What about good old dark editor themes or, better: Inverting of screen colours? Staring at a bright computer screen for hours is a recipe for tired, red eyes. And all operating systems offer negative screen colours. On OS X it is an accessibility option and has the standard shortcut control+option+command + 8.

Android and iOS also can do this. On iOS it's again an accessibility option, press the home button three times after it is activated and you will be able to read HN much longer (also, a black+blue HN is nice).

I am using this option so much that I finally switched from Ubuntu to OS X on the desktop after an Ubuntu upgrade at that time eliminated negative screen colours (and hibernation, but this is a different story), and it was impossible to bring it back.

I also like Flux darkroom, but after some time it gives you the feeling of being in a horror movie.

Anyone know of a break-taking app that watches your activity and can wait until you've lost focus on your work before reminding you to take a break? Something like the alarms that wake you up at the right point in your sleep cycle. It would probably need to have a cut-off eventually, but I'd hate to be interrupted in the middle of tracing some complex logic if there's a perfect stopping point 10 minutes later.

The of productivity overkill going on in this idea is painful to think about.

The world can wait. Fuck it. Just slack off and waste some time. That's what I do.

When my eyes feel bad, it's time to destroy an hour of the day, go for a walk and anyone who can't get on board with that can take a hike.

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…

Interesting, do you then prefer white-on-black or black-on-white code/text?

Against dry eyes,a micro controller and two airbrush pistols with natrium-destilled water solution. Its a shame there is no ready made solution built into or upon glasses...

PS: Huge glasses that cover the eyes also protect against moisture loss.

Turning down the brightness had the opposite effect for me. My monitor at the time "turned down the brightness" by reducing the duty cycle of the backlight. This caused flickering that was imperceptible yet caused much eyestrain. Actually turning up the brightness, moving the monitor as far back as possible, and using yellow-tinted Gunnar lenses have made a huge difference for me. Edit: This is the technique used to…

Basically every monitor with a LED backlight controls brightness by PWM. It only causes problems if the frequency is too low. (Contrast with fluorescent lights: every single fluorescent tube in existance flickers, but only some flicker slowly enough that people can notice. https://www.youtube.com/watch?v=bjyhFyUN_zQ Ditto CRT monitors, back when they were still used. Refresh rate of 60hz is flickery and annoying, ref…

There's some debate about what is flicker threshold (flicker fusion threshold ,I think).

I've seen some academic literature talking about 1000-4000hz , which is far above what most screens do.

Btw I believe BenQ has a display that doesn't use pwm at all .

I get an extreme ghosting effect after reading on an inverted color screen for even a minute or less.

I don't generally hear others complain. Maybe it's rare.

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.

I've been wanting something like this for ages. Even as a small-scale secondary monitor, it'd be great to toss static text like tickets or APIs onto an eink display.

A rule of thumb I've heard is that your monitor shouldn't be any brighter than a sheet of white paper held next to it. http://i.imgur.com/5Cwiuif.jpg Mine isn't quite that dim, but it's not nearly as bright as the view out the window behind it.

It certainly should not be the brightest thing within your sight.

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&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!

Redshift does not only set color temperature, but also screen brightness and gamma.

I feel incredibly lucky that I don't suffer from any of these symptoms, as I sit, and have sat, in front of my computer for ~14 of my available waking hours each day for the past... 10 years?

8 hours a day at work, and I then come home and game for 3 or 4 more, sometimes as much as 9 or10 additional hours, and have not yet felt anything as described here.

I may do these exercises naturally, as part of my existing habits, because I'm fairly easily distracted.
