Eyewear with integrated heads-up display

An eyewear device comprising:

• an eyewear frame configured for head-mounted wear;
• a lens mounted on the eyewear frame to occupy a field of view a wearer of the eyewear device, the lens providing an optical medium for display light traveling within the lens, and the lens being transmissive to ambient light;
• and
• an integrated near-eye display mechanism configured to display visual information to the wearer, the display mechanism comprising:
• a display structure that is located within the lens and that is configured to direct into view of the wearer display light incident thereon while traveling within the optical medium provided by the lens, the display structure being transmissive to ambient light traveling through the lens, the lens thus being display-enabled;
• and
• a projector that is housed by the eyewear frame and that is configured to project display light for computer-generated imagery directly into the optical medium, such that a path travelled by the display light comprises, sequentially:
• from the projector into the optical medium of the lens at projector-lens interface located within the eyewear frame, the display light traveling between the projector and the projector-lens interface without exiting an interior volume of the eyewear frame and without entering any intervening optical medium external to the eyewear frame;
• from the projector-lens interface, via the optical medium provided by the lens on to the display structure, from the display light thereupon being redirected by the display structure the wearer;
• and
• from the display structure towards the wearer, the display light exiting the optical medium to enable viewing of the computer-generated imagery by the wearer.
