progressive lenses

[rx sunglasses]

I have been told that progressive lenses should only be ordered in person. That other measurements were required, in addition to the PD.
Can you offer any insight.

Thank you in advance.

It is essential that you provide the accurate segment height, B measurement in addition to PD measurement.As long as you can provide these measurements,i guess they can provide you a comfortable progressive glasses.
