The eyeglass frame comprises a main frame structure including a main cross bar and hinged temples at its ends, and the separate, detachable frame front comprises rims interconnected by a pair of parallel cross members defining a bridge. A fastener member or pad is secured to the underside of the main cross bar and has a pair of parallel grooves cooparable with the cross members for releasably securing the latter in position. One of the grooves is along the front surface of the fastener member and the other groove lies along the lower surface thereof. The fastener member also has one or more apertures cooperable with teats on an additional (sun) frame front for releasable securing the latter. Alternatively the additional frame front may be pivotally mounted on the fastener member.
