This clear bifocal has a magnetic polarized sunglass face that clips on perfectly to the face of the bifocal. This creates a polarized sun bifocal with 100% UV protection. When not needed the polarized clip can be put back into the enclosed sleeve and used later when needed for the outdoors. Most polarized sun bifocals are quite expensive due to the technology involved in manufacturing. This one, however, is accomplished with the magnetic clip and makes it great for outdoors or indoors. The frame is very light weight. Available in Tortoise only. Frame Measurements: 5 1/4" x 1 1/2" (temple to temple x height of lens)
