AI Glasses Optics Maker LetinAR Lands $18.5M Ahead of 2027 IPO
Korean lens maker LetinAR has raised $18.5 million from Korea Development Bank and Lotte Ventures as AI glasses shipments triple, and Indian players from Lenskart to Reliance are watching.
The News
LetinAR, a South Korean optics startup founded in 2016, has raised $18.5 million in a fresh funding round led by Korea Development Bank and Lotte Ventures, taking its total raised to $41.7 million. The company plans to list on a South Korean exchange in 2027.
The Seoul-based firm builds optical modules, the lens components that sit at the heart of AI glasses, using a proprietary technology it calls PinTILT. The system arranges tiny optical elements to channel light to the wearer's eye, producing brighter images while keeping frames thinner, lighter, and less power hungry.
Customers already shipping product with LetinAR optics include NTT QONOQ Devices, Dynabook (Toshiba's PC arm), and Switzerland's Aegis Rider, which is rolling an AI-powered AR helmet into European markets this year. LetinAR has also confirmed it is in talks with unnamed Big Tech buyers, with LG Electronics already on its cap table.
Why It Matters
The funding lands at a fragile inflection point for smart eyewear. Global AI glasses shipments hit 8.7 million units in 2025, a 300% jump year-on-year, with analysts cited by TechCrunch projecting 2026 volumes above 15 million. That surge is straining a supplier base dominated by WaveOptics (owned by Snap), Lumus, and DigiLens.
The last time an optical components race drew this much capital was the 2014 to 2017 wave around Magic Leap and HoloLens, when investors bet billions on waveguide makers only to watch the consumer market stall for nearly a decade. The difference in 2026 is that Meta has already proven a mass market exists. Ray-Ban Meta frames turned eyewear from a curiosity into a sales line item for opticians, which is why the supplier scramble matters now.
For LetinAR, the IPO timeline tells the story. Going public in 2027 only works if at least one Tier-1 device maker designs PinTILT into a high-volume product before then. CEO Jaehyeok Kim told TechCrunch that "the optical module is the hardest part to get right", which is essentially the whole investment thesis.
Indian Angle
For India, the useful frame here is not "we should build glasses" but "we are already in this supply chain whether we want to be or not". Lenskart, the Faridabad-based eyewear giant, owns Owndays in Japan, which already retails AI-enabled prescription frames. If Lenskart wants its own house-brand AI eyewear by 2027, it will be sourcing from a company that looks a lot like LetinAR.
The second angle is manufacturing. India's Production Linked Incentive scheme for electronics components, expanded by the Ministry of Electronics and IT in 2025, explicitly covers optical lens assemblies. A Korean supplier with a 2027 IPO target needs a low-cost assembly partner, and Indian electronics manufacturing services firms like Dixon Technologies and Optiemus Infracom have pitched themselves to Korean buyers on display and battery lines. Optical modules are a natural next step.
Third, there is the homegrown side. Mumbai's AjnaLens and Bengaluru's Tesseract (now inside Reliance Jio as JioGlass) face the same lens-cost problem LetinAR has now partly solved. Whether they source from Korea or build indigenously will shape whether India is a hardware participant in the AI glasses era or merely a market for it.
FAQ
When does this funding take effect?
The $18.5 million round closed in May 2026 with Korea Development Bank and Lotte Ventures as lead investors. The capital is earmarked for scaling PinTILT module production ahead of LetinAR's planned 2027 listing on a South Korean exchange.
How does LetinAR compare to rivals like WaveOptics?
WaveOptics, owned by Snap since 2021, plus Lumus and DigiLens, are the dominant waveguide suppliers. LetinAR's pitch is not waveguide based. PinTILT uses an array of micro-mirrors instead, which the company claims allows for thinner frames and better power efficiency at lower cost.
What does this mean for Indian eyewear makers?
For Lenskart and others targeting AI-enabled frames, LetinAR represents one of few merchant suppliers of advanced optics. Indian brands that want to launch own-label AI glasses by 2027 will either need to source modules from companies like LetinAR or wait for indigenous alternatives to mature.
