challenge that determine will cross 15 million this yr, for Omdia.
Suppliers and element makers of AI-powered smartglasses are additionally positioning themselves for what comes subsequent. One of many corporations, a South Korean startup referred to as LetinARhas spent the final decade constructing the optical know-how 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 big’s enterprise arm, Lotte Ventures, amongst others, forward of its deliberate 2027 IPO in South Korea.
Its earlier investor, LG Electronicshas since begun growing its personal AI good glasses, in keeping with a local media report, which is an indication of how critically South Korea’s largest shopper electronics firm takes the class.
CEO Jaehyeok Kim and CTO Jeonghun Ha, who’ve been pals since highschool, based LetinAR collectively in 2016.
The lens that makes it wearable
LetinAR does 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 good glasses looks like a sci-fi headset or one thing you’d truly put on to work, Ha instructed 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 your complete business. That is what LetinAR is constructing.
“We see AI glasses as that subsequent platform,” Kim stated. “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 at this time.”
The co-founders stated 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, somewhat than scattered in each route.
Consider a TV. It broadcasts mild throughout a whole room, however solely the sunshine that truly reaches your eyes issues. Most present good lens applied sciences, notably a dominant strategy referred to as waveguidework a bit like that TV, splitting and spreading mild throughout the complete lens to create a large picture. The result’s a skinny lens, however an inefficient one. Loads 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 generally known as birdbathdelivers mild extra on to the attention, however the construction is cumbersome, making it almost inconceivable to suit inside one thing that appears like a standard pair of glasses.
PinTILT sidesteps that tradeoff, Ha stated. By focusing solely on the sunshine that may truly enter the attention and punctiliously engineering the angle of every tiny component contained in the lens, LetinAR claims it might produce a brighter picture in a thinner, lighter type issue, utilizing much less energy. In a class the place each gram and each hour of battery life issues, that is the issue your complete business has been attempting to resolve.
Within the house, there are a variety of friends like WaveOptics, DigiLens and Smooth.
Prospects
Its modules are already transport. LetinAR counts Japan’s NTT QONOQ Gadgets and Dynabook, previously generally known as Toshiba Consumer Options, amongst its clients, giving the corporate actual manufacturing expertise at scale. It’s in talks with Huge Tech corporations on R&D of next-generation AI glasses, although it declined to call them.
One among LetinAR’s most demanding clients is Aegis Ridera 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 bike 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 whole raised to $41.7 million, will go towards scale-up because the AI glasses market shifts from early adopters to mass manufacturing, stated Kim, including that {hardware} gadgets, equivalent to AI glasses, are the subsequent layer that can carry AI into on a regular basis life.
