Oakley's are out of consideration for you, and me. I wanted a pair of Jawbones or Flak Jacket XLJ's but they only go up to a +2 or -2. I'm a +3.5 and just got Rudy Project's. Some of the Rudy's go up to +6/-6. I would call
Sports Optical. They know what works in prescription sunglasses. Call them and review your prescription with them, they can tell you what pairs will work best for you.
I chose Rudy Project Horus frames and got two sets of RX swappable lenses. One is polarized brown for day to day use and the other is yellow for flat light and night riding. Both are single vision. I've done progressives in the past and I can't stand the distortion I get from the wrap.
