    I read somewhere that it takes several days for one to get used to the
    cylindar component of glasses. My glasses came in today

    left eye: -4.5 sphere, -.75 cylindar(140 axis) correctable to 20/30
    right eye: -3.5 sphere, -1.5 cylindar(55 axis) correctable to 20/40


    When I put them on, instantly I could tell something was wrong. The
    right eye experienced blurring, doubling and smearing. Soon, my eyes
    begin feeling strained and my pseudomyopia got half a diopter worse.
    The left eye sees fairly much fine but not the right eye. I have never
    had this much cylindar before. The optometrists went higher on the
    sphere and lower on the cylindar. I also have irregular astigmastim and
    high order aberrations so anything done will just be an approximation.
    Going higher on the sphere does reduce the smearing and doubling but
    causes a strange type of blur where letters look thick and bold. The
    -1.5 cylindar causes strange disortions as well, especially when I tilt
    my head, shapes change. I am much happier with my old glasses which
    just ignored the cylindar. Yes I can see better on an eyechart with the
    cylindar corrected but the quality of vision is poor(hint, hint for
    those considering lasik!) Right now im seeing 20/80 or so with those
    -3.25 glasses but the quality of vision is better and my eyes dont feel
    strained vs. my new glasses which give me 20/30 in one eye, 20/40 in
    the other(my bcva) Should I just suck up and give some time to get used
    to the new glasses?

    Go back to your OD and explain your problem. It should not take any time to
    adapt to SV lenses.

    Maybe you've messed up your eyes with all those eye exercises and you've
    made them even harder to correct.

  4. Your "irregular astigmatism" sounds like it was surgically induced by
    your LASIK, and the astigmatism correction you have with your head
    turned to one position can be different when you turn your head to
    another position. RGP contacts would be a much better corrective
    device. The newest wavefront spectacles might also eliminate your
    "barrel distortion" but they are available in limited areas and only
    from opticians who buy into a wavefront refraction system.

    I disagree because I see fine with my -3.25 glasses. My eyes feel
    relaxed and seeing isnt an effort. With my new glasses my eyes feel
    strained, especially the right eye. Maybe it has to do with my
    irregular astigmastim which shouldnt attempted to be corrected with
    glasses, but instead just left alone? I have adapted fine to every
    glasses except this one with the -1.5 cylindar. The left eye with -.75
    is doing quite well.

    The same thought immediately came to mind. Then my
    second thought was that maybe he should have purchased
    a system instead of following the free one...

    The thing is I never had lasik nor any surguries of any type. Here are
    my topographies I got last year. As you can see, the OD has an
    irregular bowtie shape. The OS has a rather regular and slight
    cylindar. Theres very little disortion in the OS, but the OD is much
    worse and I correct a line less than the OS. It would cost me $1500+ to
    give RGP(z-wave) contacts a try and no idea if ill be able to tolerate
    them. I can get new glasses and consider the glasses I have a loss(can
    save the frames) and see if they are better. I can either omit the
    cylindar or reduce it.

    Congratulations Ace! I think you have proven that NVI induces irregular
    astigmatism. Perhaps this is your legacy in the ophthalmologic world.

    Irregular astigmatism is present when the different meridians of
    curvature of the cornea are not 180 degrees apart or the cornea takes
    on multiple meridians of curvature. This condition may be thought of as
    a bumpy surface topography. The visual result of irregular astigmatism
    is distortion of vision that may not correct well even with glasses or
    contact lenses.

    I also learned more here:

    http://www.lasikinistanbul.com/eng/astigmatism.htm


    I dont see as blurry as the picture of the persons face but this gives
    an idea.

    "Astigmatism in which different parts of the same meridian have
    different degrees of curvature."

    I looked this up. Looking at my topographies, it makes sense. While the
    meridian is 180 degrees or parrallel, it is not symetrical. The lower
    half of the meridian has higher curvature than the upper half. My
    glasses which DONT correct any astigmastim at all doesnt give
    headaches. Attempting to correct my irregular astigmastim best as
    possible gets my BCVA to 20/40(sometimes can see some of 20/30) but
    with poor visual quality. Now I fully understand how people with bad
    lasik results feel! I prefer my 20/80 without the astigmastim
    correction over my 20/40 with!

    false, my topographies that showed irregular astigmastim was before
    NVI. When I did NVI, it reduced my myopia without changing anything
    else!

    Oh well. Perhaps you'll make a contribution some other time.

    update: I tried the glasses again. The one with the cylindar makes
    things from near MORE blurry than without cylindar. I can assume I may
    need a different cylindar and axis from near. Ah well I normally take
    my glasses off for reading anyway. I get strange disortions with the
    -1.5 cylindar correction in the right eye. The shape of things get
    disorted when I put the glasses on and when I walk around around,
    things are constantly disorting such as rectangles become more squarish
    or squares take on a rectangle appearance. Circles likewise become more
    oval. I also am experiencing anisometropia of 1 diopter sphere and .75
    diopters cylindar between the right and left eye. This instantly causes
    eyestrain and makes me feel dizzy and I have to struggle to fuse
    binocularity or my eyes wander. Its a vision quality issue, I am not
    worried about snellen accuracy. I have no problems with my old glasses
    which only correct the sphere and the same for both eyes, thereby
    avoiding any anisometropia. I will lose some snellen accuracy by
    omitting the cylindar but it avoids all the quality problems.

    Yeah, several days.

    Yes. Several days.

    Hi again, its been several days and I still cant get used to them. I
    wore the new glasses for watching a movie and my eyes hurt afterwards
    and I got a headach! I think I am going to have to order new glasses,
    ill get one pair that will correct less than the full amount of
    cylindar and one pair that ignores my cylindar alltogether. I wont
    achieve BCVA but comfort and NOT getting headaches is what matters. I
    will see what the optometrist says. I will ask him and you guys here
    about two other possible options:


    left eye: -4.5 sphere(will give me 20/40 by ignoring -.75 cylindar)
    right eye: -3.75 sphere(will give me 20/60 by ignoring -1.5 cylindar,
    but add -.25 more sphere. In fact I have a pair of glasses with -3.75
    for both so I know)


    left eye: -4.25 sphere(will give me 20/50 slight undercorrection In
    fact I have a pair of glasses with -4.25 for both so I know)
    right eye: -3.75 sphere(will give me 20/60 by ignoring -1.5 cylindar,
    but add -.25 more sphere)


    left eye: -4.25 sphere, -.5 cylindar(will give me 20/40 one line
    undercorrect)
    right eye: -3.75 sphere, -.5 cylindar(will give me 20/50 one line
    undercorrect)


    my ophthamologist said some of his patients prefer to wear their old
    glasses or be undercorrected because full power strains their eyes and
    gives headaches. Same problem for me. The astigmastim correction really
    bugs me though! To be honest, I dont think I ever had glasses with more
    than -.5 cylindar in them. The optometrist always seemed to go for
    spherical equivalent. Maybe this is what me and my eyes preferred even
    though my visual accuracy is equal or better by properly refracting my
    cylindar. I can see perfect(20/30 bcva) with a -5 spherical equivalent
    in the left eye. The right eye sees worse with a spherical equivalent
    cause I have too much cylindar. -4.25 is its spherical equivalent and
    it gives me 20/50.

    I will give my new glasses a little more time, but my eyes arent happy
    with them. visual accuracy isnt the problem, eyestrain and headaches
    are. Maybe my eyes will change/improve durning that time. I wear my
    -3.25 OU glasses most of the time. Great for intermediate but a little
    blurry for distance at 20/80 in the better eye.

    Ace doesn't drive. Ace doesn't have a car or job
    to drive to. Ace lives in a room in his folks house
    and only needs to see 32 to 40 inches in front of
    him.

    I dont drive nor care to. My vision is another excuse. Yes I can pass
    the DMV with my new glasses but I would not be safe driving with
    glasses that give me eye strain, headache and make me dizzy. I have a
    job now and will work my way up.

    so back on topic, what pescription should me and my optometrist agree
    on? I showed you several examples above
