An assembly for eyeglasses temple includes a first connecting rod and a second connecting rod each having an elastic component, outer ends of the two elastic components are hooked to each other to cause the second connecting rod and the first connecting rod abut against each other. A protrusion is provided on an end portion of the second connecting rod, when the second connecting rod is rotated to a position perpendicular to the first connecting rod, the protrusion is inserted in and limited by an outer peripheral side surface of an end portion of the first connecting rod.

An artifact mitigation system includes a projector assembly and a set of imaging optics optically coupled to the projector assembly. The artifact mitigation system also includes an eyepiece optically coupled to the set of imaging optics. The eyepiece includes a diffractive incoupling interface. The artifact mitigation system further includes an artifact prevention element disposed between the set of imaging optics and the eyepiece. The artifact prevention element includes a linear polarizer, a first quarter waveplate disposed adjacent the linear polarizer, and a color select component disposed adjacent the first quarter waveplate.

An example embodiment includes eyewear. The eyewear includes a lens, a brow piece, and two temple assemblies. The brow piece is configured to position the lens in front of the eyes of a user during use. The two temple assemblies are coupled to the brow piece by two hinges. Each of the temple assemblies are configured to extend along a side of a head of the user during use. Each of the temple assemblies includes a temple substrate and a wave-shaped insert. The wave-shape insert includes at least one horizontal span and at least one vertical portion. The horizontal span is configured to dictate the deflection of a first portion of the temple substrate and enable rotation of the first portion of the temple substrate about the horizontal span. The vertical portion is configured to dictate a torsional stiffness of a second portion of the temple assembly.

Eyeglasses with replaceable temples, and exemplary mechanisms to attach a frame-connected portion to a replaceable temple portion, are presented. An eyeglass frame can be attached to a hinged metal piece. The hinged metal piece can have a front solid portion and a rear bezel, including a spring and mesa portion. The spring and mesa portion can include a resilient spring material and an upwardly protruding mesa, and can be inserted into a cavity in a temple piece, and locked into place. By providing numerous temple pieces having essentially the same cavity dimensions, the eyeglasses can be used with an assortment of interchangeable temple pieces, which can be changed at will, effectively giving a wearer many looks and styles from the same basic frame, with the same lenses.
