Help! What's the exact name of these sunglasses.?

I think www.replacementlensexpress.com might be a good place to start. They do lots of custom prescription lenses, or just sunglass tints, and prices are pretty low. As for the frames, they don't show them on their site, but if you e-mail them at info@replacementlensexpress.com they can probably do a search. Maybe if you attach a photo to your e-mail that would help too.
