It certainly depends on the results you're after. If you're photographing landscapes you're not worried about "missing something", and taking lots of pictures without manual adjustments won't do any good.
I thought the diopter adjustment could compensate for glasses?

The problem I had when I tried it was that I could get everything looking perfect through the viewfinder, but the resulting picture was blurred. My current prescriptions round to the nearest 0.25 (glasses) / 0.5 (contacts) dioptres.
Even if I could make a perfect adjustment, my vision alters during the day. For example when tired things can get a little blurry.
