Does anyone have any
experience with polarized lenses or filters in their shooting glasses??
I am
currently using a medium-tint, brown filter outdoors and am considering
experimenting with a polarized filter. I have trouble with the target being way
too bright and the sights being silhouetted instead being clear. I thought I'd
ask before I ordered.
regards,

According to Mr. Nygord a
.25 for indoor and .50 diopter lens for outdoor use will solve that. Also a
plain lens works best out side with yellow for inside. Hope that helps.

The brown tint is not
one of my personal favorites, I feel that is reduces the contrast on the target.
I prefer the grey tints and do use one pair of glasses with polarizing, if I
seem to be getting a lot of glare. With the rifle we used to shoot with the tint
and polarizing filters in the sight rather than on the glasses and I found that
worked very well under some conditions, and under other conditions I felt my
eyes were unshielded and I was trying to peer into a dark tunnel.

Even the folks that
supply glasses (Chammpion, Knobloch, etc.) aren't crazy about polarized lenses.
The problem: single polarized (one diffraction grating) will cut glare in one
direction - your choice. Dual polarized lenses can cut out total light, it's
true, but you pay a price: Either you have an incredibly heavy rig - 4 pieces of
good optical quality glass sandwiching two diffraction gratings, or you have
light but cheap and poor quality (distortion) pieces of plastic film in some
kind of holder. Actually, having your sights silhouetted in bright light isn't
really all that bad, sighting wise, if diffraction off the edges doesn't blur
them. Blackening the sights with soot helps this (see our "Black Match"
blackeners) and tends to keep the edges sharp. And, as another poster points
out, even in bright backround conditions, added power lenses will also mitigate
this condition somewhat. All glasses, sights, blackeners, etc. are a part of the
moving compromise with conditions, equipment and you! The more "tools" in your
bag, the better you can cope. Dedicate one of your training sessions on a bright
day to finding out what works best for you.
