Yep, I got the Dual FL1 (now discontinued), their lowest priced bifocal sunglasses, almost exactly a year ago. They're fine, no problems. I'd consider getting another pair, if they made some without a frame over the brow. The Dual FL1 doesn't hinder my view.
I was generally satisfied with low priced
Radians bifocals for only $10, but the frame over the brow blocked my view slightly when I was in the drops. The Dual FL1 had no frame over the brow of the lens, so it's better suited for my road bike rides. I still wear the Radians clear and sunglass bifocals on my hybrid -- no problems with the frame hindering my view.
