Twenty years ago, I had a beloved M-Frame that wasn't a prescription. I fell in love with the visor-style glasses and when my eyesight got bad enough that I had to get prescription sunglasses, I was relegated to either wire or fat plastic frames. I usually order direct from Oakley's government site, which doesn't have the Radar Path available. Now that I have these from Sunberry, I'm once again in my comfort zone.
The caveat is that the prescription lenses are somehow fused to the black polarized lens. There is a definite raised portion on both the front and inside. I guess there's no other way around it, but it looks a bit off. I think they look like stormtrooper shades. The result is blurry peripheral vision, which is also a slightly cooler tint. However, after wearing them for a few minutes, I hardly notice it. I knocked off a full star for this reason, but if half-stars were possible, I'd give it 4.5.
