    Hi,
    I underwent strabismus surgery in my childhood, but doctors didn't
    take care of my fusion
    and stereopsis development, so I don't have normal binocular vison
    almost all my life.
    I'm able to "switch" my eyes, and when I look by one of them then the
    other deviate
    outwards. My doc says that I have an subjective strabismus angle, but
    objective angle
    is zero. When I look at an more distant object (lets say more than few
    meters away) I'm able
    to use both eyes, without any unpleasant sensations. But reading and
    using computer is a
    pain. It had become almost unbearable almost year ago, after I got job
    that require sitting in front
    of computer screen for 8 hours daily. After few months I started to
    feel weird sensations in my
    eyes. When I try to read, my right eye tends to deviate outward, and
    if i try to use both eyes
    then I cant see text clearly and feel that my eyes become somewhat
    uncoordinated. I get tired
    quickly and sometimes get headaches. Im going to see doctor soon but
    Im interested in your
    opinions: is this possible to don't have normal binocular vision and
    despite that be able to read
    without any problems ?
    Best Regards

    Neither my wife nor I have normal binocular vision and we see just fine.
    I have scar tissue in my right eye, and my wife has severe amblyopia in
    her right eye. We can read and use the computer as well as anyone else.
    There is a lack of eye-hand coordination, but we are used to that.

    I have a simple and cheap solution for you to try. Buy an eye patch.
    You can get them at any drug store. If it works, great. If not, toss
    it. They are very cheap.

    Welcome to The Club. I had the strabismus surgery at age 2,
    then again at 25. I'm now 47. Prescription is around -19.0
    I've been reading a book every two weeks since I was in highschool
    without any problems at all. For the past 20 years, I've also
    been on the computer 8 hours per weekday.

    About a month ago, I had cataract surgery on my non-dominant eye,
    and can stiil read and use the computer for hours without
    problems.

    I'm an engineer, not a doctor, but my guess is that your dominant eye
    is not as dominant as mine. I think the other poster's suggestion of
    using an eyepatch mught help.

  4. If your subjective and objective angles do not match, then you may have ARC
    (abnormal retinal correspondence), where the brain has adapted to an angle,
    and has decided to make a part of the retina that is not the "zero" location
    (the fovea) the new "zero". This actually does not happen at the level of
    the retina, but is a cortical brain adaptation. Not much to do about that.

    Most people who have had strabismus do not have normal binocular vision,
    which may be the reason they developed strabismus in the first place, due to
    abnormal fusion and abnormal binocular vision in the brain.

    Thank you for replies. Frankly speaking I've never fully understand
    this subjective and objective angle thing.
    I've done some searching for the ARC topic and if I understand
    correctly, non-zero subjective angle with zero
    objective angle means that altrought my eyeballs appear to be
    straight, my "subjective visual perception" is
    like they werent, because brain is used to use non corresponding
    retina areas. Is this correct ?
    Recently Ive noticed that I have diplopia when i look at an small
    lighting object in a dark room. Is this is
    normal in this circumstances ? (lack of fusion and subjective
    strabismus angle) Im not sure if I have it
    before or my condition has become worse lately. And my last question
    is: is there any pending research
    to restore (reconstruct) fusion and stereopsis in adults ? or is this
    still far beyond of reach of current medicine...
