I’m thinking of getting an Optivisor or similar for gunsmithing and fly tying. I’m curious what other members here use? One of my gunsmithing friends, retired now from that career, used an Optivisor with a number 3 lens (1.75X magnification) for general work, and switch to a number 5 lens (2.5X magnification) for fine work. He also noted that he wore bifocals under the Optivisor, therefore the magnification was additive. If anyone here can share what works, or doesn’t work, for them I’d appreciate it!
