Google Glass (Google, Mountain View, CA) is a wearable technology with a computer and camera mounted on an eyeglass frame. The camera captures wide-angle video and projects it onto a prism located in the right superior temporal quadrant of the wearer's visual field. The authors present a case of an individual who used Google Glass' video projection feature to expand his severely constricted right visual field. This patient reported improved ambulatory navigation. Using Google Glass, the patient's peripheral vision, measured using Goldmann kinetic perimetry, expanded impressively. Based on these preliminary results, the authors propose further characterization on the potential utility of such head-mount display technology as a tool to improve the lives of patients with severely constricted visual fields.
