hpst I too think blue light is not the worst guy out there. It is probably producing some long term effect, besides disturbing sleep, but it is not responsible for the immediate eyestrain that many of us feel in front of "bad" devices. However, I am bothered by some type of lightning as well, and that cannot be dithering. I suspect flickering rather than blue light.
Are you struggling only with displays?
On a different note, I withdraw my desperate speculation that acupuncture could have worsen my situation. I went in yesterday and I showed the osteopath the twitching of my eyes' muscles. Post-treatment I had relaxed and only around the left eye I could feel some tension. I stayed 16 hours without electronics and felt almost healed. Then I messed around for a couple of hours with a DELL Latitude E5570 mounting an Intel (R) HD Graphics 530 and on Windows 7, and to my surprise I survived very well without even adjusting the brightness and reducing the display resolution. Finally I turned my MacBook Air on, and muscle twitching / neck tension began within minutes :-(
I read some of you felt eyestrain after updating their browser. Question: could you ascertain the strain came only from the app which you updated? I am considering uninstalling and reinstalling Office, which has been my only (undesired) recent update. I am also worried it could be the screen, as it went black a couple of times within seconds. How long are LED displays supposed to live for and what do they typically die of? Thanks.
