Rusty,
I have used the Mag-Eyes for several years and I like them very much. They are around $30.00 and fit on your head and are very light. I have tried several of the other magnifiers that fit on the vise stem and like JC states, they are always in my way and I always bump them. Something else you can try, if you wear glasses, is ask you eye doctor to increase your bi-focal strength a little and that may be all you need. At my last eye check up I mentioned to my eye doctor that I tied flies and she increased the bi-focal a little and now I do not use the head mounted Mag-Eyes as much as I use too. Just my thoughts for what they are worth.

Fly fishing and fly tying are two things that I do, and when I am doing them, they are the only 2 things I think about. They clear my mind.
