Some of my faceting students who don't wear glasses purchase cheap drug store glasses and remove the lenses so they can use the Bausch and Lomb Glasses Loupe.

GemologyPro/Harald Schneider L1 10X Loupe
This is the finest loupe available. It is prized by diamond graders and discriminating professionals. Those who use a loupe all day long will rarely get eyestrain with the L1 loupe.

The wide 20mm diameter provides a bright image. The German designed aplanatic/achromatic lens is astoundingly sharp. The depth of field and edge to edge sharpness is unsurpassed.

A neck strap is easily attached to the loupe for ease of use. Shown to the left.

OptiVisors
OptiVisors provide convenient magnification because they are worn on the head and can be easily flipped up and out of the way when not in use. OptiVisors feature high quality glass optics and are available in different magnifications as listed below.

Note: All other inexpensive and moderately priced visor-style magnifiers use inferior plastic lenses. So, even though OptiVisors are a little more expensive than similar looking products, they are far superior in optical quality, don't scratch as easily and are less prone to creating eye strain.

We also have the bright Xenon Laserbeam VisorLight accessory which clips onto OptiVisors to better illuminate and inspect your work piece. The VisorLight requires two AA size batteries.
