South Korean company LetinAR develops optics for AI glasses

Imagine riding a motorcycle at 160 km/h and seeing a turn arrow appear exactly where you need to go on the road. You don't need a phone or a dashboard, just your helmet and a lens the size of a fingernail. This is not just a concept, but a technology expected to appear on European roads this year. According to Techcrunch.com reports .
In recent years, major tech giants have been investing heavily in this field. Meta has been selling AI-powered Ray-Ban glasses since 2023, Google is developing the Android XR platform, and Apple is preparing to enter the market. Samsung is also expected to showcase its first AI glasses, created in partnership with Gentle Monster, at the Galaxy Unpacked event in London this July.
According to Omdia analysts, AI glasses shipments reached 8.7 million units in 2025, an increase of more than 300 percent compared to the previous year. This figure is projected to exceed 15 million this year. Against the backdrop of this growth, component manufacturers are also becoming more active.
South Korean startup LetinAR plays an important role in this direction. Supported by LG Electronics, the company recently raised $18.5 million in funding. LetinAR does not produce the glasses themselves, but an ultra-small optical module that transmits images into the field of view. This component determines the comfort and image quality of the glasses.
Company founders Jaehyeok Kim and Jeonghun Ha believe that AI glasses will become the main platform of the future. Their goal is to solve the most complex engineering problem in the smart glasses industry by creating optical modules that are thinner, lighter, and more energy-efficient than existing technologies.
