Don't know how much custom ground lenses will run, but you could put
that toward an OM-3 or 4 series camera. They have built in diopter
adjustment to -3. Combine this with a -5 eyecup and you have a combo
that allows some adjustment around your -7 goal.
I'm about a -5 in my viewfinder eye, but just wear my glasses when
looking through the viewfinder. I use 'Pentax AF Progressive'
lenses,which are far, far superior to (and more expensive than!) regular
progressives and that may contribute to ease of use with a camera.

Susan,
I appreciate your insights, for those of us with less than perfect
sight. I've been trying to figure out a way to use my OM with Eyecup 1
and a correction lens.
AFAIK, the OM system only offered correction to -5 diopters. I tried
stacking a -5 and a -2 (sigh). This "worked", but the resulting stack
was too thick to allow the retainer to thread back on. Do you know of a
place that can grind an extreme prescription (about -7.5), and can these
use glass that will be thin enough to actually fit into eyecup 1?
Or, should I give up and go LASIK?
