South Korean Startup Tackles a Stubborn Problem in AR Glasses

LetinAR, a Seoul optics firm, has developed Pin Mirror lenses that let users focus on virtual objects held at arm's length without eye strain. The technology solves convergence-accommodation conflict—the fatigue that occurs when your eyes struggle to focus at close range through AR glasses. The polymer-based approach, award-winning at CES and SPIE, removes a significant hurdle for workplace AR adoption.
