Is a blue setup harmful?

Crypt1c

So its well known that the blue light from screens are more harmful to your eyes than others. Does the same thing applies to lights from things like your keyboard?

not more then your monitor, or your phone, or the sun or almost anything blue

I spent $2500 on building my PC and all i do with it is play no games atm & watch anime at 1080p(finally) watch YT and write essays...  nothing, it just sits there collecting dust...

Nope. If anything, dim-ish blue lighting is good when you use monitor in dark environment. It stresses eyes much less than other colored lights, except warm white or pale yellow.

If you use your computer at night/in the dark, avoid blue light. its not dangerous to your eyes, but it messes with your melatonin levels and can cause sleep issues.

 

https://justgetflux.com can help  with reducing blue light from your monitor. you can also get glasses that block blue light.

Blue light in general is bad for sleep, but computer screens in general are the worst offender. Blue keyboard lighting isn't quite as bad ( there just isn't as much light), and you also aren't constantly looking at it. Generally it is best to avoid computers from 2 hours before you go to sleep (but I can't say I do that personaly). However, using a utility like f.lux will remove most of that blue light for you. Anyway, if you can change or lower the blue of the keyboard it will probably help, but probably won't make a huge difference

Thanks.

 

I've previously read a fair bit (mostly via New Scientist) on the subject of external factors that can interrupt natural sleep patterns, but the OP merely said they were "harmful to your eyes" which is a bit vague. Hence my confusion.

 

The first link mentions artificial light in the general context of interrupting the circadian cycle, with blue light being the worst offender. But it also mentions simply working night shifts or being a night owl in the same way, and that exposure to light of any sort is disruptive to your sleep (and overall well-being) if used at the wrong times. It also neglects to link any sort of reference despite their being "study after study", which is a bit of shame.

 

The second link appears to be an advert for Gunnar eyewear. Also devoid of any original references.

 

TL;DR I'm unsure is "harmful" is the same thing as more likely to be disruptive to sleeping patterns if used late at night.

Well, there is a lot of concern about actual damage being done to the eyes, but that's still not proven.  Eye fatigue and pain is a well known effect of too much blue light exposure though.

 

As for the second link, it is true that Gunnar is being mentioned twice, but they also mention (and link to) 2 apps that filter out blue light.  Also, it's still an article from the Washington State University so they'd have to mention if it is in fact paid for by Gunnar.

The single most potent source of blue light is the sun, so I assume you mean artificial blue light (when used extensively). I'm pretty sure being outside all day doesn't give eye fatigue and pain (unless you're looking at the sun - lolz). So, this pretty much comes back to excessive use of electronic screens in general.

 

If blue light negatively impacts your sleeping cycle at night, it's fair to assume it's just as important to promote wakefulness and positive mood during the day. Also, I didn't mean that your link WSU was literally an advert, but without any medical/scientific reference the information cannot be confirmed. So, all that's left is a recommendation for some apps and glasses.

http://www.allaboutvision.com/cvs/blue-light.htm

 

The 2nd link does of course highlight some of the concerns you mention, but also points out that research isn't conclusive; and it quite rightly highlights why blue light is also vital for your health at the the correct time of day.

It's well documented that some blue light exposure is essential for good health. Research has shown that high-energy visible light boosts alertness, helps memory and cognitive function and elevates mood.

In fact, something called light therapy is used to treat seasonal affective disorder (SAD) — a type of depression that's related to changes in seasons, with symptoms usually beginning in the fall and continuing through winter. The light sources for this therapy emit bright white light that contains a significant amount of HEV blue light rays.

Also, blue light is very important in regulating circadian rhythm — the body's natural wakefulness and sleep cycle. Exposure to blue light during daytime hours helps maintain a healthful circadian rhythm. But too much blue light late at night (reading a novel on a tablet computer or e-reader at bedtime, for example) can disrupt this cycle, potentially causing sleepless nights and daytime fatigue.

 

 

Still, the OP was asking about keyboard LEDS. So, getting back to the topic at hand - I'm fairly sure blue keyboard lights aren't going to screw up your eyes, unless your keyboard is tied to your face all night every night. This of course will also obstruct your vision somewhat anyway.

Keyboard lights are not very bright and should not affect you eyes that much, Things like monitors or phones with brighter screens or are closer to your face will.

Blue light isn't harmful, it just is what we recognise as daylight. 

 

If you're not getting enough sleep, turning off bluelight or removing it from the visible spectrum on show from your monitor can help, but it isn't "harmful."

the harm from blue light isn't "harming your eyes"
its more that blue wavelengths can throw the chemicals in the body/brain meaning that sleep can be disrupted

it's why they use things like blue lights in places close to the poles, to combat S.A.D. (seasonal affected depression) where in the winter months the lack of sunshine leads to depression

and the reverse is true, too much blue light gets the body all geared up (because it thinks there is sunshine) to not sleep, because it thinks the sun is up


if it is eye strain harm you want to reduce, soft lighting filling the space behind a monitor
it your worried about the lights on your keyboard, dont, unless you have trouble sleeping, and the computer is in your room, kill the blue lights, it can affect more than you might think,)

also dont listen to people that post things like this

 

"Nope. If anything, dim-ish blue lighting is good when you use monitor in dark environment. It stresses eyes much less than other colored lights, except warm white or pale yellow." 

because it isn't true, and is laughable 
(fyi, warm white/pale yellow is obtained by REMOVING the blue spectrum, and the best light to reduce eye strain is red (not for reading etc, but for giving vision to thing without causes eye strain) that's part of the reason it is used in many darkened environments (that and you dont ruin your night vision going from dark, to a red light lit room, where green or blue (and mixes of all three) will

So it's well known that cats are efficient predators. Does that mean that if I adopt a kitten my life will be in danger? 

 

It's also well known that overreacting causes paranoia. Does that mean that if I make a mountain out of a molehill, I'll end up in a mental institution?

Do you constantly stare at your keyboard, if not then no, heck even staring at blue light from modern leds won't do anything worse than eye strain

Shouldn't be.

 

And as far as I know, the blue light just keeps you awake, I don't remember hearing that it causes any actual damage. If it does, I'm screwed, my keyboard is blue, my usb hub has a blue led on it, my taskbar is blue, my gpu glows blue, and plenty more xD
