Ray,
I use 2.5 power "Flip Focus" that are screwed to my hat. This works both
for fly tying at the bench and for fly tying on the water. They seem to
last 3-5 years before needing replacing.

Good luck
John

I have recently returned to fly tying but tempus fugit has made life
significantly more difficult even with glasses, I have tried using a
small flexible magnifying glass in front but have not found that very
satisfactory, suggestions please??
