So, an update for this saga. I went to the eye doctor today, and she checked my prescription, and the glasses, and then had me see the optician do some measurements also. It turns out the "bifocal" part started far too high up on the lens, so I called Goggle4u.com. They said to email them, and they would make me replacement glasses, and to give them the new measurements that they took today for Pupillary distance near AND distance, and for the segment height. I will let you know when I get them if they work!

The optician said, "I know you probably saved a bunch of money, but with prescriptions like yours, we see this kind of issue all the time when people order online." But he didn't yell at me, belittle me, or try to convince me to buy a more expensive pair from him, which I respect. He just gave me the measurements, bent the pair I was sent to be as good as he could get them, and sent me on my way.
