Paul, you've go it right, I think. That "center" of something has to be ground into the lense in the right place. I do think one does have to learn to move one's head up and down, right to left, rather than the eyes. Can you imagine the scene I created when this 'optic fitter" told me I would get used to the electrical outlet on the wall being in the wrong place in 2 weeks. If they're fit right you can walk out the door with no problems. I wouldn't have known that if I hadn't had them correctly fitted before. Just like a miracle. NOW, I WISH PD MEDS WORKED LIKE THAT FOR ME. Thanks and good vision to all.
