    i usually use my laptop at night in bed with all light switched off. my mom has been complaining that this is very bad to my eyes. Is this true?? I know that the CRT screens are bad to eyes esp. if u use it in darkness. i thought that this doesnt apply to the LCD screen. am i mistaken ??

    hmm great...... however i think this damage is quite smaller than that caused due to a CRT screen... also will setting the screen to low briteness have any effect on this ??

    No it's not about CRTs, it's about the contrasting very bright and very dark.

    Lowering the brightness settings helps a bit, but it's really still bright vs dark.

    The thing is though with a laptop depends on how close you are, if it fills your view and you don't look away much it's fine, but if you're alternating back and forth between bright/dark, that's when you have the issues. And it's not really a permanent issue so much as fatigue/eyestrain.

    This is more about what your mom's talking about;

    And if you sit far enough away from your monitor it will still be an issue, LCD, CRT, OLED or otherwise.

    Just keep the light on... When you feel sleepy, turn off the light and sleep.

    Did you read that article? Not according to the article.. they say

    It's not about the contrast it's about the light/uv rays emitted from the LCD.. changing the contrast isn't going to make a darn bit of difference in that :p

    If the contrast is the issue, why not buy a portable USB light for the laptop?

    Yeah, I read it, and discounted it as irrelevant to what he was writing about.
    Did YOU bother to read what he was writing?

    Your issue is still minor and as your own article mentions, primarily for older people and infants, neither of which fits the category of the OP, so perhaps you should read them more closely, huh?

    And it won't matter to him either since the UV level is minute, and also he's not an infant or elderly chap. How do you even know it uses a CCFL backlit, for all he wrote it could be LEDlit, or it's a Glossy Screen with the standard GLASS screen with coating, then what do you have? :p
