I want to order my new glasses from zenni optical but I have a problem

The jerk that handles the pupil measurements and eye glasses across from my eye doctor wouldn't measure my pupils for me. told me "it's not my problem" even though my doctor requested he do it. (the dr's office and the optique are affiliated)

so I don't know what my pupil measurement is

is there ANYWAY I can do this myself? or no.

I'm so frustrated with lenscrafters and BJ's I'd rather not have to go to them
