See-through computer display systems

A wearable head device comprising:

• an optics module comprising:
• a polarized light source configured to provide an illumination light;
• a reflective image source configured to form an image light based on the illumination light;
• and
• a partial reflector configured to transmit the illumination light toward the reflective image source, receive the image light from the reflective image source, and transmit the image light toward a first lens configured to converge the image light;
• a combiner configured to transmit the converged image light, along with an environment light from a surrounding environment, toward a user's eye concurrently with the user wearing the wearable head device;
• and
• a frame configured to hold a second lens,
• wherein:
• the second lens comprises a first region having a first transmissivity configured to occlude viewing of the optics module through the first region of the second lens, and
• the second lens further comprises a second region having a second transmissivity configured to transmit the environment light toward the user's eye concurrently with the user wearing the wearable head device.

A method comprising:

• providing, via a polarized light source of an optics module of a wearable head device, an illumination light;
• transmitting, via a partial reflector of the optics module, the illumination light toward a reflective image source of the optics module;
• forming, via the reflective image source, an image light based on the illumination light;
• receiving, via the partial reflector, the image light from the reflective image source;
• transmitting, via the partial reflector, the image light toward a first lens of the wearable head device;
• converging the image light via the first lens;
• and
• concurrently transmitting, toward a user's eye via a combiner of the wearable head device, the converged image light and an environment light from a surrounding environment, wherein:
• the wearable head device comprises a frame configured to hold a second lens,
• the second lens comprises a first region having a first transmissivity configured to occlude viewing of the optics module through the first region of the second lens, and
• the second lens further comprises a second region having a second transmissivity configured to transmit the environment light toward the user's eye.
