I use progressive lenses for normal day wear and for flying airplanes.
I usually use suntigers with stick on reading lenses in the sailplane
but sometimes fly with the progressives. The only problem is that they
do not darken enough. My next set of suntigers will be progressive. My
first reaction to progressives was that it would be impossible to fly
with them. I may have had a bad prescription because after suffering
with line bifocals for a few years I went to progressives and will not
go back.

What good reasons do you gave against using them?
