Books with white pages don't emit light, a screen with white backgrounds does

    It's like staring into a lamp.

    I like to think of it as staring into a fire

    The sun at dusk will still burn your eyes.

    I've been reading a dark mode book on an OLED screen and it's such a treat. The background is pitch black but I crank the brightness up so there is a high contrast and the white letters look really sharp. It actually makes it easier to read

    Unless it's an e-ink screen... then, it doesn't emit light

    And these also don't need a dark mode.

    They don't... But the option is still there if you want an emo-ink display

    I use my e-reader’s dark mode when I am reading in the dark and the backlight is on. So, in the one instance where it is actually emitting light.

    Even with the "backlight" it's far less harsh than an LCD or OLED panel because it's not actually a back light, e-ink display have a "frontlight" that actually directs the light back at the display instead of from behind it facing outward towards the user

    FYI ereaders don't emit light even with the light on. They use lights hidden on the sides under the bezels, and that light gets distributed above the screen using a kind of gel layer. The screen then reflects that light back.

    Isn’t the device emitting light though, if not the screen itself? I don’t know if there is a technical definition of “emit” that is narrower, but I just meant that there is one time where the device itself is the brightest thing in the room and dark mode reduces that.

    Yeah I guess that's fair, but I think that the fact that the light isn't directly shining in your eyes but is reflected, makes quite a difference. Still, use whatever mode feels most comfortable to you! Just sharing knowledge.

    They do reflect it, though...

    As someone with sensory issues, absolutely they do. I used to struggle so hard in school when I was supposed to stare at white paper in a well-lit room. I'm not sure if most people notice just how fucking bright paper can be xD

    Yeah for whatever reason, textbook paper always has a glossy finish to it. Combine that with bright overhead fluorescent lights in a school and I could see how that could be irritating as fuck.

    Other types of written material don't seem to have a glossy sheen like works of fiction and dictionaries. Do you still have issues with those or no?

    Because we know. That's how vision works. But it's missing the whole point. Would you rather get shot directly from a gun or from a ricochet?

    Everything refects lights, that's how our eyes see!
