Eye strain from PC

Discussion in 'Eye-Care' started by Terry Pinnell, Oct 12, 2008.

  1. Over the last 4-6 months I've been getting a lot of headaches which
    are getting steadily worse. I'm now pretty sure they are due to
    eyestrain caused by my excessive PC usage. I'm my own worst enemy in
    this regard, spending 10-12 hours per day at my PC, 5-6 days per week,
    but I'm addicted!

    I had an eye examination (all OK) and eyesight test leading to a small
    change in the prescription of the glasses I use specifically for the

    Short of the breaking out of this regime is there anything I can do by
    way of screen height, distance, posture, etc, to reduce the problem?
    And are there any exercises I can do to help my eyes recover from long
    periods staring at a 24" widescreen LCD monitor from about 65 cm?

    In case it's relevant, these headaches are almost always on one side
    (my left), and I'm wondering if I'm using the left eye significantly
    more than the right? For instance, as I type this in my newsreader
    program, Agent, the text occupies less than a third of the screen, so
    I'm obviously looking leftwards.

    Is there any reason why an LCD screen should cause eyestrain more than
    a CRT? My previous 19" CRT monitor, used just as much, didn't cause
    such serious headaches. I'd have expected the opposite, given the
    inherent flicker. Regarding that, there seems no way to change the
    refresh rate (60 Hz) of this Iiyama monitor. But what does 'refresh
    rate' mean for an LCD/TFT screen anyway?

    Any advice would be much appreciated please.

    You can't change the refresh rate of most LCD's. It needs to be at 60 Hz.
    Some of the higher-end LCD TV's are now offering 120 Hz refresh rates, but I
    have not seen this in a computer monitor yet.
