ABSTRACT:
A detachable magnetic hinge system for rotatably coupling objects, such as primary eyewear and auxiliary eyewear includes first and second hinge members which are magnetically coupled to one another. The first hinge member is associated with the first object and has at least six generally planar outwardly-facing facets. The second hinge member is associated with the second object and has a plurality of generally planar inwardly-facing facets configured to detachably overlie less than all of the outwardly-facing facets of the first hinge member. Due to the magnetic coupling, selective segmented rotation of the second hinge member relative to the first hinge member is provided.
