As a lifelong eyeglass wearer, for shooting arms and archery, I myself
gave up on wearing progressive lenses
. The optimum optical center is far TOO SMALL/NARROW and if one's stance and/or form means that their head is not pointed
exactly and
directly straight-on to the intended target ... the image is blurry! Am glad that others have success with progs ... but I haven't (
at least since I've aged ...).
I had a pair of the
old-fashioned typical bifocals made up expressly for shooting glasses and now I can see the front sight clearly, where ALL your focus should be. At the last woodwalk I attended I won everything, perfect socres on the woodswalk, smallest group (attached) and all X's on the highest score target.
Now I can see! My goal is to now beat that rifle 'smallest group' target, shot offhand for 5-shots @ 30-yards. That's with a 'coned' muzzle to boot!
Actually I think I'll raise that goal ... as I still think that the 50-yard offhand, flintlock smoothbore (NO rear signt!) target as shot (nd witnessed) by the late Tip Curtis where the 5-shots formed one ragged hole centered right in the X ...
is the epitome of muzzleloading shooting!
