You've gotten 2 bizarre answers, probably more to come.  Assuming the Rx
is indeed a CLRx (not a spectacle Rx that is "OK for contacts" type),
you can get the -11 (no more, and I'm amazed to see who suggested that
little tidbit), and then have the resudual measured while you are
wearing the contacts for the over-wear glasses.  The other "Dr." is just
wrong.  1.25 cyls just don't disappear, and the idea of ignoring it is a
bad one, if you're interested in sharp vision.

w.stacy, o.d.

I'm probably using the wrong terms, but hopefully you'll get my point.
If I have a contacts prescription of -11 sph, -1.25 cyl. What would
happen if I wore spherical contacts -11 and left the astigmatism
uncorrected? What would my "equivalent" vision be like?

The reason I'm asking is because they do not make disposable contacts
with my prescription, only custom-made torics. But they do have
spherical disposables at the same power. I'm just wondering if I could
see decently (everything except reading and driving) without correcting
astigmatism.
