Clips to spectacles (or to a stand, included), 5X or 7X, fully adjustable

Summary Choice of two sizes. 7X20 (7X magnification, 20mm diameter lens, working distance 1.5 inches ) 5X30 (5X magnification, 30mm diameter lens, working distance 2 inches)  Comments Ingenious mechanism, two ball bearings, easily adjustable to any angle, far better than the model with the fixed clip. Clip it to your spectacles (left or right), or clip it to the wooden stand (included) for use as a hands-free desk magnifier for close-up viewing of small objects.  Further information Everything you need to know about magnifiers and magnification.
