Any optician can read the Rx from your glasses. No optician I know will make a pair of glasses from that read since he or she does not know if it is correct.
No optician I know would give an Rx over the phone to anyone other than another Eye Care Professional since if you wrote it down incorrectly, he or she would still be legally responsible for it.
Call the optometrist and have him mail it to you. 40 miles, should take two days at the most.
