The Optivisor from Donegan is the number one choice for jewelers and craftsmen in head mounted magnifiers. The Optivisor uses a specially ground and polished lightweight glass lens that provides the best optical clarity and durability. OptiVisors are the only head mounted magnifier that uses optical glass prismatic lenes. All other head mounted magnifiers use plastic lenes. Optivisors can be worn over glasses and are sold in a variety of magnifications. Lens plates are easily changed.

Product Note: When choosing the right Optivisor lens to use, it is best to think of the working distance you will be most comfortable with. Although a high magnification might seem desirable, sometimes you might not want to be 4" away from your work. Other times, you may want to be that close. The most popular lens has a working distance of 8" (DA 5), followed by 14" (DA 3), 10" (DA 4), 4" (DA 10) then 20" (DA 2). The distance given is the ideal length objects are in focus measured from the lens plate, not your eyes. For added magnification, add the included Optiloupe.

The OptiVISOR is manufactured in six different powers for use in different applications. The number in the upper left-hand corner of the lens plate indicates the approximate diopter power of the lens.
