I have the Wiley-X Airborne with progressive RX lens both clear and sunglasses. At first I did not like them as the curve of the lens created a vision distortion. After wearing them for a few days my brain corrected and totally love them. I also had to get used to progressives as I had only worn bifocals. No I can switch back and forth without issues.

 

I have the Wiley Bricks with dark gray lenses and a pair of bobsters with clear lenses, both with single vision scripts from Rx Safety. Both are great and I got the two pair because I didn't trust that the transitions would get dark enough. From the comments here, I'm glad I did, because I like a dark glass for riding in the sun. Distortion was bad because of the lens curvature but the brain adjusts after a bit, and I wear them everyday now. I got the polarized lens, too...

 

I had them put extra tint on mine though it was "extra" as well.
