Screen Time & Your Brain
It's not the blue light, it's the attention training
The problem with screens isn't really the blue light. It's what screens do to your attention. Constant notifications, endless scrolling, and rapid content switching train your brain to expect novelty every few seconds, and that training carries over into the rest of your life. Tasks that demand sustained focus start to feel uncomfortable in ways they didn't before.
What looks like a willpower problem ("I can't focus on this book anymore") is often a habit problem: your attention has been shaped by years of high-frequency stimulation, and slow content now feels under-stimulating. The fix isn't a digital detox or specialized glasses. It's friction: keeping the phone in another room when you need to focus, turning off most notifications, and deliberately practicing sustained attention on long-form content. The attention system, like any other, responds to what you train it on.
