    I have an O.D. who gave me an eye test and never left the 20/20 size line on
    the chart. For distance, one of my eyes is blurred with his prescription,
    relative to the other. Should I expect a prescription that gives me
    symmetrical vision quality for both eyes, if this is possible? If I can see
    the 20/20 line clearly with one eye, and struggle to guess correctly when
    using the other, do I see at least 20/20 in the second eye? Or is 20/20
    seeing clearly the 20/20 line?

    You should go back to the optometrist and voice your concern. He can verify
    that the glasses were made to the accurate prescription and re-check your

    I believe my optometrist has bad quality control methods, and wonder if he
    was taking a shortcut. The prescription he gave me he originally pulled
    from a previous pair of glasses I had. Then he gave me an exam, and later
    told me that the prescription had not changed. And it is this old
    prescription that he says is the same as the new prescription. He has
    rechecked my vision. But only to the 20/20 line on the chart. There is a
    longer story that I am not going to flesh out here that includes him not
    checking a new pair of glasses to see if a prescription was accurate, when
    this was clearly indicated. And after a lot of expense and time spent, he
    then checked, and discovered that a prescription was not accurate. But I
    only want the answer to my question as phrased, or an understanding that I
    may be missing.

    Dear Reece,

    You are presenting a mystery here.

    The standard approach is to place you in a chair and
    read the eye-chart through a "phoropter".

    The OD simply changes lens power (and astigmatism)
    until you read the 20/20 line. (None of this
    relies on any previous prescription -- I do not
    know why you state this as an issue.)

    If he can not bring your eyes "up" to 20/20 by this
    process -- he needs to explain that he could not do
    it, and attempt to find our why. At the very
    least, he needs to explain what he is doing.

    It is not clear what he might have said. I would
    return to him and ask him about this issue -- and
    he will work to satisfy you with 20/20 in both eyes
    as you request.

    If not, please post here and we will help you.

    There is a pair of glasses that I have to go back for that I paid for that
    is a factor in why I am asking these questions here. A new lens costs over
    $150. I will not use that optometrist in the future, rest assured of that.

    It is too bad you can't answer any of my original questions.

    Thanks Robert.

    No known pathologies or anomalies.
    Age: 48
    Single vision
    ___ sph cyl Axis
    od -3.50 -1.50 017
    os -3.50 -1.25 167

    I would have preferred my optometrist have gone to the 20/15 line to
    determine that my eyes were not corrected to vision of equal quality.

    So, with that information, what can we conclude? Should I have to specially
    ask to have equal quality of vision in both eyes? Or is merely ensuring
    that each eye is 20/20 corrected a job within standards, without regard to
    symmetry in vision quality?

    I'm no OD, but I know they like to start with the old prescription and
    move up and down until they get best vision. This is my preference. When
    I was a -10 I wouldn't have liked sitting in the chair while they started
    from -1 and worked their way up to -10. That would have been a waste of
    time for both of us.

    Thank you Robert! You have given me closure on the reason for my visit to
    this newsgroup. I will now be informed in my next conversation with that
    O.D. It is a tricky situation, as the O.D. is "independent" of a major
    glasses retailer and at the same site as well. And so, since they are not a
    single entity, it makes for a creepier transaction when things go wrong.

    My abbreviated history on a single pair of glasses is this:
    1. On first visit to this O.D., the Dr. looks at my glasses, does an exam,
    writes a prescription. And states that my vision has changed little. To me
    this means that my vision has changed, as he could not logically make this
    statement based on the old prescription obtained by looking at the glasses,
    if my prescription hadn't changed. (That is my opinion.)
    2. I go to another branch of the major glasses retailer, as it is near a
    project where I work. I immediately notice a blur in one eye. Salesperson
    says that it is probably because I am tired.
    3. The next day I just put on my new glasses, and indoors they seem fine. I
    am working heavy hours, so I don't do a lot of tests, and never put on my
    old glasses for months.
    4. Believing that my prescription has changed, albeit little, I go in to the
    retailer branch where the Dr. who wrote my prescription worked, to have new
    sunglasses ordered. But while they are ringing it up, I notice that my new
    glasses are blurry out of the same eye that was the case when I picked them
    up, and so I ask them to hold my order while I make an appt. with the Dr.
    that wrote the prescription. I told my Dr. about the blurriness and the
    blurriness when they were first delivered, and so he gave me an exam. I
    asked him if he didn't want to check glasses to get the prescription from
    the glasses to see if they were correct. He declined, assuring me that the
    were correct. He proceeded to examine my eyes, and based on his test, there
    was what he called an insignificant change in the prescription. Changing
    the Cyl. from -1.25 to -1.50. (I state these numbers from memory.) He
    insisted that it was insignificant. And handed me a lens to look through
    with my glasses. It clearly made a difference. Unbeknownst to me the
    correction was for the left eye, and I tested the lens with my right eye.
    (I had told him that it was my right eye that was seeing blurry.) So based
    on this, I had a new lens ordered for my glasses with the new prescription.
    5. The glasses came back, and of course the blur was still there, since the
    lens had been changed for the other eye (if that!). And so finally the Dr.
    looked at the glasses, and discovered that both lenses were incorrect. So
    right now I am fighting for the $160 on the bogus lens change with the
    retailer. But if it goes poorly there, I will fight with the O.D.'s

    Over the last few days I discovered that for distance, with my old glasses,
    it is blurry for reading at a distance through my right eye, suggesting to
    me that the same will be the case with my new glasses, whenever they call me
    to pick them up. Since my new prescription for the right eye hasn't
    changed, according to what the Dr. said. So I expect that the lab will have
    done it to match my old glasses on the right eye, which means, that although
    my right eye corrected sees 20/20, it is not close to being equal in
    corrected quality to my left eye. Which means there is yet another fight.
    So there is my story.

    Thanks again for your input. The knowledge I have gotten from your response
    and way you have discussed the issue will undoubtedly help me resolve this
    mess, in a low-key way.

    I will happiliy excuse you for 'trying to get information.' What I'm
    calling you on is being petulant toward people who were trying to help you
    in the best way they could. May I suggest a simple "Thanks," or, "Excellent
    suggestion, but do you also know whether equal vision in both eyes should be
    expected?" or even . . . no reply at all if you didn't get the info you
    wanted? The information you provided us in your original post--as it turns
    out--was inadequate to give you a very precise response.

    I don't mean to come across too strongly. This is e-mail and all tone is
    absent. I'm just suggesting that your response was a bit sarcastic and
    unnecessary . . . for future reference.

    That is fair. I will keep that in mind. Thanks for being a mirror to show
    me what I could not otherwise see.

    You are a gentleman and a scholar. Best of luck with your optometrist.
    Please let the newsgroup know how it turns out!

    Thanks, MT. I appreciate your response.

    How does an O.D. get both eyes balanced?

    Thank you very much for your detailed reply, Mike!

    In my case, I don't believe my Dr. did any balancing. But I think that your
    statement that closing one eye affects the posture of your focusing muscles
    is important in my case. And maybe that is my whole issue with my old
    glasses--which my new glasses that are being corrected will pretty much
    match. I have run tests on myself this afternoon, and I observed that
    sometimes I can read the 20/15 line with either eye (I printed a chart
    out)--especially if I focus using both first and then just cover one eye or
    the other (with a very bright light on the chart). It also seems to work
    better if I do not completely cover the eye that is not looking at the
    chart. This perfectly dovetails with the posture of my focusing muscles
    issue when closing an eye.

    On Saturday, I had a bit of trouble seeing text on distant signs clearly
    with my left eye when I was driving, compared to my right eye, using the
    cover-an-eye method. So, perhaps my left eye knows how to posture solo
    better than my right. My right eye has lived with an astigmatism correction
    that was off by 6 degrees from May to September, so perhaps it got lazy (if
    eyes can get lazy that way).

    So I will pick up my glasses on the morning after they call me, when my eyes
    are fresh and the sun is out, and will focus with both eyes when I go
    outside of the place, and then close one eye or the other for testing on
    distant signs.

    Thanks again!
