Genuine Donegan Optivisor comes complete with 4 lens plates. Easily change each lens plate to give you the magnification or focal distance that you need in that moment. Like the glass version of the same lenses, these acryic lens plates are prismatic, so they reduce eye strain Together with the padded leather headband, this means you can wear the visor in comfort for extended periods of time. Value priced, this set is the latest addition to the Donegan line of visor magnifiers. The visor itself is exactly the same as the visor that is sold with glass lens plates, and so it is ideal for use with the breathtaking Quasar lighting system.
The greater the magnification, the closer the working distance. Order an Optivisor with a comfortable working distance, and order an Optiloupe that you can occasionally flip down to view objects at a higher magnification but at a closer focal distance. If you ever decide that you need your work to be at a different focal distance, you can always order a different lens plate, which affixes easily.
