A covered electric wire contains a conductor and an insulation covering which covers an outer surface of the conductor. The covered electric wire has a flat portion where a cross section of the conductor intersecting an axial direction of the covered electric wire has a flat shape which has a larger length in a width direction. The insulation covering contains, in the cross section of the flat portion, plane regions which contains, at the surface thereof: a width-directional region along the width direction; and a height-directional region intersecting the width direction. The insulation covering contains a region having a rounded shape having a radius at the junction between the width-directional region and the height-directional region, and the covered electric wire satisfies a relationship of R>t between the radius R and a thickness t of the insulation covering at the plane region. The wire harness contains the covered electric wire.

A wire harness including: a core wire having a flat straight section whose vertical height is smaller than a width thereof and a bend bent from an end of the straight section, wherein: the straight section is formed from a second assembled wire obtained by twisting or braiding together first assembled wires which are each obtained by twisting or braiding wire strands, and the bend is formed from a plurality of adjacent wires arranged adjacently in a direction orthogonal to a vertical direction.

Eyewear devices including a tether and methods for identifying proper installation of the tether are disclosed. An eyewear device includes transmission lines extending through the temples to electrical and electronic components positioned adjacent to edges of a frame. A tether is attached to the temples to enable power and communication flow between the electrical and electronic components rather than through the frame. Proper installation is identified based on communications passing between the electrical and electronic components via the tether.
