The ever-popular OptiVISOR® is the first choice of many jewelers for magnification at the bench. The interchangeable, lightweight glass lens plates are ground and polished to prismatic optical standards to provide clearer, sharper optics. An adjustable tension pivot assembly keeps the visor in the desired position for optimal viewing of your workpiece. The genuine leather band is comfortable to wear, and a self-locking dial adjustment provides a good fit on any size head and over eyeglasses. This OptiVISOR includes one 3.5X (#10) lens plate; additional lens plates are available to enable optimal magnification on a variety of tasks.
For best results, choose the lens the with the lowest power necessary to accomplish your task. This is because the greater the magnification you use, the shorter your focal length will be and the smaller your field of view will be. Choosing the minimal magnification ensures the best possible field of view and focal length as you work.
