Has anybody ordered these in a higher prescription? I'm a -3.75 so was wondering if there was any distortion at all in the wrap models.

I don't know whether LIP can offer you a prescription for -3.75, but I can tell you that Silverfish have supplied me with prescription sunnies in the past.... once single focals and once multi-focals... and I've been very happy with them... PLUS they were less expensive than the LIP quote. So when you're checking out quotes... Silverfish is another option.
