I went from no specs to specs for reading and then to specs for reading and another set for distance. For some time I just used no specs for the M because if I had the distance ones on I could not see the controls easily and glasses played havoc with the wide angle frames. Then I got variofocals, they took a while to get used to but now I wear them most of the time. I have no problem with the M, though I have more or less to guess where the 28mm frames are. It's life and there is no going back!
