bad perscription and big frames

    I just got a new pair of perscription sunglasses. I purchased the Ray
    Ban Wayfarers, which are a quite large plastic frame. I noticed when I
    put them on that everything was a little distorted, especially on the
    sides. I felt taller and had weird depth perception, almost a
    "fisheye" effect.

    Is this a natural thing to happen with a really bad
    perscription/astigmatism and large lenses? I can see find when I look
    straight, everything just looks a little off on the sides. It isn't
    such a big deal, but is there anyway to remedy this or should I just
    adjust to it?

    Thanks for everyones' help,
    Alex

    Dear Alex,

    You might be over-prescribed for astigmatism.

    Perhaps you could ask them to reduce the amount of
    astigmatism, consistent with passing the 20/20 to 20/30 line.

    Best,

    Otis

    I don't think that is it. I have glasses (smaller frame) with the same
    perscription and those feel fine.
    Regards,
    Alex

    I think that's probably it Mike.

    Is it also possible that the optician "fit" the lens wrong. I remember
    she put a little machine up to my face and looked through it, I assume
    to take measurements. Could the focal point be off. I notice that
    when i hold the glasses higher on my face, so my eyes look through the
    bottom, I get less distortion.

  5. I think you mean "high" prescription, not "bad" which would indicate
    "wrong" Rx.

    Anyway, a large wrap around frame requires you to look at an angle
    different from the normal perpindicular angle, which changes your
    "effective" Rx. Some labs can correct for that (and some docs can too),
    but certainly not all are even aware of this problem. The Rx needs to
    be adjusted for the degree of "wrap", or you need to select a more
    "normal" frame.

    w.stacy, o.d.

    p.s. you may laugh at ol' otis' posts, but do not question them...

    Dear Alex,

    You have a lot on info to go on, but be sure that the base curve of the
    lenses, both old and new, are matched because it will affect the image
    that you percieve.

    LOL.. I'm guessing some people in the states say it "perscription"..
    we see it often and it is so funny.
