Patent application: Cosmetic holographic wearable ocular devices

Ben Welter - Sunday, May 10, 2020

U.S. patent application 20200132897 (applicant TruIris LLC, Columbus, Ohio):

"Wearable ocular devices (such as ocular prostheses or contact lenses) utilizing diffraction gratings to produce color, as well as methods for producing such devices, are provided. A diffraction grating on the device may diffract the incident light to the observer. The result may be colored light that appears to originate from the wearer's eyes. The diffraction grating may achieve a look or feeling that is qualitatively or quantitatively different from the look or feeling achieved by previous devices that use dyes or inks."
