Ah, I see I didn't indicate my problem clearly enough. The optics are actually quite excellent. It's the physical fitting of these particular frames that hurts—the work that the optician normally does after they come in from having the lenses put in. Bending the frames and whatnot until they actually fit my face.
As of now, I've isolated the pain to chafing at my left ear, and as with my previous glasses, I'll likely just live with it until I adapt. :P
So far, I'm actually satisfied, especially as I have conversations with people and am reminded how much glasses normally cost. Everything from $150-$400! And more, I'm sure.
As for pupillary distance, I had my optometrist do that during the exam. He did it quite cheerfully and assumed I was buying glasses online. Nice guy. He also even measured my existing glasses for sizing reference.
