OT...
Thunder and RedRockin,
Thanks for the ideas/links. My so-so experience with prescription sunglasses over the past 40 years is not the frames/fit but the seeming decline in lens quality by the "lens houses" doing the crafting for any of the optics joints: considerable distortion, lenses that pop out of frames, delamination of lens coating(s), etc.

Not trying to sound like some old hard to please finicky geezer, but my 20+ year old big lens, Aviator style sun glasses still work the best, even if they look stupid and the prescription is way out of date, as that lens quality was excellent...but, I will keep looking and try to replace my current newish, crummy pairs. Style ain't the deal for me; I want dark lenses that are distortion free and that "work".
Thanks, mD
