These are clip-on polarized lenses that clamp onto prescription glasses, giving you sunglass protection without a second pair of frames. The rectangle lens measures 52mm wide and 30mm high, with a 16mm bridge and a 120mm total frame. Polarization cuts glare from water, snow and the road, and the lenses block 100% of UVA and UVB. They suit glasses wearers who want one pair to carry and who keep their prescription frames. Against dedicated prescription sunglasses, they are lighter to pack and cheaper to own, but they add bulk and weight to the front of your glasses and only fit frames whose lens shape matches the clip.
