1. An apparatus for mounting optical loupes to spectacles having a pair of lenses joined by a bridge, said apparatus comprising:

  • a bridge mount configured to be attached to the spectacles proximate the bridge of the spectacles;

    an elongate support member extending along a direction substantially normal to the bridge of the spectacles and pivotally coupled to said bridge mount for pivotal movement about a first axis substantially parallel to the bridge, wherein said support member positionable in any orientation about said first axis, forward of the lenses of the spectacles;

    a saddle slidably received on said support member and movable along a longitudinal direction of said support member;

    a pair of elongate mount bar extensions slidably coupled to said saddle and extending in opposite directions along a second axis substantially transverse to said longitudinal direction of said support member, said mount bar extensions movable along said second axis to thereby vary an interpupillary distance of the optical loupes; and

    a pair of loupe support members pivotally coupled to respective distal ends of said mount bar extensions for rotational movement about respective third and fourth axes substantially perpendicular to said second axis to thereby permit adjustment of a convergence angle of the optical loupes.
