Abstract
A frame of a pair of glasses has a pair of eye rims with front surface and nasal regions which are connected together by a bridge with a front surface and a nasal region. The frame has a shallow rabbet which extends from the nasal region of one eye rim, through the nasal region of the bridge, into the nasal region of the other eye rim, and has a predetermined depth. The shallow rabbet has a forward rabbet wall spaced from the front surface of the eye rims and the bridge, and a saggital rabbet wall, which is substantially longer than the forward rabbet wall. The saddle strap pad, made of plastic, is glued at its forward edge region into the shallow rabbet, and in the area of the forward end region is thicker than the depth of the rabbet. The saddle strap pad has a Shore D hardness in the range 10-30, preferably about 20.
