    • The other day, @Dracula and I were chatting about how we wished that Cake had

      Dark Mode

      I have it set to “on” with Twitter and my eyeballs greatly appreciate it. Plus, per Drac, Dark Mode uses less battery life due to less screen pixels to illuminate.

      So on a related note, CNET came out with a review of something called blue light-blocking glasses that are supposed to provide similar benefits to your eyeballs. There is even a pair where you can decide how much blocking you want on a zero to 100 scale. I’ve never heard of them before and the obvious commission-based links to product make the article feel like sponsored content. But, I’m also interested in new wearable tech. Or “de-tech(?)”.

    • Funny you mention it! I just was playing around with chrome://flags/ and found #enable-force-dark changes your entire Chrome experience to Dark! But, be careful as it's not really fully tested.. may break other web sites.

      Here is how Cake looks in Black:

    • I am always conflicted about the dark mode. I usually try it on sites
      then end up switching back. White text on black seems to throw me off.
      Such a great example of how user experiences should be customizable. How
      we consume exeperiences should be personal! The glasses look interesting
      as well.

    • I definitely ought to check out some of those glasses, I spend most of my awake hours staring at screens.. and it really hurts at the end of some long days. Thank you @StephenL

    • Yeah, Dark mode is cool. We have it on ADVrider and SmugMug. Nice find on the force dark mode in Chrome, Dracula. I’ve always thought photos look better in dark mode. It works on my laptop but doesn’t seem to be available on my iPad.

      As for blue light blocking glasses, my opinion is they’re like vitamin C supplements. They do neither good nor harm. But glasses that block UV in the sun are important.

    • Funny, I've always liked photos against a light background - but that orchid photo does look good against black.

      My eyes find it easier (more comfortable) to read dark text against a white background.

    • @Chris beat me to it!

      Folks used to live andwork out of doors.

      Guess what color the light was out of doors from that huge blue sky overhead?

      There is a strong relationship between lattitude, working out of doors and cataract formation in high intensity sunlight, but more likely the UV light in sunlight, is thought to be the major contributing factor. Farmers and sailors and other out of door workers in the tropics do have higher rates of cataract formation, as well as skin cancer formation and even macular degeneration.. I am not aware that blue light is a significant concern however.

      Most glass lenses effectively block UV light, but one needs to see the transmission graphs of the specific lenses to be certain. Plastic lenses are a bit more variable re UV transmission.

      Folks have been trying to sell yellow lenses ( blue blocking ) for years. Call me less than wholly convinced. Years ago the pitch was they helped folks with cataracts see "better". but "better" was rarely defined other than "better". Now they pitch blue blockers to sleep better due to the blue light from computer and phone screens.

      The way to sleep better is to step away from the computer or phone screen, get some real exercise, and turn in early with the lights off.

      Great link @Chris, basically stating what I've believed for a long time.

      One thing I do find when using computer screens and wearing bifocals - one needs to keep their monitor low enough that one can look down through their bifocals and see the screen - if the monitor is too high, say at eye height or higher, then one must extend their neck, raise their chin, to get their bifocal high enough to help focus the screen and this sustained extension of the neck can really lead to a stiff neck or even headaches.

      If one has dry eyes, sustained reading with suppression of blinking, can aggravate dry eyes. Blink more often, drink more water, or even use artificial tears if needed. Drinking more water often really helps a lot, but it is not intuitive for many folks to drink more water for dry stiinging eyes...

      Blue light, well, it is blue....

    • I have used white text on a black screen on my Kindle App on my iPads for many years.

      Occaisionally if I am in the bright sun, I prefer black on white text, but not usually.

    • I think the idea behind UV filtering glasses was more applicable to the monitors of yore, that had Cathode Ray Tubes bombarding their screen with electrons to lit up the screen. Those emitted quite a bunch of radiations of different wavelengths, and indeed some protection was best for humans staring into them for too long..

      .. these days, the monitors are all LCD, LED, etc.. do not emit the levels of radiation of the old CRT. So yes, perhaps a bit of snake oil is involved...

    • Yup works for me. Thanks for the tip BTW. Before this chrome was in dark mode already for me but only the toolbar and settings, web pages were still white. Now everything is dark 👍

    • I happened to get the blue filters in my glasses a couple of years ago when Costco was touting it as a value-added feature and not charging for it. The only difference I have noticed is that some people look at me funny and say, “Oooo, are your glasses purple inside?” Hahaha. They think it is some kind of cosmetic thing, kind of like colored contact lenses. 🤓😎 I haven’t noticed any other differences at all. (I think it is actually some kind of blue/purple reflective wash rather than an actual filter—it does not alter colors as I see them at all.)

    • I’ve looked into blue blockers but never bought a pair. There’s no question that the light from my laptop screen has an effect on me - it wakes me up and makes it harder for me to sleep if I’m using it late. I never had that from a CRT screen, and it’s less of an issue with my flat screen TV, too, maybe because it’s farther away. I don’t use my phone much at home so I’ve no idea what impact it has. So I wanted to get the blue blockers for use only with my laptop to see if it would make a difference.. but I never bought them. The scuttlebut among Amazon reviewers a few years ago was that only the yellow tinted ones worked. An optometrist told me I should get polarizing lenses instead, but I was skeptical about that.

    • Among photographic print labs, there has always been a critical unknown: will your customers unwrap their prints under indoor household lighting (making the prints look yellow), at work under fluorescent lights (making them look green), or indoors in the day with no lights on (making the prints look blue).

      You will get returns and bad reviews no matter which bet you make.

      Now photographers have the same dilemma because of things like Apple's Night Mode or f.lux to cut the blue emitted from your screen with the idea you'll sleep better — making photos look yellow.

      I had yellow tinted computer glasses for awhile, but now I prefer the ideas of f.lux.

    • Hahaha, I thought about my confusing wording and probably even science after I posted that. What I was thinking is how much reflected light changes the color of things. You photograph someone in a lush, green setting and they take on a green tint that is hard to remove from their skin and clothes without changing the tint of the foliage. Good thing they’re not transparent like jello.

    • I photographed a bride on a golf putting green once - really bad choice - her white dress looked very green indeed, even with magenta filtration. Nothing lilke neutral backgrounds for color balance.

    • I have photographed brides in every imaginable setting and damn that dress can be hard to keep white. On one side it picks up red from the rocks, on another it picks up green from the river. In broken light, which I like to shoot in, it has patches of yellow where it catches the sun and blue in patches of shade.

    • Yup!

      Did folks experience this nearly as much with Kodachrome, I wonder? The light and its reflections didn't change. Maybe it was just shooting at ISO 25.??

      I always have wished digital camera manufactuers made digital cameras with ISOs that could be lowered down to 5 or 10, or even 2
