摘要： 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.

摘要： The present invention relates to an optical device usable in a head-mounted display which comprises a light conducting element and at least one wafer, and to a head-mounted device which is configured to provide an informative display of augmented reality for a wearer of the head-mounted device and which comprises such an optical device. This optical device (1) comprises: a light conducting element (4) which has two first and second opposite main faces (4a and 4b) and which inputs and conducts by total internal reflections a light (6) received from the light source (5) and partially outputs it out of said element, at least one wafer (2, 3) which comprises an internal surface (2a, 3a) facing a said first main face of said light conducting element, and interposition means in contact with said first main face and said internal surface and defining a gap (11a, 11b) optically isolating said element. According to the invention, said interposition means comprise a peripheral sealing arrangement (10a, 10b) which extends along its peripheral length between and in sealing contact with a peripheral area (2aa, 3aa) of said internal surface and a facing zone (4aa, 4ba) of said first main face, at least one portion of said sealing arrangement exhibiting a locally reduced optical coupling with said first main face to preserve said internal reflections at said at least one portion toward the inside of said element.
