Blue light is very, very bad.

what is “assuefation” supposed to mean?

oh wait
—
assuefa*c*tion
assuefaction (ˌæswɪˈfækʃən)
n
the condition of being or becoming familiar with or used to something
—
merriam webster also says it is obsolete

come on - obsolete word, plus mis-spelled - - did anyone else know that?

It’s a fact that Blue light can be dangerous for Retina,that depends about intensity and concentration of the emission

So, red, green, white, or yellow light in high intensity and concentration ist absolutely harmless to look into?

Poison is in everything, and no thing is without poison. The dosage makes it either a poison or a remedy.

It’s one of those nasty science problems where the tool used to observe biological tissue changes what’s observed.

… It is now well understood that such light doses, and in some cases any light at all, can negatively affect sample fitness and viability.

This phenomenon, typically referred to as photodamage or phototoxicity, is a widely observed but rarely reported effect wherein researchers unwittingly change their sample simply by observing it. The extent to which these changes have affected the interpretation of imaging experiments is difficult to assess. However, as microscopy methods for studying living specimens are evolving rapidly and becoming increasingly in-demand, the time is right for developers and biologists to seek a more quantitative understanding of the effects of light on samples.

Sarcasm not needed,

Much important is the assuefation that people have for the artificial light.
You will want an ever stronger light

Dude, we LIVE on sarcasm, it is what keeps the gun out of our mouths for another week.

Guys, no political or controversial topics are allowed here on BLF. I’m sure disco is one of them.

Try photography, the light just after sunset is called the blue hour for a reason.

“The team of researchers used specially designed lighting on mice in order to test how different wavelengths affected sleep patterns. Blue light proved less disruptive to mice’s sleep than yellow light of the same brightness, according to the researchers.”

but wait, mice are nocturnal.
They want to sleep during the (blue light) day. At night, when mice are active, it makes sense that warm light would help them stay awake.

Good observation! :+1: :+1:

These kinds of articles are so misleading especially for the vast majority of the population that don’t apply critical thinking to what they read.

Btw, I really need to thank this post. For the past few days I’ve been wondering why my eyes were strained so bad in the evening. Then this post popped up and triggered me to check my night light settings on my PC and that’s when I realized a recent update caused the night light to reset to off. I just turned nigh light back on and my eye strain is gone pretty much immediately! For those affected by eye strain in the evening, try turning on nigh light or night shift. It really works! Blue light really is bad in the evening!

Another article That explain how high peak of Blue present
on many emitters(also warm and neutral) make inhibition of melatonine and
then sleep problems on night when Leds are more used…

Yep. But remember the free market in ideas is at work. Industry finds it far more profitable to produce blue-white emitting LEDs than to go to the trouble of designing and producing those same basic emitters with a complex and pricey phosphor coating to intercept that blue and make the output warmer. Same reasoning works for flashlight makers — cool blue-white is cheaper.

Not to mention the market disruption that will be caused when those basic blue-white emitting products are displaced by the newer violet-emitting LEDs. There’s a real scramble going on to fight against the medical advice.

So we are getting more violet light to avoid blue light? sound like its a good idea leading to a possible worst situation. UV is the worst for retina.
