BERNINA’s practical Magnifying Lens Set sharpens your view of the work area. This is especially helpful for precision sewing in tricky places. The lenses also make lighter work of embroidery, sparing your eyes and reducing fatigue. The set contains three magnifying lenses of different strengths, enabling you to choose the most suitable magnification for the project at hand. A mounting bracket (included with some models or sold separately) is required - see your machine's manual for details. Fits all current models.
