You know how your phone screen feels like staring into a tiny, angry sun at 2 AM? That’s because it is. Your Kindle is different. It uses something called front light, not backlight.
Think of it like this: a phone screen shines light at your eyes, like a flashlight pointed at your face. A Kindle shines light down onto the e-ink display, like a tiny reading lamp sitting on top of the page. That’s why it doesn’t hurt your eyes. Pretty neat, right?
