Something to do with the blue emission from the lights.

I noticed Zenni optical is offering blue light protection in all its glasses. My eyes are sensitive to light, and I wonder if I should get some.

I hate LED lights. Not sure I have a choice with my light fixtures, but I can never get the right amount to where I am not shading my face with my hand. Right now with natural light is the best time of the day for computer work and play.

What I dont like are those super bright headlights on new cars. They are so blue/white and look like high beams are on but they arent. Its really distracting on a two lane road in the dark. Takes my eyes a bit to re-accustom to the darkness.

I agree. Many of these new headlights are safety hazards.

OK so the screen on my phone goes dark when not in use. How is that bad to leave in/next to the bed?

Those are horrible and a hazard to other drivers.

That's part of the reason I don't drive at night.

Computer and smart phones will display a bluish light, even when viewing a white page, by default. You can adjust the blue out of your computer screens, but not sure about smart phones. Go to PH (white #FFFFFF background) on your computer in a dark room and the light will be bluish.

Samsung phones to me are the worst:

1. they have heavy blue in their screens
2. they use a blue indicator light (that lights up the whole room) if someone calls, leaves a message, etc.

If it buzzed, rang or otherwise made a noise, would you look at it? To me, that's enough to remove it, its a distraction.

I had a lot of sleep trouble but my doctor suggested removing all phones, no media 30+ minutes before bed and off-the-shelf melatonin.

I sleep very well now, probably largely due to the melatonin. I take it and within 30 minutes I'm out. So I take it and go out in my backyard till it kicks in, watch the stars.
