Double vision eye strain

    I have had a chronic problems with double vision for about 5 years.
    The problem seems to be getting progressively worse. It all started a
    few years after working in computers. Back around 1998 I started
    working as a computer support technician. I was on the computer all
    day and then would come home and work on the computer.

    Around 1999 I began noticing some focusing and slight double vision
    problems while driving. The problem would go away for a year only to
    resurface. Now the problem seems to occur more frequently. For
    example, I go to a hockey game and it's hard to focus while watching
    the game.

    I went to an optomitrist and they did all the tests. They were all
    normal. But she didn't seem to care to much about my focusing and
    double vision problems. I do have a pair of glasses that are only a
    very slight correction. I only have to wear them at movies or looking
    long distance. The eye doctor told me to wear them all the time. I
    have been for a couple of weeks. At first my eyes got better for a
    couple of days but then they went back to the problems. I've talked
    to other people who are on the computer all day and they have
    different problems but don't mention the double vision and focusing
    problems. What the heck is wrong with me?

    By the way my problem is not "blurred vision". When I explained this
    to the eye doctor she kept thinking I had blurred vision.

    I worry that this problem will keep getting worse and I'll get to the
    point where I won't be able to focus at all. Ok i tend to
    catatrophize but hey why doesn't this get any better?

    Anybody have any solutions for me? Is there something I can do about
    this problem? Please point me in right directions to start helping my
    problem. Thanks.

    I would advise you to see another doctor. You might want to choose an
    ophthalmologist, especially one that specializes in eye muscles
    disorders. I work for an ophthalmologist and your complaint is a
    relatively common one.

    First off, I would like to say that using computers (albeit rather
    intensively) did not create your problems, it simply made you more
    aware of it. Many people have trouble with either over- or
    under-focusing when doing near tasks. On exam, the first thing to
    look for is some sort of glasses prescription. You must be sure to
    eliminate any blur before you can address the issue of double images.

    Here's what I mean by over- or under-focusing: When we look at things
    close up, our eyes are supposed to cross a little. The closer you
    get, the more crossing. Over-focusing means that so much crossing is
    going on that one eye (or the other; they may alternate) turns
    completely toward the nose, but the other doesn't. Under-focusing
    means that the eyes aren't crossing enough. Hence, two separate
    images (one from each eye) = double vision.

    Keep in mind that each eye is controlled by six muscles and they
    *must* work together in order to keep a clear, single image. If
    anything goes even slightly wrong with even just one muscle, you have
    trouble. One way of checking to see if it truly is an eye muscle
    problem is to cover one eye (doesn't matter which one). If things
    clear up, that's the ticket! Now, don't be disheartened if it
    *doesn't* clear up. It means that either the deviation is a very
    small one or you've been struggling with the problem so long you can't
    stop over-compensating.

    If a muscle imbalance is your trouble, then there are things that can
    be done that are benign. By that, I mean that surgery isn't
    necessarily in your future, so don't catastrophize! There is a
    special prescription that can be ground into the lens. And, believe
    it or not, there is an eye exercise you can do to help but it only
    works if you are under-focusing. This is the *only* time eye
    exercises can actually improve vision.

    The other thing I would like to mention is that painkillers and muscle
    relaxants (of prescription strength) taken on a regular basis can also
    produce the symptoms you describe. Again, it is a common complaint
    among our patients. I recently experienced this myself when I was
    given OxyContin and muscle relaxants after a severe car accident. My
    vision drove me nuts for a while. I even have a pair of reading
    glasses I needed to be able to continue to read and use my computer.

    I hope this gives a direction to look for some answers! Don't
    hesitate to ask any questions:
