Re: Off topic - magnifying glasses

I also agree that getting Optivisors is well worth the investment as they are quite well made and last.? ?The ¡°sizes¡° that are shown are in Diopters, so be aware that each size has a different working focal length ranges.? If you want more magnification you will have to hold the object to be magnified closer to your face.? There is a table on the Optivisor web page that shows this information along with the different models and accessories.? I use a #3 most of the time.? The Optivisor lenses are glass, so they will not scratch easily like the cheaper plastic lenses. ? Jerry F. ? ? ?

Subject: Re: [Unimat] Off topic - magnifying glasses? I can second that ! I have visors in sizes 3, 5 and 7.? 3 is good for general work. Can use whilst using a soldering iron and pliers without risking getting burn't. 5 for examination of a small item. 7 for looking at surface defects etc (I use mine for looking at solder bridges on surface mount devices). I do have the lenses for a size 10 magnification but that is just "silly" for most uses and I don't keep them installed in a visor. I wouldn't use a size 2 magnification for myself.....but there again I'm old and need bi-focals just to get around. My bi-focals close range work well for lathe work, so perhaps that might equate to a size 2 for other folks.
