frank500,
I have been very happy with the progressive lenses, rather than bi- or trifocals. Discovered when I finally had to get glasses that allowed me both to hunt and read 20 years ago that tilting my head a little bit with the progressives could put that final clear touch on the front sight, whether with handguns or rifles.
I have also found progressive lens make using a computer easier than bi-focals. It doesn’t take much practice in my experience to find the sweet spot that for me doesn’t exist bi-focal lens.
