The ‘OVERPASS’ style PROFILO! Sunglass clip-ons are the classic style and can be made for a large number of frames. With 4 hooks and a large frontal bar the overpass clip-on is primarily recommended for frames that have a lot of flex at the nasal piece. With nothing going over the bridge of the frame, the overpass clip-on causes less tension in that area and avoids deforming the client’s frame. The overpass clip-on is not suggested for very straight frames or frames with very large temples.
