one of the most essential pieces of software in my opinion: flux: https://justgetflux.com/ and now that I've been running linux, redshift: http://jonls.dk/redshift/ I find it hard to use a computer without these now

Flux has been awesome for me, I've been using it for a long time. Redshift more recently, but does a good job too. Twilight for Android is a very nice counterpart for my phone.

Earlier quoted context omitted.

Well no cure aside maybe not looking at a backlight. I really wish there were marketed displays without a backlight. There's got to be a way.

I've been wanting this for ages. And more simply, I want brightness controls that go all the way down to zero.

Seems like there could be a Kickstarter. I'd want a high resolution external eink display as a secondary monitor. The refresh rate would be hell, but it'd be okay for text work.

flux&al adjust colour temp, but be very kind on the backlight any time of the day. Some screens are so stupidly bright it's like staring at a bright bulb all day long. If at all possible use a screen that adjusts backlight automatically according to ambient light. And no, you really don't need that much brightness, just don't turn it all the way down either!

Do you know any good automatic-adjustment add-ons? I'd like to use the OS X option, but it seems to automatically adjust to ~2 notches above what I want. So something to use the same relative changes, but a lower absolute brightness, would be perfect. Right now I just do it by hand.

Flux is awesome, I even use it on my led tv

My retired optometrist friend recommended that I wear reading glasses with a very low power at all times while using the computer, and I do that now. They're .75x or 1x, I can't remember. I don't need them--nothing is blurry without them--but they help your lenses to relax by doing some of their work at close distances. The condition he wants me to avoid is called nearpoint stress, but sounds very similar to me (a la…

You have to be careful with OTC reading glasses. If your reading PD is much more narrow or wider than about 57mm, then you're introducing prism. At the powers you've mentioned, it _shouldn't_ be a problem, but higher powers can cause headaches and eye strain.

I use to get headaches every day (the kind that seem to originate behind the bridge of the nose). One day in effort to reduce the ache (a desperation move I didn't know would work out not) I reduced the brightness level in my monitor to the lowest possible setting. It slightly helped me cope with the rest of the day at work, but I forgot to reset the monitor. The next day I didn't get a headache. Turning down the bri…

The human body has a tendency to attempt to attenuate sensory input. The process you describe is similar to a practice in audio engineering where by an audio engineer will start with the lowest volume and gradually turn the volume up. If you start the volume high to begin with, your ear (and in your case your eyes) will attenuate the sensory input down which causes unnecessary strain.

Agreed. It's been 20 years that I use low brightness (and not too high contrast), plus I code on dark background.

Another thing I noticed helps is some other light source in the room, possibly a desktop lamp to light the wall behind the screen. It bothers me if the screen is the only light source in the room.

Yep I used to get them too, sore eyes also and weird squinting. I run my screen at about 2/3 or 3/4 brightness, I use a dark theme in my IDE and I also always bump up the font size. Doing all this I don't get headaches or eye squinting anymore.

Also I use flux and try not to use the computer much at weekends.
