Abstract: A hinge is provided for pivotally connecting a temple bar and the rims of eyeglass frame including: a first part with an upper flange where a first aperture provides a tight fit for a locking pin head section, and a lower flange provided with a recess for receiving the locking pin cylindrical body, a second part with a second aperture having a higher surface roughness than the locking pin cylindrical body, thereby having a higher surface friction between the bushing and the aperture than between bushing and the locking pin—a bushing with an inner opening, a locking pin having a head section and a cylindrical body The second part arranged with a bushing is inserted between the upper flange and the lower flange of the first part. The locking pin is inserted through the first aperture through the inner opening of the bushing and received in the recess.

Abstract: Spectacles with interchangeable eyeglass lenses (2), where the spectacles comprise a spectacles frame (1) and eyeglass lenses (2), where the eyeglass lenses comprise a mount (3) which is secured to an outer edge of the eyeglass lenses, and where at least one of the mount and the spectacles frame comprises a coupling element (8), which can couple together the mount (3) and the spectacles frame (1), thereby producing a spectacles frame in which the eyeglass lenses can be replaced as desired. Furthermore, the mount or the spectacles frame comprises an oblong recess (5) designed to receive a partial section (7) of the spectacles frame or a bulge on the mount. Said spectacles are suitable for use at work, bicycling in blustery weather, or skiing in harsh sunlight.
