Eyewear with integrated heads-up display

A device comprising:

• a transmissive optical element;
• a frame configured for wearing by a user such that the frame supports the transmissive optical element in a viewing position in which a field of view of the user is at least partially covered by the transmissive optical element;
• and
• an integrated near-eye display mechanism configured for displaying visual information coincident with the transmissive optical element in a display area that is elongate and that extends substantially laterally across at least a part of the field of view of the user, the display mechanism comprising:
• a partially transmissive display reflector carried by the transmissive optical element and configured operatively to reflect towards the user light projected on to a reflective surface of the display reflector, the display area of the display mechanism being defined by a visible extent of the display reflector from a perspective of the user;
• and
• a projector assembly supported by the frame such that the projector assembly is, from the perspective of the user, located substantially above the display reflector, the projector assembly being configured to project computer-generated images on to the reflective surface of the display reflector.
