These gentleman who owns the store (whose name escapes me) was great to work with. Advice - call and talk to him. You get a better price on the phone than on-line.

My $0.02 - I now fly with dark polarized lenses in all but the flattest light. After going back and forth between the non-polarized Sun Tigers and the polarized dark (mirrored) lenses, I settled on the polarized dark glasses.

Both are prescription glasses with variable bi-focal lenses.

I always carry the Sun Tigers to the field "just in case".
