Need info on Canon dioptric adjustment lenses, and, shooting with glasses on

    I'm pretty nearsighted, and my glasses are "no-line" progressives.
    I was at the store looking at cameras, and found that with my
    glasses off, none of the cameras' eyepiece diopter adjustment knobs
    went far enough minus to get me in focus.

    But with my glasses on, I'm kinda far away from the eyepiece, and
    after the best knob adjustment it still didn't look all that great,
    maybe because the glasses are progressive, which means the
    correction varies continuously from top to bottom.

    So I see that Amazon has "dioptric adjustment" lenses for $17, but
    it's not clear whether this is an additional lens that goes in front
    of the eyepiece, or a replacement for the existing eyepiece.

    Apparently the adjustment lens also requires something called a
    "rubber frame", but I can't tell if that's already on the camera, or
    has to be ordered as well.

    I've been looking at the XSi, and maybe a used XTi.

    Can someone who has been down this road share some information and
    wisdom with me? Also, do most people who seriously need glasses
    just shoot with their glasses on?

    The "rubber frame" around the eyepiece on the XTi is removable, so it's
    possible to replace it with a lens, that could itself receive the frame.

    Thanks for everyone's responses.
    I'm nearsighted enough that I see quite well close up
    without glasses, so with the right diopter adjustment for
    the eyepiece I could be in no-glasses mode for everything.
    Well, except for viewing the scene without the camera. :)
    I'll give that a try and see if I can make it work. It's
    just that for manual focusing situations I think it would be
    best to operate without the glasses. But I'll just have to
