Owlie, I purchased Oakley wrap prescription glasses on line, possible because of a digital lens making technique ... but they were very expensive ($400). I'm sure you don't need bifocal lenses, which would make it cheaper. I could only do it because I had $ in a flexible spending account.
PM me if you want more info.
Another solution is to buy the sunglasses that take prescription inserts. (Performance has some of those).
I hope that's helpful
