I notice when using an iPhone it makes my pupils dilate - even when keeping the brightness at a sensible level. It's weird, but there may be more blue light on a mobile device than a PC monitor, perhaps I am sensitive to it.
Also I suspect that temporal dithering is the new normal in most devices. We know people with true binocular vision can see the shimmer effect too but it obviously isn't too much of a distraction. Maybe research on the effects of rendering/dithering was only carried out on test subjects with binocular vision (assuming any R&D happened in the first place). 🙂
It's just so strange how I can use this device I'm typing from fine, yet connect a new device to the same monitor and I get symptoms within minutes. It's not psychosomatic or hyperbole, and I've been through so many devices over the years for it all to be placebo. Thankfully it's not all in my head, otherwise this forum wouldn't be here.
I have had a MRI of brain/globes in the last 5 years and that was normal. So my brain is OK, I do have a high glasses prescription and strabismus, but I have always had this, my prescription has been stable for at least 15 years, and I did not have any of these symptoms 15 years ago, and was using computers just as much as I do now.
It's on the shoulders of the tech companies to address solutions for people with accessibility issues. Libretro have recently released a Retroarch (multi-system emulator) update to allow blind users to play video games. It's really innovative stuff. We now have dark mode on many apps. Windows has had DPI scaling and high contrast forever. Such settings are intended for users with partial sight/blind. I am sure a proportion of this demographic do not have binocular vision, and it shouldn't be the gateway to use tech anyway.
