My local place can make custom clip on sunglasses for any frames, so you can always go that route. I got them for my old Cutler & Gross frames, and they're great, and a lot cheaper than I expected at $60. Custom made to fit the frame, you can pick the color of the lens and the frame to match your existing frames. Here's a picture for reference, in my volunteering-at-my-kid's-kindergarten steez.
