Pairs of foldable glasses are provided. The pair of foldable glasses includes two lenses surrounded by a frame, the two lenses having a first side and a second side, the first side facing outwards and the second side facing the wearer, a hinged bridge for connecting the lenses together and permitting the lenses to fold together, and two temple pieces extending from an outer edge of the frame with a hinged connection between each of the temple pieces and the outer edge of the frame enabling the two temple pieces to fold inwards or forwards, wherein the two temple pieces have a hinged joint permitting a rear section of the temple pieces to fold forwards underneath the temple pieces, wherein the rear sections each include a loop configured to enable the pair of foldable glasses to be secured to a separate device.

An eyeglass apparatus comprises first and second eyeglass portions, each having a connector portion and a lens portion. The eyeglass apparatus is configured to transition between stowed and extended configurations. When the eyeglass apparatus is in the stowed configuration, the lens portions overlie one another. When the eyeglass apparatus is in the extended configuration, the lens portions are in a non-overlying configuration.

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.

Disclosed is a spectacle frame including a pair of lens holding rims interconnected by a bridge, each rim being encircling and holding a lens in a central aperture of the rim, each rim being linked laterally to a temple, each rim having at least one cut allowing expansion of the central aperture or retraction and closure of the central aperture by closing the cut. The spectacle frame further includes a lock allowing closure and locking the cuts of the rims. The bridge attaches to the rims to allow attachment of one bridge chosen among bridges having different shapes and/or sizes and/or decorations to adapt the spectacle frame to different morphological features of wearers and/or to choices of the wearers, and wherein the rims and the bridge includes complementary bridge connector to attach and connect the bridge to each rim. A kit of parts and an eyewear are also disclosed.
