f.lux author here. I'm pasting parts of the 458 page PDF into Google Translate.
The recommendations look very good, and don't particularly match the Yahoo article.
1. They recommend IEEE 1789 as a flicker standard for Europe, which is fantastic, as it covers lower levels of stroboscopic flicker that other standards have missed. (e.g., typical 120Hz flicker from direct-wire TLEDs)
2. They re-state the "acute" hazard from extremely bright LEDs, while urging some caution on "chronic exposure" to lower light levels. Suggest that some automotive lights could be a problem since they have high luminance. Urge more research on progression of macular degeneration and chronic exposure. The question about acute levels refers to a paper by Hunter [2012]. Nobody is saying that screens or residential lights pose a new problem.
3. Circadian recommendations are solid - more light during the day, and reduce light around 480nm at night. Pregnant women and children may have lower thresholds.
4. Say most ophthalmic lenses filtering blue light don't do very much, and specialized ones (you'd say very orange or red) are required for circadian effects.
- thinkling 7y ago> "Nobody is saying that screens or residential lights pose a new problem." This right here is the key for most people. Thanks for f.lux, by the way, have been running it for years!
- pcdoodle 7y agoRespect. Love your software.
- chrisfinne 7y agof.lux changed my life. Always thought I was just a night person. After decades of late-night coding, f.lux educated me about blue light and allowed me to rejoin the living.
- hnick 7y agoWhen I changed ISPs I also changed my modem, which is in the closet in our master bedroom. It's brighter than a disco so I bought some light dimmer stickers. It's still too bright so once I remember where I put them, I'm going to add another layer. It's ridiculous. The only upside is that they are green instead of blue, thankfully.
- knodi123 7y agointerestingly, the human eye is most sensitive to green light, in the sense of perceived-brightness-per-lumen.
- hnick 7y agoI didn't know that! Maybe that's why it's so annoying. My reference to blue was the common belief (fact?) that blue light messes with wakefulness hormones and isn't a good idea around bedtime (hence f.lux).
- londons_explore 7y agoNotably, while green LED's exist, we haven't yet managed to make an efficient green LED. If we had, then illuminating streets etc. with green LED's would save a lot of electricity for the same perceived brightness.
- eveningcoffee 7y agoIt is good then that we have not. Green light is the most ugliest kind in my opinion.
- londons_explore 7y agoA lumen is already a measure of perceived brightness. You can have a 10 watt UV light, but you can't have a 10 lumen UV light for example.
- knodi123 7y agooops, I meant radiant flux instead of lumens.
- simcop2387 7y agoBlack car touch up paint is what I usually use. Either that or nail polish.
- eecsninja 7y agoI had a travel plug adapter (for conversion between US/UK/EU-style) that had a bright blue LED on it to indicate power. I don't know who thought the choice of blue was a good idea, because as a travel adapter, it would be plugged into the hotel room where the user would be sleeping. /facepalm I ended up taping a piece of paper over the LED.
- justasitsounds 7y agoI came here to grumble about exactly this (edit: 'I')
- sarego 7y agoI just installed f.lux. It is almost midnight here. As soon as it installed and my screen tuned almost yellow I can immediately feel the strain on my eyes disappear and replaced with a coolness. This is incredible software. I will probably use this the rest of my life.Thank you!
- copperx 7y agoI hope f.lux becomes irrelevant once dark mode becomes the standard in all devices. If the web catches on and if our screens become OLED (or use any technology where dark pixels aren't illuminated), then "night mode" will be seen as a crazy hack.
- Tempest1981 7y agoHow do you like viewing maps in dark mode? I tried Apple's Maps app on macOS, and it felt weird -- like navigating at night. Otherwise, dark mode seems good.
- WorldMaker 7y ago"Night mode" is still useful with Dark Mode. In most applications Dark Mode still uses plenty blues and greens for accent colors and often strong whites for text colors. Even if fewer overall pixels are dedicated to those colors, it's still useful to color shift them away from blue in the evenings.
- blencdr 7y agoThank you ! f.lux is a blessing, i use it since a few years and if it happens to use a computer on the evening without it I feel assaulted with agressive blue light.
- vbuwivbiu 7y agoanother thankyou for f.lux here!
- sigi45 7y agoDo you have by any chance a proper spectrometer? After all you developed f.lux? Would you be able to share images on what the real difference is with and without f.lux? And also the ophthalmic lenses? I just got some so i'm quite curious :)
- equalunique 7y ago>4. Say most ophthalmic lenses filtering blue light don't do very much, and specialized ones (you'd say very orange or red) are required for circadian effects. I have had years of success averting personal blue-light issues using what probably falls into the "specialized" lenses category: Uvex S1933X glasses. They came in a 3-pack on Amazon for around $25. The pairs are next to my bed, on my desk, and in my backpack. Inexpensive enough to where I won't loose sleep over breaking a pair. Good not just for device screens, but also for the annoying bright blue power buttons/indicators on just about every other peripheral.
- mleonhard 7y agoI just wish the Uvex glasses were more comfortable.
