    I just a new pair of glasses with hi-index multi-coated polycarbonate
    lenses. When I look at my computer screen, the center bulges out
    towards me and when I look at the floor below me, it seems to curve
    upwards to the front. I have no such problems with my old glasses. My
    optician tells me that it is because of the new frame which is more
    curved(wraparound) than my previous one. He says that my brain will
    compensate for it eventually. I have been wearing them for a week
    without any change in the distortion. What should I do?

    P.S This is a new optician for me.

    possibly you've had a prescription change (change in astigmatism or
    significant increase lens power in one eye). such changes readily
    cause a temporary change in spatial perception which passes as you
    become adjusted to the new proper prescription.

    if you really have been wearing the glasses for a week, and are not
    periodically going back to your old pair (important!!. you will have
    trouble adjusting if you keep going back to your old specs), then I
    would take them back to where you got them to have things checked out.
    possible they are made inproperly or the original prescription is off.

    This could be due to an excessive astigmatism "correction".

    You could ask the new optician if you could have the
    "astigmatism-cut" reduced.

    Or just go back to your previous prescription.

    He had increased the astigmatism correction initially but had cut it
    back to my original prescription after I complained about the
    distortion. However, even with this new pair of lenses, the problem

  5. Polycarbonate eyeglass lenses have been around for about thirty years,
    and every few years they seem to get a little better. While that is a
    good thing, the bottom line is that the old standard for superior
    vision is CR-39. When a patient is sensitive to perpheral distortion,
    and has worn a pair of well-made good old fashioned CR-39 lenses, he
    virtually always hates his new poly lenses. The good news about poly
    is that you can shoot it with a 22mm caliber bullet and it won't
    shatter. It has been the material that airplane windows are made of
    for decades. But...just think about it....have you ever looked out an
    airplane window what didn't drop off in quality as you looked out
    towards the edge? Enough said.

  6. P.S. Poly lenses and high index lenses are often cut on flatter
    front-surface curves, to hide the thickness of the lens. Sometimes the
    flatness of the lens will bother you more than just the poly. You need
    an optician who studies and solves problems so you don't have to.

    Please disregard Otis's postings.

    He is not in the medical profession nor in any position to give medical
    advice such as above.

    Thank you!

    High index has chromatic distortions. If you arent vain about the
    slight increase in thickness, you dont need high index, especially if
    your prescription is below -10.
