I have no experiance at all with added diopterglas to a camera.
I am also wearing glasses for some 40 years, and in the last few years i also need reading glasses, or take my glasses off when reading. (reading just with my right eye, my right eye is only +0.5, left eye is +2.25).
But with the K7 i am missing a lot of very good manual shot because they are sligtly of out of focus. so i was wondering of an added diopterglass would improve my shooting. Putting my glasses on and of isn't really a handicap because i would only take pictures without my glasses in special circumstances like makro shooting.
But when you would have to take the added glas on and off of you're camera it really would be a handicap. So that is the reason i wonder if you can add diopter classes so you could set it with the diopter slider when taking makro shots without you're glasses.
I also take my glasses off to read, in and also when working on the computer, but I guess I am young enough (i'll leave that debate for another time)
that my correct reading perscription is still somewhat negative in diopter, so that is a significant difference between our situations, and a slip on diopter may be appropriate, but I am not sure where you can get one.
I had one for my old Ricoh XR-2s which was actually a canon part, I am not sure what attachments are made for newer pentax cameras, but here is another idea.
What about a viewfinder magnifier, for the macro work. I have for example, a rignt angle viewfinder that has it's own built in diopter adjustment in addition to the viewfinder, and that I do use without my glasses when doing copy work, and adjusted to my natural eyesight without glasses.
I know there are some who use an eyepeice enlarger, so maybe they can chime in, In that case, set the camera for your glasses, and the eyepeice magnifier for the difference
