    I feel like I’ve seen this ad before

    Or use the awesome program ‘redshift’ which does the same thing to your computer. Noticeably helps me sleep much better when I use the computer before sleeping, it’s simple and awesome.

    available in the ubuntu repository: sudo apt-get install redshift

  4. I’m sure you know about F.lux for Macs and Linux computers; I jailbroke my iPad and iPhone recently so I could install F.lux there, and it is very, very much worthwhile.

    No suggestions for your teevee, I’m afraid.

    I have discovered that sleeping in the dark effectively blocks blue light.

    It’s AMAZING!

    I’ve been using overhead time projecting alarms for a while because I already have an anxiety related sleep disorder and being able to see the time (or just knowing I can easily see the time) helps me relax. Anyhow when my red light OHP clock died all I could find was a blue light version and I swear my sleep had been worse since.

    So, if true, this makes sense with my own experience.

  8. Been saying this forever. This blue light craze from fluorescents, and LEDS is not just silly and ugly, but dangerous. I’ve got warm tones running on all my devices (except of course when doing color accurate work), my nighttime lights are all incandescent, and I fall asleep the second my head hits the pillow. Not to mention it’s just less stressful to the eyes.

    For lights out reading on an iPad, I have a dark amber screen mode thanks to “Color Profiles”. It’s awesome!

    Are these the “As Seen on TV” repurposed “Blue Blocker” glasses? Same thing same filter as far as I can see.

    As I’ve slid into my 30s 40s I’ve found I’m sleeping less well – neatly correlated with the rise of iDevices.  It all makes sense, this blue light stuff – tons of evidence on the interwebs.  And what nailed it for me – early morning sunlight light is bluer than evening light.  Might be saying something you all already know – but clearly evolution and the early bird and the worm come into play here.

    Blue light is wakey light!  Avoid avoid avoid.

    Thanks for posting this, and the wonderful informative comments above.

    Hi Carla,
    If you’re online in Canada, or have Netflix, there was an excellent documentary about light-and-sleep interaction on a show called The Nature of Things, with David Suzuki, a longtime environmental proponent:

    The link provides an overview if you can’t watch the video, but there are glasses available and in use for shift workers that block only the bandwidths that affect alertness and sleep-cycles, providing a less-orange tinted view.  I don’t know where to get them or how much they cost, but I think the video will be of interest to you regardless.  Good Luck!
