Abstract
Techniques and mechanisms for fabricating an eyepiece from a lens blank including blank bodies that are bonded to each other. In an embodiment, the blank bodies are formed by injection molding and adhered to one another. Fabrication of the eyepiece includes variously machining the blank bodies to shape respective lens bodies of the eyepiece. One or more blocking structures are coupled to reinforce the lens blank during at least part of such machining. In another embodiment, any blocking structures that are to resist forces of a particular machining process are coupled only indirectly to one of the blank bodies.
