[Leica] Changing eyes, M focusing

[matthew at hunt.tc (Matthew Hunt)]

I wore the coating off my varifocals on the upper left corner of the right
eyeglass in about 4 months after getting the M8.  I too had noticed some
near focus problems but didn't think it could be the glasses, so will try
your technique.  I am 47 and have had varifocals for 2 years, they are by
Zeiss and I got to use them very easily.  I use the viewfinder magnifier
quite a lot now.

Dear Peter,

It comes to us all!  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!
