Spectacles e.g. sports glass, has lenses that are insertable into convexity of groove of frame by expansion connection in recess of seat bridge, where lateral contact surfaces of recess have bevels for force-fit retention of lenses
摘要
<p>The spectacles have lenses (2, 3) detachably fixed in a rotary seat bridge in a spectacle rim lying in an outer edge region of a spectacle frame (1). The lenses are held in a mounting position by molded parts. The lenses are insertable into the convexity of a groove of the frame by an expansion connection in a recess (13) of the seat bridge. Lateral contact surfaces of the recess have bevels for force-fit retention of the lenses.</p>
