Optivisor lens plates are easily interchangeable. So if you wish to work at a different focal length or a different magnification, simply buy an additional lens. Optivisor lenses are the finest crown glass, ground and polished to precision opthalmic standards.
OptivisorLX acrylic lenses are also available, and they will fit an Optivisor, as well.
