Prescription difference between eyes

    Is it common for people to have issues with large differentials in
    prescription between the two eyes? I've been having some difficulty,
    and I wonder if it's possible that it's due to different cylinder
    correction. I only have a 0.5 difference (-1 vs -1.5) but the
    difference in distortion looks, subjectively, like kind of a lot if I
    look through the lenses without them on my face. Is it possible that I
    might be happier if I split the difference and used -1.25 on both eyes,
    even though things might not be as clear? In case it matters, I have
    0.25 difference in spherical as well (+0.25, -1 vs. PL, -1.5).

    Dear Charles,

    Why not discuss these issues with
    your optometrist?

    I think he would be willing to support
    what you request.

    Dear Charles,

    Please disregard Otis's postings. He is not in the medical profession, and
    not in any position to give medical advice.

    Thank you!

    My right eye is +3.5 and my left is +5.75 Been about that way as long as I
    can remember and I don't see why/how it causes trouble. What does cause
    problems, though, is my -2.25 astigmatism.

    Dear Charles,

    Subject: Brain dead Liberman.

    It would be nice if Allen actually
    READ what I posted.

    content and "advice".

    It was a "test" to see if Allen Liberman
    actually READS anything or
    just has this knee-jerk response
    to any post I might make.

    Half diopter difference shouldnt be noticable. Your optometrist gave
    you the right pescription, stick with it. Since your pescription is
    (very)low, your dependancy on glasses is low likewise. You do many
    things without glasses. My brother is -1.25 and doesnt need glasses
    except for driving.

    The axis of the astigmatism could be important here too.

    Ordinarily I wouldn't have thought a difference of 050 cyl would make
    that much difference - what are the difficulties you're having?

    You'd probably use 1.00 in each eye rather than the 1.25 compromise.

    Aceman how do you know "your dependancy on glasses is low" and "You do
    many things without glasses" to be the case?? For all you know he may
    wear glasses all the time. He may choose to do NO things without his
    glasses. He may feel uncomfortable without his glasses on. He may love
    wearing his glasses all of the time. We just don't know.

    However you are preaching to other people and telling them what they
    should be experiencing based on your (and your family's and friends')
    personal experiences. If you'd refrain from doing this you'd probably be
    a lot more popular on this newsgroup, as *sometimes* you do actually
    come up with some helpful advice.

    Actually, I passed the test. I got you to react. Now if I could get you
    to READ my questions and ANSWER MY QUESTIONS.

    Like I said earlier Otis, the content of your posts equate to zero, zilch,
    nada, nothing and I will be sure anybody you reply to knows that.

    Do you get it yet?

    Thanks for the replies. My issue is a subtle feeling of
    non-cooperation between my eyes even though they are both sharp
    individually, mostly at distance. I'm working it with vision therapy,
    which mostly atacks convergence trouble, but this was another theory I
    had. I mostly wanted to ask the professionals on the forum how common
    it is for people to have trouble with different Rx between eyes.

    As a data point, I wear my glasses almost all the time. I sometimes
    get my breakfast and do stuff in the morning without them, but I really
    can't stand to be outside without them. I can read without them, but
    it's somewhat annoying, especially a computer screen, since it's
    further away. I think the 0.25 difference in sphere power makes it
    kind of annoying to go between glasses and no glasses. I can do better
    without them first thing in the morning than in the evening after
    wearing them all day.

    The simple fact hes only -1 would put him in perfect focus at 1 meter
    which means glasses wont make a difference for reading or eating. The
    exception if the astigmastim is significent but I have .75 and 1.5
    astigmastim in my eyes and my .75 eye sees perfect at reading distance
    while the 1.5 astigmastim sees a little blurry but if I tilt my head, I
    can make horizontal or vertical lines clear. Perhaps he actually likes
    wearing glasses and/or is super picky about the tiniest bit of blur in
    the distance. I can not speak for him but the majority of my -1 friends
    go without glasses much or all of the time. They dont have any problem
    seeing and neither does my -1.25 brother. They dislike glasses so to
    them its worth seeing a tiny bit less clear in order to do away with
    the hassles of glasses. The very slight blur is less annoying than
    dealing with glasses accroding to my brother and friends. I would
    myself wear glasses much less when/if my vision improves so its down to
    a -2 to -2.5

    I'm not sure this is the right way to look at it with astigmatism. I'd
    agree for plain old nearsightedness.

    I'd say a subtle feeling of non-cooperation between the eyes is more
    likely due to a problem either with the alignment of the lenses in your
    glasses (rather than the prescription strength), or the co-ordination
    between your eyes (e.g. convergence etc). Just my opinion based on the
    words you've used to describe it.

    1. Who were you replying to? Your post was threaded as a reply to
    Charles but it reads like a reply to me.

    2. You wrote, "The simple fact hes only -1 would put him in perfect
    focus at 1 meter" - are we talking about the same person?? Charles tells
    us his eyes have cylinders of 1.00 and 1.50 respectively which
    definitely doesn't give him perfect focus at one metre, or at any
    distance for that matter. Surely all of your reading & research has
    given you a better understanding of astigmatism than that?

    3. You wrote, "glasses wont make a difference for reading or
    eating"....YES THEY WILL!!! Sure there are some people with similar
    amounts of astigmatism who may be happy to go without glasses some or
    all of the time, but let me assure you that there are plenty of other
    people, perhaps more discerning than you, your family, your friends &
    acquaintances, who find that glasses correcting a 1.00D cyl make a real
    difference to reading and other tasks.

    4. You wrote, "I can not speak for him but..." - well then why *do* you
    presume to speak for him, several times in this thread alone, not to
    mention in other threads? Your visual experiences are not necessarily
    the experiences of others.

    Well, that's what they think right now anyway. Like I said, I'm doing
    VT for it. Unfortunately, it hasn't been the miracle cure I hoped for,
    after 3 months... I'm always alert to other possibilities.
