Migraines and Eyestrain from Smartphone?

2 points by profdithering ↗ HN
Hi,

I'm looking for a new Android device (currently using an old Samsung Galaxy S5) and I've found that almost all devices (Pixel 3, Pixel 2, Samsung Galaxy S9, LG G7) cause me severe eyestrain, dizziness and migraine. I can't find a modern device that's usable for me.

I suspect that some kind of flickering, like temporal dithering, is the root cause. Does anyone know if Android phones are using temporal dithering or some other kind of flicker?

I'm aware of PWM flicker in OLED displays, but that seems to not be my problem, since Galaxy S5 is OLED, and it works great for me. I've been to several doctors (MDs), optometrists, opthamologists and neurologists -- and they've all declared me healthy. Clearly something is different about these newer devices that are causing this issue, since when I return to my Galaxy S5, my symptoms will go away. Certainly, there's something different about me, but modern medicine has no answers. So I am desperately turning to the smart folks of HN.

There's a whole community of people like me at ledstrain.org. The only "test" I've seen for temporal dithering is to connect to an e-ink display, as shown in this video's "moving dots": https://www.youtube.com/watch?v=0y-I3hqQgCQ

Does anyone have any ideas what could be causing this? I am willing to fund research into this.

Unfortunately you've provided no contact information, so hopefully you see this reply. What you've mentioned is interesting, and I may have some leads regarding this in the future.

If you see this, please get in touch, my email is in my profile. I cannot promise when I'll respond (or, admittedly, even notice your message), but I can promise definitely will eventually see it, and respond at some point.

Thanks, I just emailed you. I'd greatly appreciate any information. I fear this will affect my job and I'll have to learn some skill without computers.
