Abstract: An eyepiece includes a viewing region to emit display light out of the eyepiece along an eye-ward direction, an input end peripherally located from the viewing region and configured to receive the display light into the eyepiece, one or more optical elements positioned to direct the display light received into the eyepiece out of the viewing region along the eye-ward direction, a first side through which ambient scene light is received into the eyepiece, a second side out of which the ambient scene light and the display light are passed along the eye-ward direction, and a photo-chromic coating disposed on the first side and the second side, the photo-chromic coating to darken in the presence of UV light.

Abstract: A head mounted display (HMD) includes a display module for generating CGI light, an eyepiece, and a frame assembly to support the eyepiece in front of an eye of the user. The eyepiece includes a viewing region to emit the CGI light along an eye-ward direction, an input end peripherally located from the viewing region and optically coupled to receive the CGI light into the eyepiece from the display module, and light bending optics to redirect the CGI light. The eyepiece further includes an ambient scene side through which ambient scene light is received into the eyepiece and an eye-ward side opposite the ambient scene side out of which the ambient scene light and the CGI light are passed along the eye-ward direction. A photo-chromic coating is disposed on the ambient scene and eye-ward sides.
