I’m not sure “lumens” is a good measure for this topic. After all, UV is zero lumens but damages your eyes.

It may be the brightness of the LED, I’m convinced (if this is anything). If that is the case, WE ARE ALL SCREWED…but we ain’t changin’ a thang!!!

There are just some sacrifices that modern life does not allow us to make. And nothing we can do can offset “light cancer” if indeed it is a thing (e. g. we aren’t going to stop driving due to accidents).

Wrong. Switching to luminaries that don’t suppress melatonin is an obvious way to reduce the impact.

Google wants to be your friend, you know.

… reduced melatonin production has been reported among night-shift workers [10–12]. Consequently, the suppression of melatonin secretion by exposure to light during nighttime hours is surmised to be the main biological mechanism in the relationship between breast cancer and night work.Feb 6, 2018

“we can’t do anything about…” means just “it’s the way it always was – never change a running system”. Kind of ok from some point of view, but imo we must continuously seek the best solutions. We’re clever humans.

Yes, we are intelligent humans.But we are also 8 billion and some greedy and destructive, where the only goal is accumulate profit.Looking how the pluvial forest has been reduced and the pollution of water,air,earth with this stupid consumerist system and globalizzation
I’m not so optimistic

Nope. How are you going to get everyone else to not use, say, LED headlights on their vehicles? How about indoor lighting, more “cancer lighting?” You can’t do it, even if you give up your angry blue throwers. You see?

I can see aftermarket “blue-blocker” filters becoming available to slip over indoor lights, etc.

Would glasses with red lenses count as a good filter?

or is it the other way, you want Blue lense to filter blue light?

The last several nights, I’ve turned my Chromebook, Mac Book Pro, Tablet, and phone on “night mode” and adjusted the sensitivity toward extreme warm. Now, I’m not only adjusted, but I immediately felt the muscles in the back of my eyes relax. No joke.

I don’t yet think that blue light causes cancer, but I’m man enough to admit when I’m wrong. Ocular problems from blue light are, on the other hand, much more believable. What I’m saying is, I’m interested now and want to research this more.

You can’t do it

You can reduce your total exposure. You can wear driving glasses with a blue-blocking tint. You can put a Rosco amber theatrical filter gel over your monitor or television.
And you can choose your own indoor lighting to reduce the exposure to blue-containing light for late evening hours.
You can be aware when your city puts in LED street lighting, for example: https://www.google.com/search?q=europe+%22blue+light%22+standards

Harvard has updated their early review of the issue: https://www.health.harvard.edu/staying-healthy/blue-light-has-a-dark-side

I actually kinda miss those 0CRI pinkish merthiolate-colored streetlights from a ways back.

Couldn’t tell blue from green from black…

Not sure what causes cancer in nightshifters (if studies are right). Maybe breaking the natural cycle is the culprit, be it melatonin per se or just the missing sleep caused by its supression. But there are quite some studies by now.

No night mode in my old Android devices, but there’s an app. I got so used to it that I never switch it off. My Win10 laptop also is constantly in night mode, but mainly because the display is quite blueish.

Not missing CW.

Definitely not bogus. Our bodies are very sensitive to certain wavelengths of light. The study focused on the bluer side of the spectrum, like 6500k and up. It is proven that cooler light can trick our bodies into thinking it’s daytime-which can disrupt our sleep-wake cycle or circadian rhythm, which when that is disrupted causes all kinds of other issues, including systemic ailments. The prevalence of LED streetlights with the cooler light caused issues for drivers (excessive glare and also sleep difficulty) so they had to switch them to warmer light, closer to 4000k and lower. Same with your mobile phone, which emits blue light (especially for LCD’s). Now phones have a mode that makes the screen warmer at certain times. Same with my laptop pc.

i would be highly dubious that a flashlight can make enough blue light, long enough, to make any difference.
or a cell phone screen.

how could that ever be proved?

cell phones and pcs have ‘night mode’ only because
a. it is free and
b. it is also FOM fad of the moment

there
i said it
hmph

wouldn;t THE SUN have 100000 times more ‘blue light’ than any puny screen or flashlight?
