As global shipments of AI-enabled smart glasses soar past 8.7 million units in 2025, South Korean startup LetinAR is positioning itself as a key supplier by developing innovative optical lens technology that promises thinner, brighter, and more battery-efficient smart eyewear.
- AI glasses shipments expected to exceed 15 million units in 2026
- LetinAR's PinTILT optics project brighter images with less power
- $18.5M raised; backed by LG Electronics and Korea Development Bank
What happened
South Korean startup LetinAR has developed a specialized optical module, called PinTILT, designed to enhance the performance and wearability of AI smart glasses. This component projects images directly into the user’s field of vision, overcoming long-standing industry challenges related to size, weight, clarity, and power consumption.
The company, which has backing from LG Electronics and recently raised $18.5 million from Korea Development Bank, Lotte Ventures, and others, aims to serve as a vital supplier in the fast-growing AI glasses market. LetinAR’s lens technology allows for brighter and clearer augmented reality images in designs that resemble conventional eyewear rather than bulky headsets.
Why it matters
Global AI smart glasses shipments jumped more than 300% year-over-year to 8.7 million units in 2025, with projections exceeding 15 million this year. This explosive growth highlights strong consumer and enterprise interest in wearable augmented reality driven by AI capabilities.
However, delivering the core optical component within a sleek, power-efficient package remains a significant engineering hurdle. LetinAR’s PinTILT technology addresses this by focusing light precisely into the eye while reducing energy waste compared to traditional waveguide optics or bulkier mirror-based designs. This innovation is critical to making AI glasses practical for everyday use.
What to watch next
LetinAR plans a public offering on the South Korean stock market in 2027, which could accelerate its growth and industry partnerships. Meanwhile, South Korean consumers may see AI-capable smart glasses hitting roads and retail this year, evidenced by collaborations like Samsung’s upcoming AI glasses with Gentle Monster.
Industry observers should monitor how LetinAR’s optical modules integrate with AI glasses from major technology companies including Meta, Google, Apple, and domestic players like LG Electronics, which is reportedly developing its own AI glasses leveraging LetinAR’s optical innovations. Advances here could define the next era of wearable computing.
