Toric contacts and using computer at work

    I just got my first pair of contacts last year which are torics
    because of my astigmatism. Problem is that when I use my computer my
    vision is blured and no where near as clear as when I'm wearing my
    glasses. As a result I have to wear my glasses which defeats the
    purpose of why I wanted contacts. Is this normal with toric contacts
    or are they not fitted appropriately?

    You didn't mention your age or whether the blur is ony noticed
    on the computer (ie. is your distance vision fine with the cl's ?).
    In general, you shouldn't have problems with the cl's while on the
    computer unless they're drying out or you're over 40. Sometimes
    oan individual will stare at the monitor that can cause drying of the
    lens. You might want to try a rewetting agent to see if this helps the
    blur at all.

    Other docs may have different experiences, but I've found correction
    of low astigmats with no significant myopic/hyperopic refractive
    errors with soft torics to be a more difficult population for success
    than in other groups.

    Obviously, you should discuss this problem with your cl provider to
    see if there are any problems. Good luck.

    My distance vision with the contacts seems to fine. I'm 29 years old
    so below the 40 threshold you mentioned above. What type of contacts
    would you recommend? I'm just trying to get as much data as possible
    so I can hold an informed conversation with my optomotrist. Thanks.

    I've always had an issue with contacts that I tend to only notice when
    looking at a computer screen (which I do 10+ hours a day), so I'll
    share my experience and you can see if you're having the same issue.

    Basically, when I wear contacts I get somewhat of a ghosting effect
    where I'll see a ghost image of an object 50-75% above the "real"
    copy. I usually only notice it when I'm looking at something light on
    a dark background, e.g. light computer text on a dark background
    color. At first I thought it was just normal blurriness, but when I
    looked closely I saw that the test was ghosting, and the ghost copy
    blends in with both the original copy as well as adjacent lines of
    text, etc. So the end result is basically the same as normal

    The most common cause for this type of ghosting seems to be
    astigmatism. The doctors that I've seen however say that I have only
    a very slight astigmatism that normally they wouldn't even bother with
    trying to correct via toric lenses. And when I've tried toric lenses
    they haven't made things any better. So I don't know what the deal
    is. I get the effect without contacts as well but since things are
    blurry anyway I don't notice. I don't get the effect with glasses.

    The easiest test for this is to look at a digital clock (with red
    digits) in a dark room. I can very clearly see the "ghost digits" in
    this case.

    So, I haven't found a solution to this (maybe I just haven't seen a
    good enough doctor) and am just "dealing with it". It's not so bad
    that I *have* to wear glasses when I'm looking at a monitor - now I
    just wear the contacts at work (where there is more lighting, hence I
    don't notice the ghosting as much) and wear glasses at home where I
    tend to keep the lights lower. It sucks but the 3 doctors I've seen
    were dumbfounded and I don't have the time or money to see doctor
    after doctor after doctor looking for a solution. If this is your
    issue and you find a good solution let me know!

    I am in a similar situation as you only a -4.5 and a computer user 10hrs
    a day. And my eyes do get drier now with Torics than before and hence
    blur my vision. The doc said that wihle working on the computer, our
    blinking rate (what lubricates the eyes) goes down by two-thirds.

    The other problem I've encourtered is that they turn on me - not
    necessarily upside down, but perhaps 90 degrees, which is enough to
    through them off. Your contacts might be a different design and not be
    subject to that problem.

    BTW - I've lived with .75 of astigmatism a long time without correction
    and never complained about computer work because of it - only distance.

    I just wonder if it's indeed a problem with your cl's drying out(your blink rate
    is less while on the computer versus looking out at the distance); at your
    age you should have ample accommodative (ie focusing) amplitude to handle
    the duties at near. I would really be liberal with the rewetting agents to see
    if that's the problem. Without knowing the material or brand of the toric lens
    you're wearing, I'd suggest asking your doc to try another material - one that
    wont dehydrate as much (ie. lose water content). Personally, I like the proclear
    torics myself. Sometimes using punctal plugs (for dry eye patients ) does the trick
    as well.

    Thanks Frank. FYI: I'm currently wearing Acuvue Torics.

    My experience with computers and contacts is mainly with gaming, which
    requires extremely rapid eye movement, this causes toric lenses that I
    have used to constantly misalign and lose focus. I have taken drying
    into account, and used endless amounts of rewetting drops to no
    effect, I'm fairly sure it is the 'unnatural' speed of eye movement
    involved in high intensity online gaming.

    I would imagine that athletes deal with this also, and I'd be
    interested in finding a contact lense that performed better than the
    Acuvue2 Toric I'm using.

    Anyway, from my experience, contacts not compatible with computer
    gaming, at least not torics. Perhaps the orginal poster has an
    application that causes similar rapid eye movements (porn? sorry,
    couldn't help that one...) j/k! :)

    My toric experience is exactly opposite. When I do things that involve
    eye movement (computer, TV, reading) the focus stays OK. Freeway
    driving, however, causes one lens to eventually go blurry and it takes a
    while (and sometimes some eyedrops) to come back.
