South Korean Startup Solves AR's Close-Range Comfort Problem

LetinAR, a Seoul-based optics firm founded in 2016, has developed Pin Mirror lens technology enabling interaction with virtual objects at 25 centimeters without convergence-accommodation conflict—the visual fatigue that has plagued AR glasses during near-distance work. The polymer-based approach, recognized with CES and SPIE awards, addresses a critical barrier to enterprise AR adoption where prolonged close-range interaction is routine.
