Night mode kind of differs. I think there was one piece of software that did it way before operating systems got night mode, and with the help of some measuring device they found out that most competitors turned the screen red but did not actually lower the amount of blue light much, negating the whole point (as the theory behind this stuff is that blue light messes with your sleep schedule). Your screen turning reddish yellow does very little if the effect is achieved by turning on more red and green pixels.
Sounds impossible. The way they turn the screen red is by reducing the blue light transmitted through the LCD panel. You cant turn the screen red and keep the blue light at the same time.
Unless its an oled screen. Then it is a stupid implementation. You could just reduce the blue light then.
I remember a long blog post about it on f.lux comparing it a bunch of competitors with actual measurements rather than pure RGB values.
Of course LCD doesn’t turn on any pixels, it just stops blocking the white light from behind the panel, but the result isn’t any different.
Unfortunately I can’t find the link right now, I must’ve read it a decade ago. Perhaps it’s been lost to time.
The end conclusion was that a bunch of free apps/cheap software thought they could get in on the blue light fad and turned the screen redder without significantly reducing the amount of blue light transmitted. At the time, there were one of two kits of software that actually showed a significant drop in blue light because their colour mixing algorithm/colour profile adjustments were done correctly whereas the competition just implemented it wrong.
Same. I’ve the twilight app on my phone because my phones filter is shite. Same thing with f.lux on pc and my Lenovo tablet which only came out last year doesn’t even have a filter. It just dims or turns things black and white which is fucking useless if I’m looking to read a comic or something.
Blue light doesn’t damage the eyes unless there is a burning amount of it (or a burning amount of UV), but people with bad eye focus may find it more straining to read things in blue due to the greater light scatter of the color. The solution is wear your reading glasses, I guess.
What really strains the eyes is focusing on close up objects for hours on end. American eye doctors everywhere have the 30/30/30 rule (every 30 minutes, look at something 30ft away for 30 seconds) as a “let your eye muscles relax for a bit” exercise for those of you always working on something up close.
That said, night filters are good just to help with your circadian rhythm, since the brain looks for a persistent abundance of a particular chunk of blue wavelength to determine “daytime”.
Yeah if your desk is stuck just in one position that’s obviously going to be bad. Most ‘standing’ desks are actually height adjustable. You can spend some time standing some time sitting. But maybe even more important, you can adjust the desk to the right height rather than just adjusting your chair.
I always thought the point of standing desks was, that you could periodically switch between standing and sitting. That should be at least somewhat beneficial right?
No, the main point of standing desk is that whoever has one talks about them all day, every day. At least, that was my experience 10-15 years ago, which was the last time I spent in an office.
I called my standing desk a dancing desk. Didn’t just stand there. I don’t have one now we are back in the office though, some people do but they are all short - I’m taller and it seems too odd to be looking into everyone’s workspace.
Standing desks - stationary standing is just as bad as stationary sitting.
Blue light filter stuff - it’s my understanding that there’s no evidence that blue light causes eye strain.
The blue light filters are hilarious because most devices already support night mode

The software you’re probably thinking of is f.lux
They are not the same thing
Blue light filters can still be nice at night right? As the blue light can keep you awake.
I find it easier on my eyes when its 3am and i am still scrolling.

Standing alternating with sitting doing desk work does alleviate some tension and probably thrombosis. I won’t say a lot, but it does help.
I’ve definitely noticed reduced eye strain with using blue light filters.
You can at least move a bit more when standing at the desk. Also, my past boss was recommended one due to back issues by his doctor at one point

It really isn’t that much better, instead we should be periodically stretching or exercising
Blue light filters may not help with eye strain, but I’ve definitely benefited from them for circadian rhythm reasons.

But how else can you easily assert dominance over the peasants?
