Claim 5:
6. A surgical loupes headgear, comprising:
surgical loupes;
a frame configured to support the surgical loupes, the frame including a first temple and a second temple; and
a surgical loupes head strap including:
a first monofilament with a first end and a second end;
a second monofilament with a first end and a second end;
at least one sleeve configured to couple the first monofilament and the second monofilament, wherein the first monofilament and the second monofilament are configured to be adjustably translated within the at least one sleeve in order to adjust the size of the surgical loupes head strap;
a first coupler with a first hole and a second hole, the first hole of the first coupler extending all the way through the first coupler and configured to surround and couple to the first end of the first monofilament which extends all the way through the first hole of the first coupler, wherein the first end of the first monofilament is thermally expanded to retain the first end of the first monofilament within the first hole of the first coupler, the second hole of the first coupler also extending all the way through the first coupler and configured to surround and couple to at least a portion of the first temple which extends all the way through the second hole of the first coupler, wherein the second hole of the first coupler comprises an adjustable coupler including a zip-tie configured to adjustably surround the first temple of the frame; and
a second coupler with a first hole and a second hole, the first hole of the second coupler extending all the way through the second coupler and configured to surround and couple to the first end of the second monofilament which extends all the way through the first hole of the second coupler, wherein the first end of the second monofilament is thermally expanded to retain the first end of the second monofilament within the first hole of the second coupler, the second hole of the second coupler also extending all the way through the second coupler and configured to surround and couple to at least a portion of the second temple which extends all the way through the second hole of the second coupler, wherein the second hole of the second coupler comprises a second adjustable coupler including a second zip-tie configured to adjustably surround the second temple of the frame,
wherein a central axis of the first hole of the first coupler and a central axis of the second hole of the first coupler are non-parallel with an offset angle in the range of 10 to 60 degrees between the central axis of the first hole of the first coupler and the central axis of the second hole of the first coupler, and wherein a central axis of the first hole of the second coupler and a central axis of the second hole of the second coupler are also non-parallel with an offset angle in the range of 10 to 60 degrees between the central axis of the first hole of the second coupler and the central axis of the second hole of the second coupler.
