Abstract
Disclosed are dimensionally stable eyeglass orbitals, pivotably mounted in an eyeglass frame. In one embodiment, the eyeglass orbitals are investment cast from substantially pure titanium or a titanium based alloy. The orbitals hold the lenses in the as-worn orientation such that the optical centerline of each lens extends in a predetermined relationship with respect to the wearer's theoretical straight ahead line of sight.
Claims21
An eyeglass, containing a nonpowered decentered eyeglass lens which is optically corrected in an as-worn orientation with respect to the normal line of sight of a wearer, comprising:
- an investment cast metal frame;
- and
- at least one lens attached to the frame and positioned by the frame such that the lens is adapted to have a predetermined orientation with respect to the wearer's normal line of sight, said lens having an outer surface conforming to a portion of the surface of a first sphere having a first center and an inner surface conforming to a portion of the surface of a second sphere having a second center, and an optical centerline extending through the first and second centers;
- wherein the frame maintains the lens in an as-worn orientation such that the optical centerline is adapted to be maintained substantially parallel to and spaced vertically and horizontally apart from the wearer's normal line of sight.
An eyeglass containing a nonpowered decentered eyeglass lens, comprising:
- a frame adapted to permit limited bending movement upon application of an external force, said frame being biased to return to a predetermined configuration upon removal of the external force;
- and
- at least one lens attached to said frame, said lens having an outer surface conforming to a portion of a surface of a first sphere having a first center and an inner surface conforming to a portion of a surface of a second sphere having a second center, and an optical centerline extending through the first and second centers;
- wherein said frame is adapted to maintain said lens in an as-worn orientation with both wrap and rake such that the optical centerline is substantially parallel to and spaced vertically and horizontally apart from the wearer's normal line of sight.
