If I’m in a hotel or somewhere where I can’t change the brightness&amp;#x2F;colours then I get more headaches again.&lt;p&gt;It absolutely hasn’t cured me, and I still have both issues, but there has been a noticeable increase in quality of life and ability to use screens at night.&lt;p&gt;Our screens are way too bright because it looks good for marketing purposes. You get used to very low screen brightnesses very quickly, even on your TV, and whether it’s blue light or just brightness in general, I definitely think all these bright lights shined into our eyeballs at close range are doing damage.</text><parent_chain><item><author>mgraczyk</author><text>Anecdotally, I can pretty reliably trigger a migraine by staying up 2-3 hours later than normal staring at a normal LCD screen.&lt;p&gt;With flux&amp;#x2F;redshift on, that doesn&amp;#x27;t happen.

Anything related to sleep or headaches there could be a psychological factor ie because you “know” blue light is bad it becomes a self fulfilling prophecy.</text><parent_chain><item><author>mgraczyk</author><text>Anecdotally, I can pretty reliably trigger a migraine by staying up 2-3 hours later than normal staring at a normal LCD screen.&lt;p&gt;With flux&amp;#x2F;redshift on, that doesn&amp;#x27;t happen.
