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 2X (#4) lens plate; additional lens plates are available to enable optimal magnification on a variety of tasks.
