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.

An eyewear system including eyeglasses and a case, the eyeglasses having a first lens, a second lens, and a bendable bridge disposed between the first lens and second lens, the bendable bridge having a spring providing a spring force when the bridge is bent from a rest position, the eyeglasses being adapted to move from a wearable configuration in which the first and second lens do not overlap to a stored configuration in which the first and second lenses at least partially overlap, the bendable bridge being bent from its rest position in the stored configuration, the case having an opening through which the eyeglasses pass during insertion and guides sized and configured with respect to the eyeglasses to engage and fold the eyeglasses against spring force of the bridge to the stored configuration during insertion of the eyeglasses through the opening and into the case.

Reversible orientation eyewear for which each of the temple arms moves from an initial orientation relative to the lens frame to a reverse orientation relative to the lens frame by undergoing movements that include rotating a locking piece from the one of the two relative positions to the remainder of the two relative positions and thereby becoming free of magnetic attraction by the magnetically attractive elements; pivoting the temple arms about associated ones of the two ends of the lens frame; and rotating the locking piece from the remainder of the two relative positions to the one of the relative positions to restore magnetic attraction by the magnetically attractive elements.

An energy dispersion mechanism can be integrated into the eyewear design to incorporate a more resilient lens holding structure that can disperse the energy received during an impact and retain the lens in place. The energy dispersion mechanism comprises an impact dispersing material seated within a groove of a first frame portion, the impact dispersing material extending beyond the first frame portion to form a nose bridge which joins the first frame portion to a second frame portion; and the impact dispersing material is seated within a groove of a second frame portion. The impact dispersing material may be overmoulded on the eyewear to allow efficient manufacturing.

The eyewear material is an eyewear material containing thermoplastic polyurethane. The eyewear material has a tan δ peak at both less than 0° C. and 0° C. or more and 70° C. or less observed in dynamic viscoelasticity measurement in tensile mode under the measurement conditions of a temperature increase speed of 5° C./min and a measurement frequency of 10 Hz.

The present invention discloses a floatable eyeglasses structure. It has an overall density less than or equal to a density of the water and comprises an eyeglasses frame and two temples. Each of the two temples comprises a front temple hinged to the eyeglasses frame, a rear temple and a sealing ring. The front temple or the rear temple has a slot, and the other one has an insertion block for correspondingly inserting into the slot. The sealing ring is further provided between the slot and the insertion block to form a sealed hollow cavity therebetween.

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.

Disclosed herein is a process to modify a pair of eyeglasses having a first color to produce a pair of modified eyeglasses having at least the portion of the frame comprising a second color. A kit to modify a pair of eyeglasses is also disclosed.

3D glasses including features for an enhanced viewing experience with lower production and operating costs for theaters. Keyed lenses and removable temples facilitate assembly and field repairs. Specific angles of lens placement and the provision of specific anti-reflective areas on the frames enhance the quality of the optical path content being viewed. RFID and radio chips increase accountability and collection of use statistics. Smooth areas enhance cleaning and lower the time and material costs for between use cleanings.
