Having not been in this business in the days of huge frames, I really don't know what the correct thing to do with a large seg height is.
Had a patient in today. She wants to keep her 20 year old frame with a measured PAL seg height of 28, this is her first bifocal, with a lower add (+1.00 I think) Sure, sure, some of you have fit larger heights than this! :D
Do I use a newer lens with minimum fitting height of 18 or so, or an older design with a larger minimum? Will it make any significant difference?
Thanks!
