Non-polarized, tough frames...look like they should work well, but do they always have 2 authors?

I buy $8 cheap shades at the 7-11; use and abuse as needed, and when broken or lost, as they inevitably are, no big deal.
And yes, even the cheap ones block UV, which isn't an issue in the cockpit anyhow, as aircraft windows already block UV.

Cockpit windows block UV-B. UV-A rays, still come thru, and is a reason that I use sunblock in the cockpit, for both UV-A and UV-B
