    Re: Are pervasive low blue light display features a waste of time?

    I've always thought the body clock bit was rubbish, but a warm k setting is nicer to look at when it gets dark so I'll use it at night anyway. Cold/normal settings do feel more aggressive on the eyes at night, but I'll leave them on if I'm doing something colour-critical (photo edits or graphics work).

    I just make the monitor go to sRGB mode and use F.lux so that's as good as it gets.

    Username not helping affirm that assertion... I've not heard of anything else that might be Friesian. Can you get French Friesians... are they good with ketchup?

    I already have my monitor turned down to 5% brightness as standard, because gaming monitors seem made to blind you. The LBL mode does help further, if ever I find my eyeballs feeling clawed at by the screen, but I don't believe it has any particular effect on me otherwise.

    Every bulb in my house is now a daylight bulb, bathroom looks white both day and night.

    Not effected the sleep of anybody in the house.

    As a photographer my monitors are calibrated so to adjust them out of spec depending on time of day would be silly, past that other screens are calibrated so its not jarring going form one to another. On that front most TVs are very cool out of the box I have found.

I think it must have some affect as I have found it easier to fall asleep in some circumstances (but that could just be exhaustion from children waking me at night).
    It could also be a placebo effect - it works for you because you expect it to. But if it works, it works.
    Or just the general reduction in brightness. I've never seen any measurements but as these software modes don't generally have control of the backlight I'd expect the total light output to be reduced rather than kept the same and shifted to a different part of the spectrum.

    The blue light stuff was always dubious and seemed to be a case of the marketing rushing ahead of the science. I think the only research when they started being introduced was that there was a third type of photoreceptor in the eye that was sensitive to blue light and looked like it might have something to do with the day/night cycle. It's not at all a surprise that further science has shown it not to work as speculated.

    Never used the low blue light feature myself, as I just go to sleep if I'm tired, no blue light has ever kept me awake.
