Are f-lux and blue light blocking glasses the same?

  • I'm wondering what's the difference between f-lux and glasses that filter blue light. I read that softwares like f-lux don't act on the blue light emitted by the backlight of LED monitors, is that true?

  • Well the main difference is in how much room lighting is filtered. So if you have bright room lighting and can't adjust it (like at the office) you might wear glasses for that.

    If you're worried about backlight leakage through "black" pixels, well, I wouldn't worry at all - the amounts of light are so small that they don't have an effect, when compared to anything that's not black.
