If anyone can do it
www.sportsoptical.com probably can....
he does totally custom lenses, I don't know if he does bifocals, but I have a set of lenses made by him for my Smiths and they are teriffic. Everyone else told me no, my face is too small for wrap arounds, but he said no problem.
If he can't do it, your options probably go to prescription insert styles. I can't imagine why you could not do bifocals in those.
