RGP impact on astigmatism

    I've been wearing RGP for a while now. My glasses prescription is/was
    basically all 0/180 astigmatism in both eyes, about 1D. Vision with
    the contacts in is better in my right eye than my left. Comparing with
    friends, I think my right eye vision is better than average, but my
    left is slightly below. I notice a significant difference when
    indoors, but not really any outside in the sun.

    Another thing I've noticed is that with my contacts out I'm getting
    significant "ortho-k effect" such that I normally go the weekend
    without the lenses. I mostly only find my uncorrected vision
    objectionable in dimly lit situations and when driving. Anyway, on my
    left eye, it seems like my uncorrected astigmatism has rotated 90
    degrees. Where the blurring was up/down before, it seems left/right
    instead. It's very noticeable reading white on black text on the
    computer. If I look at something like an LED in a dark room, I do see
    some vertical blurring, but also a left/right doubling - the double is
    very close to the real thing, such that the LED needs to be small for
    them to be distinct.

    I'm going back to see my optometrist next week, but I was wondering if
    what I've described indicates what the best route might be to fine tune
    the left lens?
