    I've been staring at computer screens for 12 years just fine, often
    many hours a day, until about a year ago. Since then, after about 4
    minutes of looking at the screen, my eyes feel like...well, they feel
    like when you look out from the extreme corners of your eyes for a
    long period of time, only this happens when I'm looking straight at
    the screen. My veins in my eyes become quite red and noticeable. My
    eyes will remain like this (both hurting and red) for many hours after
    I'm done with the computer.

    I've tried using different monitors: a CRT and an LCD (both are
    adjusted properly regarding contrast and brightness) and adjusted the
    height of the screens. I have taken breaks for many days at a time
    where I wouldn't look at a computer screen, only to find that when I
    came back my eyes would still hurt after a few minutes. I've even worn
    sunglasses while using the computer to make sure it wasn't the
    brightness. I saw my optometrist a week ago for an eye exam, and he
    said everything looked normal. Quite frankly, I don't know what to do.
    If I don't get this fixed I will definitely have to change my career,
    as I simply can't bare looking at a computer screen anymore. :(

    Though I'm not an eye doctor, I have a couple of ideas that you may
    consider:

    1) you could have mild dry eyes. "Staring" at computer screens
    involves reduced blinking. That leads to dryness. Find an
    over-the-counter, PRESERVATIVE-FREE lubricant drop (pick one) and try
    it for two weeks. At the same time, TRY to increase the frequency of
    your blink rate;

    2) When you say that the optometrist said "everything looked normal,"
    did he say that you do not need reading glasses? How old are you? Do
    you wear any kind of corrective lenses already? If so, what is the
    prescription? Did he "dilate" your eyes to measure your eyesight?

    What I'm getting at here is that your eyes may simply be getting
    older, and your "accommodative amplitudes" (ability to shift focus
    from far to near) may be diminishing ... as they do, normally. If
    this is the case, you might simply need reading glasses for computer
    work.

    3) Did they evaluate the alignment of your eyes (follow the light ...
    up ... down ... left ... right, and a "cover test" where they cover
    one eye, then pull the cover away, then cover the other eye, then pull
    the cover away)?

    4) is your work space well set up for ergonomics and visual hygiene?
    (easily googled)?

    Please provide some more detail about #'s 2 and 3 above. I'm sure the
    friendly, neighborhood eye docs will give their input ;-)

    Forgot to mention that this doesn't happen while I'm watching TV on
    any of my TV's, but it does still occur If I'm watching a video on my
    computer.

    I'm 21 years old and myopic. I do wear glasses for it. I can't find my
    prescription at the moment, I'll post it when I find it. He tested for
    everything you mentioned and my prescription remains unchanged.

    Hi,
    Read and refresh.Need not change your career for this.

    Many of you have jobs that require you to work on the computer. These
    strenuous computer-intensive work conditions have given rise to what
    is known as Computer Vision Syndrome.

    DON'T MISS: Eye care tips for computer users
    Dr Amar Agarwal, a practising ophthalmologist (eye specialist) based
    inChennai, says that this occurs "when there is a shortening of tear
    break up time. In other words, tears that form a defensive film over
    the eyes start drying up. This occurs when the eyes are open and
    looking into the monitor for too long. The tears evaporate from the
    eyes faster, causing the eyes to dry up."

    CVS could lead to various eye problems.

    A good workout? Only 20 minutes
    i. Eyestrain

    Eyestrain, which is a common problem, mostly occurs when we are
    working on something for a long time without taking adequate breaks.
    It can be caused by activities such as watching television, working on
    the computer, reading a book or studying for long hours. In such
    cases, your eye muscles are working hard to help you focus.

    During these times, your inner eye muscles tighten up, causing your
    eyes to get irritated, dry up and feel uncomfortable. In addition,
    lack of sleep, fatigue, poor lighting and an incorrect posture (such
    as slouching on your chair), can aggravate eyestrain.

    Symptoms include a mild headache, coupled with irritated/ smarting
    eyes. You might also find it difficult to focus after a prolonged
    session of reading or looking at your computer screen.

    Prevention: Apart from placing your monitor 25 inches away from where
    you sit, tilt it a little below eye level. How does this help? Dr
    Belvi says, "When your eyes are looking down at a lower level, they
    are opened less as compared to when you look directly into a monitor
    tilted at a higher level. Thus, keeping the monitor at a lower level
    helps minimise evaporation of moisture from your eyes."

    Opt for LCD/ plasma monitors as they are more soothing, compared to
    cathode ray tube monitors. "LCD or plasma monitors are technologically
    more advanced. As a result, the pixilated picture quality and colour
    contrast are soothing to the eyes. Compared to that, cathode ray tube
    monitors are harsh on the eyes as they display focused light on the
    eyes," he adds.

    You can also set the lighting and brightness of your monitor to a
    lower glare, as per your comfort level.

    Do or diet? Tips that can't go wrong!
    ii. Dry Eyes

    This problem can be worse for those who wear contact lenses to work on
    a daily basis. Dry eyes occur when our blink rate declines
    considerably while working on a computer. More so since we are looking
    straight ahead into the monitor, as compared to desk work where we
    look down at our books/ files.

    The very act of looking into a monitor without blinking results in
    tear evaporation. An air-conditioned office environment also
    contributes to this problem, dehydrating our eyes and causing them to
    itch.

    Some of the basic symptoms of dry eyes are a feeling of dryness and
    irritation, a gritty/ grainy feeling in the eyes, a blurring of
    vision, redness, feeling a strain on the eyes, general stress, an
    intolerance to light, and headaches.

    Prevention: Follow certain precautions like keeping a minimum distance
    of 25 inches from the screen.

    Fix an antiglare screen on your monitor.Anti Reflection Coating on the
    Lens.

    Take regular visual breaks lasting few minutes, at intervals of 20
    minutes -- such as looking away from the screen for about a minute and
    then getting back to work. This will help your eyes focus better.

    Blink your eyes several times so they are nourished with tears.

    Use preservative-free re-wetting eye drops; these can be safely used
    even by those of you who wear contact lenses.

    iii. Vision related headaches

    Most of us have suffered from vision related headaches. These signal
    eyestrain and are usually caused by improper workplace conditions.
    Glare from the computer screen and poor lighting are some of the main
    culprits. Some of the main symptoms include headaches that occur
    mostly toward the front part of your head or forehead, and you finding
    yourself pressing the point between your eyes and upper part of your
    nose.

    Prevention: If at home, have lemon tea. If at work, try a hot cup of
    tea, as it helps soothe headaches.

    "The best thing is to get some rest for yourself and for your eyes,"
    suggests Dr Amar,

    Hi
    One more for you.
    Computer vision syndrome is a common complaint of office workers more
    prevalent in the last years due to the widespread use of computers and
    video display terminals (VDT?s). Common symptoms include sore and
    irritated eyes, dry eyes, headaches and blurry vision. But
    fortunately, there are many ways to enhance your work environment to
    help prevent computer vision syndrome.

    Computer images are made up of tiny dots that do not give a clear
    image so your eyes are forced to focus and re-focus continually. This
    is one of the main reasons that computer work is so straining on the
    eyes.

    Ensure that you are working with a good quality computer screen and
    make sure the resolution is set high as high as possible for your
    work.

    Force yourself to blink more often than usual and use mild lubricating
    drops if you experience dry eyes. Take ?eye breaks ? at least every 20
    minutes by looking away from the screen and focusing on something in
    the distance for at least 20 seconds.

    Ensure that the lighting at your workstation is appropriate for
    working at the computer. Make sure there are no bright lights shining
    into your eyes or your computer screen. Don?t make the mistake of
    having too much light. Too many light sources within one space will
    distract your eyes from the screen and cause glare on your screen.

    Make sure that neither you nor your screen are facing a window.

    If glare is a problem try changing the position of your desk. Hang
    pictures or temporary walls to eliminate other sources of light.

    Reflections can be very straining for the eyes. Two types of
    reflections exist, diffuse and blocking. Diffuse reflections are those
    reflections caused by a reduction in the contrast of text presented on
    the screen. Low contrast makes it difficult for the eyes to focus.
    Blocking reflections block out parts of the screen, which forces you
    to move in order to see the object.

    Reflections can be prevented by either using anti-reflection filters
    on the screen or by eliminating the reflection source. If too much
    light is coming in through the window, used blinds or curtains. Always
    try out different positions. It is often the case that computer users
    are not even aware of the discomfort they are experiencing because
    they have become so ?used to it?.

    The positioning of the monitor in respect to your posture can make all
    the difference in the world. The computer screen should be at an angle
    of 0 to 20 degrees from a straight visual line looking down slightly.
    And keep your screen 50-60 cm away from your face.

    Computer glasses

    If you are over 40 chances are that you already use glasses. And if
    you already wear glasses or contact lenses it is not guaranteed that
    you might not need separate glasses for working at the computer
    screen. Those who wear bifocals or trifocals are often forced to move
    their heads so that they can see the screen through the right section
    of the glasses. Glasses and contacts usually correct near and far
    vision and sometimes both but rarely do they correct the mid-range
    needed for a computer screen. Even if you wear contact lenses you may
    still benefit from computer glasses.

    Computer glasses provide a wide field of view so that users can
    clearly read their screen and printed material that are at different
    distances and correct the distance held looking at a computer screen.

    Tinted glasses are also available to help prevent glare from computer
    screens and surplus lighting (not needed but cannot be switched off).

    If you are experiencing eye problems while working at a computer
    screen it is a good idea to see your eyecare specialist for a thorough
    eye exam and ask him/her for their recommendations.

    Summary of Steps for Preventing CVS



    Use good quality monitor

    Set resolution high

    Make an effort to blink your eyes more often

    Ensure proper lighting at your workstation

    Don?t have you or screen facing a window

    Eliminate any sources of glare in the office

    Angle your computer slightly below eye level

    Position your monitor 50 to 60 cm away from your eyes

    See your eyecare specialist for an eye checkup to determine if you
    need computer glasses.

    As a myope, you can eliminate many "CVS" problems by taking off your glasses
    It happens with and without my glasses.
    Nothing, as much as I can remember.

    I bought lubricating eye drops yesterday and tried them out. The only
    preservative free eye drops I found out were Genteal Mild, so I got
    those. They seemed to help for a few hours yesterday when I put them
    in before using the computer. Today, I was on my pc for a bit prior to
    the drops, thus my eyes hurt right now and I can't really tell if it's
    a case of dry eyes. I'll continue with the drops for a while and see
    if thats the problem.

    Does it change if you try another monitor in the same place?
    Woops, I meant to say no there. Tried 2 monitors and a laptop in the
    same spot and all with the same effect.
