I know when I see most people with their phones - their iPhones/iPads are at near maximum brightness. I remember a before sunrise flight where the guy next to me had his phone on MAX brightness. Was so painful.To each their own, but regarding the statement/argument that e-ink is inherently better for the eyes, I hear that from e-ink users quite a bit, but I question the science on that. I have no doubt most iPad screens are set to be much brighter and bluer and therefore harsher on our eyes than e-ink screens. But I see no reason why an iPad screen’s color and brightness can’t be programmed to match an e-ink screen’s. As far as I know, there is no other quality about photons (besides frequency and quantity) that would make a difference to our eyes. And I think with true tone and other settings on the iPad, it can be matched for all intents and purposes. It’s just that people don’t bother.
Me? I put my phones on the lowest brightness possible then use dark mode. I like using an iCarez screen protector to reduce glare (matte).
I can read for hours and hours like this on my iPads - with almost no eye strain. And DEFINITELY Night shift almost all the way over. Love that yellow.
