Abstract: There is provided a front piece for spectacles, particularly protective spectacles and sport goggles, the front piece for spectacles being adapted for commercialization with a kit of interchangeable lenses in order to adapt for many uses of the spectacles. The front piece for spectacles includes a pair of adjoining rims each formed of inner and outer lateral sides and an interconnecting lower arch having a groove formed in the lateral sides and lower arch for receiving a corresponding lens. The groove is interrupted by a locking pip so that upon bending the front piece slightly a lens can be removed or inserted by articulation with the locking pip. An upper arch is disposed between the lateral sides of the rim and adjacent the plane defined by the groove in the lateral sides and lower arch of the rim. The upper arch may have a design in the form of writing, etc. in relief so as to aerate the lens.
