Not just screens. Books are just as bad. Human eyes aren't really optimized for staring at a single fixed distance for hours at a time, every single day.

You're right on most points, but in the south it's definitely more than 15 minutes a year. Those fuckers are even blinding in the daytime.

I might have missed something, but who's anti car? You're ABSOLUTELY correct about screen time; but it is worth noting that the amount of prescriptions for night driving glasses are higher than they've been in history. I travel often and, even in my SUV, I can't stand that large/superduty truck lights don't point downward enough... It's downright blinding at times. I can't imagine what someone in a sedan is seeing. It's not just passing them at night, you get hit through rear view mirrors if they're behind you and at red lights, too, which can add up to multiple hours a week depending on your commute/schedule. The laws in the 90s were based on fluorescent brightness, and should probably be updated, that's all. It's not truck owners fault that the lights are designed like that.
