Excuse the elementary question. If I don't ask I don't know right and I'm a self motivated Optician to learn all I can in this career.
Do the lengths of the what I call corridor of Progressives change depending on the B measurement of the frame?
I had a lady that wanted a really big and deep frame this time. She liked a Ray Ban...RB7066 in eye 54 withB measure 44.2 I used a Varilux Comfort 2 Drx. At dispense the distance was fine but reading and intermediate she wasn't happy with. If she lifted the frame up and looked in the very bottom it was okbut just normal posture that wasn't going to work without holding theframe. Seg ht used was a 30.
She wanted to try PALs again as she's never been able to wear them without issues (and she could bejust one of those people who will never be able to adapt to them)She's even had smaller frames that weren't as deep and still had problems finding her reading areas. She was determined on getting a deeper frame this time.
After thinking or overthinking about it maybe, after I while I was curious how the PAL was going to bepositioned in such a deep frame, her eyes were more towards the topof the frame. I even asked my coworker about it and he seemed tothink it would be fine. And then come dispense day she's lifting the frame.
So does PAL length change according to depth of frameor all PAL corridor lengths in a way stationary they just shift according to seg where they'll be positioned. Hopefully I'm conveyingmy question the way I see it in my head lol Thanks!
