Donegan OptiVISOR® with Four Acrylic Lens Plates

This OptiVISOR®, the first choice of many jewelers for magnification at the bench, comes with four interchangeable, lightweight acrylic lens plates that provide a range of magnification from 1.75X–2.75X. The lenses snap in and out of the OptiVISOR frame quickly and securely, making it easy to change lenses as often as your work demands; all 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 work piece. 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. Included lenses are:

• #3 lens plate, 1.75X; focal length 14".
• #4 lens plate 2.0X; focal length 10".
• #5 lens plate 2.5X; focal length 8".
• #7 lens plate 2.75X; focal length 6".
