Abstract
This study presents a smart contact lens platform designed to correct ocular motor anomalies. The lens is wirelessly powered via a 380 MHz geometric frame resonance, with the eyeglass rim acting as the primary radiating antenna. The lens incorporates an application-specific integrated circuit (ASIC), a micro-light-emitting diode (micro-LED) and a receiver coil. This configuration achieves substantially higher radiation efficiency than 13.56 MHz systems, while maintaining a peak specific absorption rate (SAR) of 0.195 W/kg. This level of SAR is compliant with Federal Communications Commission (FCC) and International Organization for Standardization (ISO) 14708-3 standards. A four-photodetector array with EMA and Kalman filtering enables robust, real-time gaze tracking with minimal jitter, providing precise, ocular-movement-based control. Upon the detection of a predefined event, the micro-LED mounted on the eyeglasses delivers visual feedback that can be acknowledged via eye movement, thereby establishing a bidirectional human–device interaction. This integrated demonstration, which combines wireless power delivery, gaze-based sensing and LED feedback within strabismus and ocular oscillation correction protocols, confirms the feasibility of the platform as a self-contained, interactive therapeutic interface.
