The screen hurt your eyes?

[bug]

I don't see how anyone can disagree with bug's assertion that blue isn't close to white and neither is any color because white isn't a narrow range of frequencies it's the entire gamut of visible electromagnetic radiation. I don't see what 'brightness' has to do with that assertion either, amplitude is independent of frequency.

There's a simple explanation for that: we live in a world where physics is just someone's opinion.

I guess blue light is the new gluten. Find a minor problem with it and all of a sudden, the whole world is affected...

don't know about all that mess with gluten or lactose hype...
PS once YT have recommended me video when some doctor said that all that blue light hurt is not that bad as it's hyped...
personal observations: of course, if you work on pc at night shift, it's very helpful to put monitor into warm color palette. helps A LOT.

Well your opinion of physics, is certainly just yours. Luckily most people here know better.

hey i may let the blue light thing go, but not the lactose, oh it's real, believe me, just ask my toilet if i ever have that thing.

Oh, it's real alright (celiac disease, it affects like 1% of the population, but I imagine it sucks big time to be in that 1%). But while it affects only a very small part of the population, all of a sudden everybody is staying away from gluten, just because they've heard something bad about it which they did not even try to understand.
Blue light is pretty much the same story all over again.

Typically the closer the lighting is to actual sunlight spectrum the better. Some people are more sensitive to this than others.

I picked up some 95 cri led bulbs by Philips at Home Depot. Seem good. No buzzing good dimming as for cri I don’t have instruments to verify 95 cri though.

Yes, you can do some simple testing. Various kinds of red, orange or yellow food (meat, tomatos, chili, sauces) will look different under a poor CRI lamp. Less tasty, greyish/greenish/darker. That's true even if you perceive the good and the bad lamp as having the same light colour and intensity (metamerism).

bulb temp matters. Especially for people with color deficiencies. 5000k daylight bulbs can appear blueish and harsh. 3000k-4000k is a better range

Same for people with perfect colour vision.

Blue light has a dark side - Harvard Health

Light at night is bad for your health, and exposure to blue light emitted by electronics and energy-efficient lightbulbs may be especially so. ...

Regarding the perception of flicker: peripheral vision is more sensitive to it than central vision - it seems that rods react to light faster than cones. I could clearly see it on the 50 Hz CRT with the corner of my eye but not when staring directly into the screen.

I'm not sure what you think you have found, but that article proves my point (blue light is only to be avoided at night), not yours (blue light is harmful and somehow "closest" to white):

Blue wavelengths—which are beneficial during daylight hours because they boost attention, reaction times, and mood—seem to be the most disruptive at night. And the proliferation of electronics with screens, as well as energy-efficient lighting, is increasing our exposure to blue wavelengths, especially after sundown.

PS I thought you were done answering to stupid, old me.

You never said that. You generally said that it’s nonsense like gluten (which is another nonsense by you, gluten has definitely problems) and other things and denied everything I said about it. Again: if you think bright light is that great, go and watch the sun, let’s see how you hold up. You’re making 0 sense, friend. Same with any other bright light source, inb4 you think it’s only about the sun. I was frequently annoyed by cars using Xenon headlamps for example, while normal headlamps were perfectly fine unless on the wrong setting and directly shining into my eyes.

Ok, so there's a lot of lies and shenanigans around "blue light" that's being used by some companies to trick gullible people into buying their crappy products, like "blue light filter gaming glasses" that are simply regular yellow tinted glasses being sold for $80 or "all-new high end special flicker-free lightbulbs" that are just regular bulbs with a bigger filter cap, that's it. It's the eco wind/solar powered dryer that was a clothesline all over again.

There's some truth to it but I'd dare to say 80% of things you see on the internet about blue light is just bs made up by corporations trying to sell something. I don't like LED screens, lightbulbs (poor CRI) or staring at a ridiculously bright monitor but it's not a HUGE problem at least for me.

Blue Light and Your Eyes - Prevent Blindness

Sunlight is made up of red, orange, yellow, green, blue, indigo and violet light. When combined, it becomes the white light we see. Each of these has a

Eazen: You're talking about something that's exclusive to LED lights as if its a permanent phenomenon of all lighting, when its not.
I have some RGB light strips here, as well as WRGB - the RGB ones use blue to simulate white while the WRGB have dedicated white LED's to avoid the blue issue.


Not all LED's suffer from the blue-white issue, and other types of lighting don't do it at all.
Various monitor technologies like OLED dont need LED backlighting, and therefore avoid the issue entirely

One key point that came up in a thread about light globes here on TPU is that the colour of your walls and the material made from, alters how lighting works MASSIVELY.
Someone with wood or brick walls will have far less issues since the light isnt reflected - while reflective white paint walls are going to make that flickery blue mess come at you from all angles and require far more backlighting to overcome.

Yeah, I don't think he understands how it works. He seems to assume all is fine because he picked a high-refresh monitor.

seriously, backlight flicker is better on high refresh screens so that genuinely can help people - not everyones eyestrain is caused by the same trigger (blue light, backlight flicker, motion smearing, background lighting, etc)

No, I was talking generally. Just read all my comments here. Edit: I don’t think it’s exclusive to LED lights. Blue light is one of (or part of) the brightest lights, and bright light isn’t good for the eyes, someone who looks into bright lights a lot, will have his eyes age terribly or permanently damage them.

brightness is not determined by colour

you cant simplify it to blue is bright, bright is bad, therefore blue is bad. There is truth to what you're saying, but it's oversimplified to the point of being incorrect.

What color is the sun again that's pretty bright I once heard you're not supposed to look at that either

I didn’t simplify anything, click the link I provided. You’re very late to this discussion.

What color is the sun again that's pretty bright I once heard you're not supposed to look at that either

The sun is a mixture of multiple colors, maybe click the link I provided.

Seems people are just browsing through this discussion eager to be smart, instead of reading and regarding the points that were already made.

In other words, this discussion is over, I don’t need to prove the same thing over and over again. Have fun, I have enough of this.

White. Our sun is a white dwarf.

It's actually greenish: https://en.wikipedia.org/wiki/Sunlight#Composition_and_power (notice the hump is the visible spectrum)
Also notice how the spectrum is altered a little by the atmosphere.
