    Dear Ladies and Gentlemen:

    I hope you can provide some advice, and thank you, in advance...

    My age is 46. Some six years ago, I suffered a corneal ulcer in my right eye
    and my vision has not been able to be corrected to 20/20 since then (this
    particularly sucks, as I had been a commercial pilot until then).

    Prior to the ulcer, I had single vision correction (both for glasses, as
    well as contacts):

    -1.75 Left
    -0.75 Right

    Shortly after the ulcer healed, the ophthalmologist adjusted my prescription

    -1.75 Left
    0.00 Right

    After lengthy refractions, it was determined that my right eye saw best with
    no power, either way. I was comfortable with my contacts and glasses, with
    that prescription.

    Now, well into my 40's, I recently went for a contact lens-exam and was
    given a +2.25 for my right eye -- it has been great! I seldom have to wear

    Two months ago, I decided to get new eye-glass frames. This is when my
    problems really began: my new eyeglasses are polycarb, and very, very

    The optometrist scoffed at my inquiry to make the right lens a +2.25, to
    mimic my contact lens prescription. He said that a one-lens contact
    "farsighted" prescription cannot be carried over to one lens in a pair of

    Please: is this true???

    If I'm seeing well with -1.75 and +2.25 while wearing contacts, why couldn't
    I have glasses built with those respective powers?

    My insurance company is willing to "allow" me to swap the polycarbs for
    Trivex -- will this help at all?

    And what about Crizal Alize? And edge-polishing?

    Sorry for the myriad of questions.

    Quite confused,

    Tammy, you have 4 diopters of anisometropia (ie. refractive
    difference between your 2 eyes) when you are wearing your
    monovision contact lenses. While this difference (between
    your two eyes) works with contact lenses, it does not
    work as well with glasses (image size differences). I
    guess you could try it if the doc agrees to the rx but it's
    more than a good possibility than you would have some
    difficulty getting adapted to it. I have fit patients in
    "monovision" glasses (but it's not common) but the
    difference is usually much less than in your situation.

    As far as the polycarbs, just about any type of lens
    (Crizals/Trivex) would give you better clarity).

    Hope this helps.

    Dear Dr. Frank,

    Thank you for your response to my inquiry! Are you saying that you HAVE had
    positive feedback from those who asked for "monovision" glasses?I think that I read somewhere on this newsgroup that Crizal's Alize is not
    available to Trivex material. Am really curious as to that, since, after
    speaking with my insurer, I was led to believe that Crizal Alize is an
    option that they would cover. (But do they realize that Crizal Alize might
    not be available as a coating on Trivex lenses?)

    Again, thanks in advance, to all!

    I have a few patients doing both monovision with cl's and glasses but
    they are in the minority and with much less than the 4 diopters
    of difference than what you have. Without actually trying it for you
    I couldn't predict how well you would do.
    Tammy, even a regular cr-39 (regular plastic) would be suitable
    for you. I don't have the information in front of me so I'm not sure
    whether the Alize is available on Tivex. Your optician could tell
    you for sure. Best of luck.

    Thanks again, Dr. Frank, for your comments!

    My optometrist said he suggests polycarbs for semi-rimless frames, as the
    lens thickness-variance between the two sides would not be as noticeable.
    Would the cr-39 lenses (-2.00
    and 0.00
    ) be so awkward-looking
    together, in a rimless frame?

    BTW, I made it very clear to my optometrist that vision acuity was of
    import; that a negligible difference in thickness between the two lenses
    mattered far less, as I would be wearing the glasses at home, at night,

    Thank you so much for your perceptiveness and professionalism!
