A user-wearable display device comprising: a frame configured to mount on the user ; an augmented reality display attached to the frame and configured to direct images to an eye of the user ; a sensor configured to obtain information about ambient light conditions in an environment surrounding the user , the sensor comprising an image capture device configured to capture an image of a scene in a field of view of the user ; a variable optical material that undergoes a physical and/or a chemical change in response to a stimulus; a source configured to provide the stimulus; and processing electronics configured to: determine based on the information obtained from the sensor that the ambient light conditions on a portion of a display lens are bright or that a bright object is in the field of view of the user and is aligned with a portion of the display, provide the stimulus that can change at least one of: the intensity of ambient light transmitted through that portion of the display lens , spectral content of ambient light transmitted through that portion of the display lens , or the optical path of the ambient light transmitted through that portion of the display lens to reduce intensity of ambient light transmitted through that portion of the display lens and/or from the bright object and improve visual experience. a frame configured to mount on the user ; an augmented reality display attached to the frame and configured to direct images to an eye of the user ; a sensor configured to obtain information about ambient light conditions in an environment surrounding the user , the sensor comprising an image capture device configured to capture an image of a scene in a field of view of the user ; a variable optical material that undergoes a physical and/or a chemical change in response to a stimulus; a source configured to provide the stimulus; and processing electronics configured to: determine based on the information obtained from the sensor that the ambient light conditions on a portion of a display lens are bright or that a bright object is in the field of view of the user and is aligned with a portion of the display, provide the stimulus that can change at least one of: the intensity of ambient light transmitted through that portion of the display lens , spectral content of ambient light transmitted through that portion of the display lens , or the optical path of the ambient light transmitted through that portion of the display lens to reduce intensity of ambient light transmitted through that portion of the display lens and/or from the bright object and improve visual experience. determine based on the information obtained from the sensor that the ambient light conditions on a portion of a display lens are bright or that a bright object is in the field of view of the user and is aligned with a portion of the display, provide the stimulus that can change at least one of: the intensity of ambient light transmitted through that portion of the display lens , spectral content of ambient light transmitted through that portion of the display lens , or the optical path of the ambient light transmitted through that portion of the display lens to reduce intensity of ambient light transmitted through that portion of the display lens and/or from the bright object and improve visual experience. <EOS>
