The lenses are a plastic full back side progressive, configured for a minimum height of 16. They are mounted in semi-rimless groove frame 53:18 w/ a 33.5 B measurement.

monocular pd's 32/35 fit at a seg height of 22
After Rx verification I typically look to the fitting parameters for cause, ...... although the last time I went through this exercise it was ultimately resolved with a Rx change.
I would be appreciative to have comments from folks that also experienced this and feedback as to cause ...... thanks.
