MIAMI-Heru Inc., the developer of wearable AI-powered vision diagnostics and augmentation software, closed its Series A financing of $30 million to advance the company's eye diagnostic and vision correction technology platform. An estimated 450 million people worldwide experience visual field defects or double vision, according to Heru, but limited access can mean long waits for eye appointments. Heru's patented autonomous AI-powered vision diagnostics and augmentation software, designed for use on commercially available AR/VR devices, helps ensure that patients' vision can be tested earlier so that diagnosed defects can be treated in a timely manner, the company said.
