An exemplary eyewear system includes a user interface and a composite lens. A first layer of the composite lens changes opacity in response to a signal. A second layer of the composite lens is a transparent display. The eyewear system further includes a camera, a processing device, and a memory. The processing device receives input via the user interface and, in response to the received input, sends a signal to the first layer of the composite lens to change the opacity of the first layer to cause the composite lens to be at least partially opaque, activates the camera, enhances video feed captured by the camera to increase the contrast of at least a portion of each of a plurality of frames of the video feed, and displays the enhanced video feed in real time using the second layer of the composite lens.
