Headaches



  • I started using f.lux for Windows, mainly because I have trouble sleeping, and if I do sleep it is not of good quality. I also installed Twilight on my mobile phone, as I tend to use my devices late in the evening.

    I am very interested by the concept of filtering out the blue light, but I am noticing that since using these blue light filters on my PC and phone, I have a banging headache. I actually feel strained looking at the screen with the filter on (when I turn it off temporarily, admittedly it's even worse, it feels like I am being blinded!)

    Has anyone experienced similar issues such as eye strain and headaches when using the filter? Also, has anyone noticed that they feel they sleep better and feel refreshed etc since using f.lux?

    Would love people's opinions :)

    Thanks



  • F.lux by itself can't do anything special. If you're still exposed to stimulating or "alerting" light after using a computer that has f.lux installed and set to some super-warm color temperature, then you're basically not benefiting from f.lux. So, it's not going to "work miracles" as they say.

    Imaging someone using their computer right before bed (with f.lux on and VERY warm), turning it off, getting up, turning on some bright lights, going into the bathroom, turning on the bright lights and then brushing their teeth or whatever. I mean, really, that's just not good. It's best to try to simulate the effect of a sunset and then finally turn off all the lights and go to sleep.

    As for getting headaches, wow, I don't have a clue. Maybe f.lux is somehow causing the display to flicker.

    The eye strain and headaches you are experiencing may be caused by setting the screen brightness too low for your eyes to focus comfortably since warmer colors have lower intensity. Try adjusting the brightness a little higher than the current setting that is causing the strain. You can also adjust the lighting in the room that you are using the device in to a brightness that is relatively lower than your screen. Also avoid having just certain areas lighted in your room, like a lamp that only lights up a small area. Non uniform lighting around you can also affect the eyes.

    Hope these helps rid you of your ailments. Cheers.
