jeffro,
In the beginning of my fly tying I tried to use the "swing arm lighted ones" and, like you, found them to be constantly in my way and finally settled on the "Mageyes" headset type and they really do make a difference in the quality of the finished product. I also have the ones that fit on your glasses and they work well too. At the present time, I do not use any type of magnification when tying. This is due to my last eye exam and the eye doctor and I were discussing my addiction to fly tying and fishing. When I got my new glasses I noticed that I did not need the magnification when tying. I called my eye doctor and asked if they had done something different with my new glasses and they told me that they had "bumped" up the bi-focal on my glasses by a small percentage and told me that if that gave me any problems, to let them know. To this day, I have had no problems. I seldom use any addictional magnification, but, will sometimes when tying something very small.

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.
