I work in the communications field. Multi-mode fiber uses LED light (usually red) to transmit data over the fiber optic cable. There are warnings about looking directly into the end of the fiber connections and the possibility of invisible light being a risk of eye damage. It's the invisible light that is the most damaging to the eye.
That warning is not exacly related to LEDs. Fiber optics often uses infrared light, which is invisible, but it can still burn. Because it is invisible, you are not alarmed that the cable is active and accidents happen. Also it does not trigger the blink/look away reflex like visible light.
Most multi-mode fiber equipment in the 90s used LED to transmitted light, over using Laser Diode light used by single mode. I've seen switches in the 90s (with white LED light) that had warnings right above the ST about looking directly at the light. Nowadays, companies like Cisco use red laser diodes to transmit data. Yeah, the IR light is what is the most dangerous and as Bryan says in his video, it is being emitted by LED screens.
Gamevet IR is the most beneficial part of the entire electromagnetic spectrum, not the most dangerous(that label should go to Gamma and X rays). Looking directly at a harsh laser diode is what's bad for your eyes irrespective of the wavelength emitted.

Thanks for the info, I had never considered it before or understood why a monitor would be advertised as low blue light for a reduction in eye strain. Got me thinking now!
WLED's are terrible for your eyes. They produce enough blue light to cause damage, as well as trigger the intrinsically photosensitive retinal ganglion cells to stop melatonin secretion. That disrupts circadian rhythms as well as increases cancer risk, since melatonin is an essential antioxidant. WLED's and CFL's are both pretty bad for you, and you're better off using incandescent bulbs for indoor lighting. If you light to appropriate levels, it's actually very inexpensive to use incandescents, and they have a 100 CRI as well as no metamerism. The trend of replacing high pressure sodium street lights with WLED's is another dangerous and stupid one. Since blue light scatters most(which is why the sky is blue), it makes driving in fog or rain more dangerous, as well as producing veiling luminance and glare.

This is an issue with pretty much all panels (phones, tablets, etc.). In the day you should be fine, as usually how it's set is fine for day. But at night. That's when your eyes will get strained and what not, much more when you don't have natural light which is more of a blue haze (like a pure white) So the solution is usually something like F.lux (which changes the screen to be more orange, which really eases the strain on your eyes. Or something with a Amber / Orange filter glasses, something like Gunnar Optics.
Blue light also can trick your brain into thinking that the light is brighter than it actually is. This in tern will trick your brain into staying into day mode for longer making it harder to go to sleep. You will see blue lighting used in dark places you need to see but don't want light to bleed into the sounding area - for example when lighting up parts of backstage, blue lighting is used so that walking lights don't conflict with the stage lighting.
LEDs are naturally in the infrared/red spectrum, its where they're most efficient. My eyes have actually gotten better in the past 6 years, used to wear glasses in high school and quit all throughout college and thereafter. Switched to ALL LEDs, monitors, phone, bulbs, etc. It's a matter of taking care of your eyes, i always turn brightness all the way down and switch to a warmer color tint on all screens, always have a light on and never read in pitch black or in super bright light.
I have an LED lamp that can cycle between "red" "blue" and "white" colors....Even though the LED bulb doesn't change is "red" setting better for my eyes? what about the "blue" color and "white" (regular light color) settings? I would sincerely appreciate an answer to this..thank you
Those weird lights tend to give me a headache ;( Also i had 20/20 sight before as well, but in a span for about 1.5 years or less i don't have a good far vision anymore feelsbadman.
With almost all flat screen TV's going to L.E.D it will be hard to get away from them . I have also have an L.E.D monitor , and I agree with the feeling of eye strain , thanks for the video .
Hm, ill have to try switching between my led monitor and my other one, but I haven't noticed a difference, then again usually you don't notice differences in things unless you compare it.
You can try lowering the blues in the OSD. Also try to lower the brightness, that can help sometimes. Some LED monitors have a nasty flicker, you might be sensitive to that.
I have a challenge for the scientist and inventors for new stuff and that is: " create pure white light source that can even heal our eyes and if you can put this into the monitors and TV backlight technology, home light bulbs..... then i can call you the greatest inventor and world best scientist !!!!" THANKS for sharing the info about this blue LED's that we see in it every day and telling us all for the negative impact that they have on our eyes, so for that reason i dear the scientist or anyone that can find the material so it could produce the perfect white light with minimal impact on our eyes and added into the light sources that we are using every day for sake of everyone's health. ;)
This may be a seriously bad question, but, do lcd displays have the same effect as the led screens we are all using. And if so, should we all go out and buy lcd monitors to better our eyesight.
Most of them do use flux it will help you, don't worry about the yellow color at first your eyes will auto adjust, start from low and go higher little by little.
I have a similar symptom as you. So, did you find alternative solutions? CCFL monitors are discontinued these days. What are you using as your main computer monitors, what about your prognosis ?
I have an old plasma tv, and that’s the only tv I can watch for longer than 30 minutes. All LED TVs make me feel “off”. I’m angry that LED is our only option now.
I left my computer on while I went out to eat dinner for two ours and I guess the queque has somehow brought me here. I have no idea what is happening in the video but your accent is making it alright. I subbed.
After 15-20 minutes after looking at Led backlit screen, phone or being in a room with led bulbs or lamps i get headaches, horrible eyestrain, dry eyes, double vision, motion sicknesss, weakness in the whole body, losing the ability to mentally focus, this only happens to me from led lightning can stare at my ccfl and crt all day without issues.
The energy star bulbs make cold light which wrecks havoc I suffer from major depression severe anxiety etc. I like incandescent three way bulbs. transparent bulbs and color bulbs. 25 watt transparent incandescent make more light than a curly cue flurecent 100 watt equivalent. I do notice I don't expiance road rage at night from halogen headlights. led headlights I have to stop in the road to let led headlights go by because I can't see the road. first generation technology's the inventors got things right the first time.
oh yeah thats right there is the hype and the initial switch from incandecent to LED light bulbs to save energy etc, but those light bulbs hurt my eyes with the pure "white", which thanks to this vid now we know is blue i made it a point to find low lumens light bulbs, and that are the old style, not LEDs, they hurt my eyes so monitors can't be much different if not more direct!
I'll keep using my CCFL monitor for years to come. You can negate the blue light issue of LEDs by changing the colour temperature but, maybe it's just not the same?
@1:45 it gets pretty dramatic lots of articles on the internet about blue light, and how its like government-anti-conspiracy-level type stuff i just want a monitor that doesn't give me eye strain by the way, i got some new led monitors and that night after using them, i had some bad dreams. maybe it was the game i played, left for dead, but maybe there are some psychological/ physiological effects going on with the blue light frequency too
I think the problem was that your blue LED light was using, well, blue LEDs. Blue LEDs emit only blue light, whereas white LEDs emit other colors as well. However, not all white LEDs are equal, in fact there can be massive differences in the spectrum of the light emitted. One should probably seek out LED lights that have a warm white color instead of a cool white as they should give out more green,yellow and red light and less blue. Also many LED lights have a flicker at 100-120Hz, some bulbs flicker a lot, many has a bit of flicker, and a few have no flicker. Some people may be sensitive to that. On the topic of monitors having LED backlights, I think it is less of a problem than in general LED lighting. The LCD panel has red, green and blue subpixels, and thus two thirds of the screen area will have color filters that block blue light. Only the blue subpixels will let blue light through. I guess if one is spending a lot of time looking at a mostly white or blue screen, then it can still be a concern, but most monitors provide a way to set the intensity of the RGB channels separately, so one can always just lower the blue value in the OSD and get a nice reduction in blue light. Oh and some LED backlit monitors flicker too depending on the brightness set, and it can cause eye fatiuge in some people.
Wow! That good stuff to know, Man! A couple months ago I was up late on my laptop and I actually started seeing black spots/smudges! I was kinda spooked cause they would've go away EVEN IN THE DARK! The next day I woke up and they were gone from my eyesight! I haven't seen them for a while now, But i do have to be a bit more careful!
I used to play games on my iPod a years ago and it was the first time I noticed my eye sight becoming worse. After playing a game for nearly 2 hours I started to look outside towards a fence and it was Very blurry. I thought I was going blind so I took a nap that brought my vision back. Ever since then I think my eye sight has becoming worse. I can only see a meter away and then things start to go blurry. I can't see the stars or moon clearly at night. Traffic lights cast a light shadow around them. It used to look sharp, and definite, but now it's like a halo around it. Sometimes I get some type of double vision after long hours.
Garrett we need to raise awareness to the manufacturers guys....this is some serious issue...please take any action to stop them from making leds....i left my job and sitting home unemployed since i worked on screens
i am using one now, and to be honest i cant wait to go back to led... my eyes are killing me with my ccfl :c BUT i do think in my opinion ccfl give more light... thats my opinion thou..
I turned my monitor brightness down and I use low power LEDs for my room light because I found they physically hurt my eyes after extended periods of exposure, so it wouldn't surprise me if there was some science behind it.
Does anyone else have the same symptoms like me from leds ??? After 15-20 minutes after looking at Led backlit screen, phone or being in a room with led bulbs or lamps i get headaches, horrible eyestrain, dry eyes, double vision, motion sicknesss, weakness in the whole body, losing the ability to mentally focus, this only happens to me from led lightning can stare at my ccfl and crt all day without issues.
Kuzma Gameplays N' Music yes buddy i am facing this same issue with all screens only with led...i tried using yellow tinted lenses it helps a bit but not completely....we need to raise the awareness for the same...these manufacturers just think of business and money not our health
Great video! I too use f.lux to try and minimize the straining effect of my monitor (specially in the evenings). Could anyone inform me on what the intro song is? Thanks
Flourescent light is also bad for your eyes. It's been tested by health specialist and opticians it has a very detrimental effect on ppl suffering from glaucoma. So I am assuming it cannot be that good for healthy eyes neither. LED's are in fact not that bad in terms of lightning they produce, when compared to all the other lightning alternatives to the incandescent bulbs LEDs come closest to their gamma curve and is the most natural from the lot. The problem with LEDs and particular the ones used in the monitor displays is that in many cases the companies are using blue rather than pure white leds f.e., even some of the ones that are supposed to be white has that blue peak. Maybe more than some. Gunnar optics aren't actually guaranteed to protect your eyes from the UV light, the visible blue one yeah, but unless they sport a 100% uv protection on them I wouldn't be that sure that they are keeping your eyes safer from the "blue led" light. What is more of a bet to protect your eyes and minimize the risk is glasses made from stuff like trivex that have inherited 100% UV protection. Polycarbonate has it too. Decent sun glasses with 100% uv protection work as well. Other than that you may be able to reduce eye strain, but if you are talking about lowering the risk of long term damage you need to use something that has 100% uv prot, bcs uv isn't in the visible spectrum, at least not in the human one. You could wear tinted shades or spectacles, but without the uv protection you might be just as unprotected as you were without them.
Get a lower frequency LED. It's not the LED but the color of the light. Also that's cyan, not white. White light is the combination of all visible wavelengths. Cheapass white LEDs use a fluorescent phosphor to make yellow to balance out the blue. RGB LEDs are much better for white lights. Use a red/orange LED instead. They exist.
Don't worry people, soon all screens are going to be OLED = Organic Light Emitting Diode. A lot of smart phones already are. en.wikipedia.org/wiki/OLED
Is it still very expensive though? My Cowon S9 has AMOLEDs and that is 4 years old now... Guess it is just too costly to put these in a computer monitor :(
Tech YES City On August 13, 2013, Samsung announced availability of a 55-inch curved OLED TV (model KN55S9C) in the US at a price point of $8999.99. Soon we will see affordable TV's and Monitors. Some manufacturing companies have recently, came up with cheaper ways of manufacturing them.
I remeber I read/heard somewhere that our eyes are more sensitive to blue light. also LEDs direct light more than CCFL or incandescent light bulbs, maybe the strong light is what is causing you the black spots? if you ARE going to be a human test subject, try looking a bit into what the causes the black spots. don't take it the wrong way, but I really hope that you are wrong cause I really LOVE LED's!!! =D

That is awesome! I have the same CPU, GPU, power supply and HDD and man, the performance is fucking awesome. Totally would recommend those part. You will be more than happy.
If your going to buy a H97 motherboard, better to buy a non K processor. Go for a Z97 if you choose to stick with the 4690K for overclocking purposes. But all in all, looks like its gonna be a killer build. Happy building!
Hey Josh, Paul is right... it's either 4690 + H97 Mobo or 4690K + Z97 Mobo. If you want to overclock, and I suggest you do, Gigabyte offer some decent Z boards at that $150 range you want to spend. The PSU isn't the best, non-japanese caps, below average ripple etc and 750w is crazy overkill for the system. Look for something with better quality at 600-650w. The case also has no room for the ASUS DRW, you need an external drive to install Windows from a DVD. Also, get Win 8.1, not 7, all the negativity about it at release just doesn't fly anymore. au.pcpartpicker.com/p/mwvfRB There ya go! $1623 (without external DVD drive). Z97 mobo, better psu, slightly faster RAM, the rest is pretty much the same except... drum roll... and still under $1700... with... a 256gb Crucial Mx100 SSD!
Interesting topic, at night time i run a 5metre RGB LED Strip around my room to give it some light, it can get quite bright so i do lower the intensity, but for me personally ive never really noticed anything different after been exposed to the LEDs for a few hours, even the next morning. Light doesnt affect me as much as sound, could be something
phew! i have old lcd's tvs an laptop, i dont have any led lcd thanks for info, also when cars with led lights crossover me they really blind me off by night obviously , once it almost got me off the road
Folks they are using blue led on all electronics reason,to throw you circadian rhythm,that's what tell your body when to go to sleep. At night instead of feeling sleepy and going to bed you stay up watching tv,with that blue led shining in your eyes or on your laptop. By science it's fact blue light is bad for your eyes,the cars with led lights,when they came out with the flashlight you couldn't look into them because of the intense glow so why they use them for headlights? People think having bright headlights on their car help at night but it doesn't because they only can be so bright,when it rains most the light reflects off the wet road. The halogen is a nice orange glow,it's natural,led is not,our eyes are meant for the sunlight and the moonlight. One way to stop this ,is stop buying the led bulbs in the stores,run regular bulbs in your house.
I started stock piling incandescent, and halogen par bulbs back in 2007 when I heard they would be banning them. I never liked cfl bulbs, LED are the same , but most have a sickening flicker.
Not only led's but led monitors also have this blue light hue. I do a lot work in the computer (animating) after a couple of years my eyes started to get way to tired and dry,that feeling when you come of salt water in the beach it actually stings a bit. So I bought the gunnar optiks,it has a lot of bullshit advertising like get faster reflexes n more headshots such n such. When you get pass that type of promo bull shit they actually say that it will block this blue hue and actually help with reading text n enhance a bit of contrast. I've been using them for about 6 years now I will not dare stare at a monitor without these lenses now, i could go on for hours staring at the monitor now n when im finished my eyes feel way better. You should give these a try, the help a lot n protect your eyes its just the way they present them kinda stupid.
There is a reason why my BenQ 2411z has a LowBluelight option.. which basically changes RGB scheme to lower blue levels thus everything is slightly yellowish. Weirdly though, first weeks when I used that feature my eyes hurt like bitch after 2-3 hours... now I am used to it and after 10 hours in front of monitor my eyes are nowhere near as fatigued as before. There is something to it...
You will notice it on white backgrounds.. like here on white BG that youtube has. If you ramp lowBlueLight up to maximum you will notice that white becomes slightly less blue-ish and becomes slightly yellow - nothing disturbing tho. However that is valid and useful only if you have RGB settings and white balance set properly (in monitor and your GPU drivers as well). Previously I had ASUS monitors and I must say that dialing that to perfection was easy.. but this benq... a lot of testing and eye fatigue had to be experienced before I mastered it :D
yeah on my laptop screen i use f.lux to change it to a orrange tit but im sure how much it really helps but i have noticed a difference and if i turn it off by screen is amazingly blue and i can bairly look at it anymore at off(also overtime ive been increasing the orange more and more as my eyes acustomise
Yeah true I just got some $10 PC glasses from the optometrist (sp?) and they honestly are already working (taking them off 2 hours later my monitor just looks overly blue lol).
I'm still using incandescent, and halogen bulbs. I pay little more for electricity, I dont mind. Never was fan of LED lightning. Also, still using CRT monitor. Never had good feeling from new televisions/monitors, they are probably LED backlit. Too bad, at least one company didnt let making new quality CRT monitors, Im sure still enough people have interest about them, so at least one company can live out of it. I'm finding banning normal bulbs as attack against freedom and rules of capitalism as people still wants them, and same as you can pay extra for luxury dinner, you should have option to pay luxury for electricity to have nicer lightning.
argh youll hate your eyes one you need trifocals...i first relized i neededglasses squirrel hunting looking in same spot then one moved he had been there couldnt see till he moved....sux is i was a welder for years andi bet that hurt eyes too even with best hood out there you get weld flashed by accident...sandy eyes feeling next day
Just to play devel's advocate... I'm not sure that the frequency would increase that much from red to blue in the Visible part of the light spectra. But I don't know

im hggunna test it mine are prescripts too from 2003 tho but the white on my phillips beillancemonitor is crazy bright meaning more blue cux coming from paint car trade the whitest whites had more blue in them...fords creamy white had yelloiw but thx for the ++
I wish all LED lights were obsolete. They ruin the night sky, they blind you when driving from oncoming cars and they even change the colour of items, so you're unsure of the correct colour (for people who rely on colour design). They are just awful.
Blue light doesn't damage your eyes, but looking at mostly blue light for a while before going to bed might degrade the quality of your sleep, and being tired in the morning will make your vision feel weaker. Warmer light sources like incandescent lights don't trick your brain into thinking it's daytime. Ultraviolet damages your retina, although LEDs are not large sources of UV.
Matheus Bitencourt I am changing the bulbs that I get exposed to for any duration at night to incandescent. Both led and cfl are great in the morning when you want to boost your serotonin production. Otherwise if you use them in the evening or at night you are interfering with your circadian rhythm.
Bret Fuzz you're damn right. I did exactly the same thing. I duplicate every light spot in my home, so I have a spot with powerful CFL at morning/afternoons and low power incandescent bulbs at night. I don't like led anyway
i've been digging into this because

I left my computer on while I went out to eat dinner for two ours and I guess the queque has somehow brought me here. I have no idea what is happening in the video but your accent is making it alright.
I subbed.
my retinal specialists uses this super bright blue light machine to test my retina.. it actually hurts to look at it.
After 15-20 minutes after looking at Led backlit screen, phone or being in a room with led bulbs or lamps i get headaches, horrible eyestrain, dry eyes, double vision, motion sicknesss, weakness in the whole body, losing the ability to mentally focus, this only happens to me from led lightning can stare at my ccfl and crt all day without issues.
The energy star bulbs make cold light which wrecks havoc I suffer from major depression severe anxiety etc. I like incandescent three way bulbs. transparent bulbs and color bulbs. 25 watt transparent incandescent make more light than a curly cue flurecent 100 watt equivalent. I do notice I don't expiance road rage at night from halogen headlights. led headlights I have to stop in the road to let led headlights go by because I can't see the road. first generation technology's the inventors got things right the first time.
oh yeah thats right
there is the hype and the initial switch from incandecent to LED light bulbs to save energy etc,
but those light bulbs hurt my eyes with the pure "white", which thanks to this vid now we know is blue
i made it a point to find low lumens light bulbs, and that are the old style, not LEDs, they hurt my eyes
so monitors can't be much different if not more direct!
I'll keep using my CCFL monitor for years to come. You can negate the blue light issue of LEDs by changing the colour temperature but, maybe it's just not the same?
You are correct led causes too much strain whereas cfl is very soothing. Led is very intense on eyes.
@1:45 it gets pretty dramatic
lots of articles on the internet about blue light, and how its like government-anti-conspiracy-level type stuff
i just want a monitor that doesn't give me eye strain
by the way, i got some new led monitors and that night after using them, i had some bad dreams.
maybe it was the game i played, left for dead, but
maybe there are some psychological/ physiological effects going on with the blue light frequency too
Led lights especially but lots of other bright lights leave a mark too.
What about house lights ? Which is best: classic bulb vs halogen vs neon ?
I think the problem was that your blue LED light was using, well, blue LEDs. Blue LEDs emit only blue light, whereas white LEDs emit other colors as well. However, not all white LEDs are equal, in fact there can be massive differences in the spectrum of the light emitted. One should probably seek out LED lights that have a warm white color instead of a cool white as they should give out more green,yellow and red light and less blue. Also many LED lights have a flicker at 100-120Hz, some bulbs flicker a lot, many has a bit of flicker, and a few have no flicker. Some people may be sensitive to that.
On the topic of monitors having LED backlights, I think it is less of a problem than in general LED lighting. The LCD panel has red, green and blue subpixels, and thus two thirds of the screen area will have color filters that block blue light. Only the blue subpixels will let blue light through. I guess if one is spending a lot of time looking at a mostly white or blue screen, then it can still be a concern, but most monitors provide a way to set the intensity of the RGB channels separately, so one can always just lower the blue value in the OSD and get a nice reduction in blue light.
Oh and some LED backlit monitors flicker too depending on the brightness set, and it can cause eye fatiuge in some people.
Thank you for speaking to this!!! My eyes hate led monitors. Looking to buy an old CCFL now.
Wow! That good stuff to know, Man! A couple months ago I was up late on my laptop and I actually started seeing black spots/smudges! I was kinda spooked cause they would've go away EVEN IN THE DARK! The next day I woke up and they were gone from my eyesight! I haven't seen them for a while now, But i do have to be a bit more careful!
Floaters?
what about OLED,is it better than led?
now what do we use? candles?
I used to play games on my iPod a years ago and it was the first time I noticed my eye sight becoming worse. After playing a game for nearly 2 hours I started to look outside towards a fence and it was Very blurry. I thought I was going blind so I took a nap that brought my vision back. Ever since then I think my eye sight has becoming worse. I can only see a meter away and then things start to go blurry. I can't see the stars or moon clearly at night. Traffic lights cast a light shadow around them. It used to look sharp, and definite, but now it's like a halo around it. Sometimes I get some type of double vision after long hours.
Garrett we need to raise awareness to the manufacturers guys....this is some serious issue...please take any action to stop them from making leds....i left my job and sitting home unemployed since i worked on screens
i am using one now, and to be honest i cant wait to go back to led... my eyes are killing me with my ccfl :c BUT i do think in my opinion ccfl give more light... thats my opinion thou..
Should we all be using those blue filtering glasses then?
I am trying at the moment.
I turned my monitor brightness down and I use low power LEDs for my room light because I found they physically hurt my eyes after extended periods of exposure, so it wouldn't surprise me if there was some science behind it.
Does anyone else have the same symptoms like me from leds ??? After 15-20 minutes after looking at Led backlit screen, phone or being in a room with led bulbs or lamps i get headaches, horrible eyestrain, dry eyes, double vision, motion sicknesss, weakness in the whole body, losing the ability to mentally focus, this only happens to me from led lightning can stare at my ccfl and crt all day without issues.
Kuzma Gameplays N' Music yes buddy i am facing this same issue with all screens only with led...i tried using yellow tinted lenses it helps a bit but not completely....we need to raise the awareness for the same...these manufacturers just think of business and money not our health
Kuzma Gameplays N' Music yes buddy I am going through the same problem it's permanently damaged my eye nerves...is there any cure please help...
I’m late to finding out as my tv was fluorescent for many years. LED TVs wreak havoc on my brain and eyes. The new OLED TVS are even worse for me.
Would Gunnar Optiks help in this case?
yes. but any blue blocker glasses would help. ebay driving glasses do the same job. just get the amber tints.
Stone Built
Yeah doesn't have to be $50 gunnars, I am using $10 glasses atm and they are doing the trick.
Is red led lights safer than blue led lights?
Great, informative video. Will keep this in mind for in the future.
Great video! I too use f.lux to try and minimize the straining effect of my monitor (specially in the evenings). Could anyone inform me on what the intro song is? Thanks
Flourescent light is also bad for your eyes. It's been tested by health specialist and opticians it has a very detrimental effect on ppl suffering from glaucoma. So I am assuming it cannot be that good for healthy eyes neither.
LED's are in fact not that bad in terms of lightning they produce, when compared to all the other lightning alternatives to the incandescent bulbs LEDs come closest to their gamma curve and is the most natural from the lot.
The problem with LEDs and particular the ones used in the monitor displays is that in many cases the companies are using blue rather than pure white leds f.e., even some of the ones that are supposed to be white has that blue peak. Maybe more than some.
Gunnar optics aren't actually guaranteed to protect your eyes from the UV light, the visible blue one yeah, but unless they sport a 100% uv protection on them I wouldn't be that sure that they are keeping your eyes safer from the "blue led" light.
What is more of a bet to protect your eyes and minimize the risk is glasses made from stuff like trivex that have inherited 100% UV protection. Polycarbonate has it too. Decent sun glasses with 100% uv protection work as well.
Other than that you may be able to reduce eye strain, but if you are talking about lowering the risk of long term damage you need to use something that has 100% uv prot, bcs uv isn't in the visible spectrum, at least not in the human one. You could wear tinted shades or spectacles, but without the uv protection you might be just as unprotected as you were without them.
is this true for led backlit monitors?
Yes.
Tech YES City fuck
LuminaryChief56HD use flux
Adam Hasso oh so thats what it does?thank god ive been using it then ^^
LuminaryChief56HD yeah that's it basically.
I feel sorry for Office workers, no wonder you see videos of Office workers raging.
Great info .
thanks for sharing
Warm white color led s good for eyes?
I have tape on the LED's for my Monitor, PC hard drive and my modem because they were too bright and they annoyed me.
Blink blink blink blink.
Bryan, could you test the program named F.lux to see if it helps you with the "LED problem"? It may be helpfull.
Get a lower frequency LED. It's not the LED but the color of the light.
Also that's cyan, not white. White light is the combination of all visible wavelengths.
Cheapass white LEDs use a fluorescent phosphor to make yellow to balance out the blue. RGB LEDs are much better for white lights.
Use a red/orange LED instead. They exist.
Don't worry people, soon all screens are going to be OLED = Organic Light Emitting Diode. A lot of smart phones already are. en.wikipedia.org/wiki/OLED
Is it still very expensive though? My Cowon S9 has AMOLEDs and that is 4 years old now... Guess it is just too costly to put these in a computer monitor :(
Tech YES City On August 13, 2013, Samsung announced availability of a 55-inch curved OLED TV (model KN55S9C) in the US at a price point of $8999.99. Soon we will see affordable TV's and Monitors. Some manufacturing companies have recently, came up with cheaper ways of manufacturing them.
Once when the prices drop & burnout is reduced or removed then yes
3 years passed,but...
I remeber I read/heard somewhere that our eyes are more sensitive to blue light.
also LEDs direct light more than CCFL or incandescent light bulbs, maybe the strong light is what is causing you the black spots?
if you ARE going to be a human test subject, try looking a bit into what the causes the black spots.
don't take it the wrong way, but I really hope that you are wrong cause I really LOVE LED's!!! =D
Nice vid! I was thinking of buying a custom gaming pc! Is this good?
Is this a good build?
PC Case: 1 x NZXT Source S340 Mid-Tower Case - White

All of this for just about $1700 (Australian Dollars)
That is awesome! I have the same CPU, GPU, power supply and HDD and man, the performance is fucking awesome. Totally would recommend those part. You will be more than happy.
If your going to buy a H97 motherboard, better to buy a non K processor. Go for a Z97 if you choose to stick with the 4690K for overclocking purposes. But all in all, looks like its gonna be a killer build. Happy building!
Hey Josh, Paul is right... it's either 4690 + H97 Mobo or 4690K + Z97 Mobo. If you want to overclock, and I suggest you do, Gigabyte offer some decent Z boards at that $150 range you want to spend. The PSU isn't the best, non-japanese caps, below average ripple etc and 750w is crazy overkill for the system. Look for something with better quality at 600-650w. The case also has no room for the ASUS DRW, you need an external drive to install Windows from a DVD. Also, get Win 8.1, not 7, all the negativity about it at release just doesn't fly anymore.
au.pcpartpicker.com/p/mwvfRB
There ya go! $1623 (without external DVD drive). Z97 mobo, better psu, slightly faster RAM, the rest is pretty much the same except... drum roll... and still under $1700... with... a 256gb Crucial Mx100 SSD!
Thanks for the info. Keep it up.
Interesting topic, at night time i run a 5metre RGB LED Strip around my room to give it some light, it can get quite bright so i do lower the intensity, but for me personally ive never really noticed anything different after been exposed to the LEDs for a few hours, even the next morning. Light doesnt affect me as much as sound, could be something
Probably still young (and invincible? :P).
Tech YES City haha my grasshopper-ness is a good thing
phew! i have old lcd's tvs an laptop, i dont have any led lcd
thanks for info,
also when cars with led lights crossover me they really blind me off by night obviously , once it almost got me off the road
Very interesting i will have to look into it myself
Folks they are using blue led on all electronics reason,to throw you circadian rhythm,that's what tell your body when to go to sleep.
At night instead of feeling sleepy and going to bed you stay up watching tv,with that blue led shining in your eyes or on your laptop.
By science it's fact blue light is bad for your eyes,the cars with led lights,when they came out with the flashlight you couldn't look into them because of the intense glow so why they use them for headlights?
People think having bright headlights on their car help at night but it doesn't because they only can be so bright,when it rains most the light reflects off the wet road.
The halogen is a nice orange glow,it's natural,led is not,our eyes are meant for the sunlight and the moonlight.
One way to stop this ,is stop buying the led bulbs in the stores,run regular bulbs in your house.
I started stock piling incandescent, and halogen par bulbs back in 2007 when I heard they would be banning them.
I never liked cfl bulbs, LED are the same , but most have a sickening flicker.
I think you should try out new stuff like this it was pretty intresting :D
Not only led's but led monitors also have this blue light hue. I do a lot work in the computer (animating) after a couple of years my eyes started to get way to tired and dry,that feeling when you come of salt water in the beach it actually stings a bit. So I bought the gunnar optiks,it has a lot of bullshit advertising like get faster reflexes n more headshots such n such. When you get pass that type of promo bull shit they actually say that it will block this blue hue and actually help with reading text n enhance a bit of contrast. I've been using them for about 6 years now I will not dare stare at a monitor without these lenses now, i could go on for hours staring at the monitor now n when im finished my eyes feel way better. You should give these a try, the help a lot n protect your eyes its just the way they present them kinda stupid.
que tu compraste, espejuelos?
Roy J. ya como hace 6 años q los tengo.
cuales son?
Roy J. gunnar optiks
ok
Great video bud!
so leds monitor are the cause for eye problems
NO,stupidity
Whats the music in the intro?
Funny! the article had the headline in blue.
LED very very dangerous for future
Why
There is a reason why my BenQ 2411z has a LowBluelight option.. which basically changes RGB scheme to lower blue levels thus everything is slightly yellowish. Weirdly though, first weeks when I used that feature my eyes hurt like bitch after 2-3 hours... now I am used to it and after 10 hours in front of monitor my eyes are nowhere near as fatigued as before. There is something to it...
You will notice it on white backgrounds.. like here on white BG that youtube has. If you ramp lowBlueLight up to maximum you will notice that white becomes slightly less blue-ish and becomes slightly yellow - nothing disturbing tho. However that is valid and useful only if you have RGB settings and white balance set properly (in monitor and your GPU drivers as well). Previously I had ASUS monitors and I must say that dialing that to perfection was easy.. but this benq... a lot of testing and eye fatigue had to be experienced before I mastered it :D
I've also been getting black spots. Now I know the cause.
update on ratbans in the crew...night times a bad time
I didn't know you have done this. Haha :)
yeah on my laptop screen i use f.lux to change it to a orrange tit but im sure how much it really helps but i have noticed a difference and if i turn it off by screen is amazingly blue and i can bairly look at it anymore at off(also overtime ive been increasing the orange more and more as my eyes acustomise
Yeah true I just got some $10 PC glasses from the optometrist (sp?) and they honestly are already working (taking them off 2 hours later my monitor just looks overly blue lol).
good information and video, ......What the hell is on the table behind you????
I'm still using incandescent, and halogen bulbs. I pay little more for electricity, I dont mind. Never was fan of LED lightning. Also, still using CRT monitor. Never had good feeling from new televisions/monitors, they are probably LED backlit. Too bad, at least one company didnt let making new quality CRT monitors, Im sure still enough people have interest about them, so at least one company can live out of it. I'm finding banning normal bulbs as attack against freedom and rules of capitalism as people still wants them, and same as you can pay extra for luxury dinner, you should have option to pay luxury for electricity to have nicer lightning.
Really good c:
I want to see a yellow led lights on the market
argh youll hate your eyes one you need trifocals...i first relized i neededglasses squirrel hunting
looking in same spot then one moved he had been there couldnt see till he moved....sux is i was a welder for years andi bet that hurt eyes too even with best hood out there
you get weld flashed by accident...sandy eyes feeling next day
Yeah LED sucks, I hate it. It only hurts your eyes with it's strong and cold light.
Yo white light contains all of the colors in the visible light spectra
Just to play devel's advocate... I'm not sure that the frequency would increase that much from red to blue in the Visible part of the light spectra. But I don't know
levy G.
Blue is 606-668 THz vs Red at 400-484 THz, quite a huge difference there :).
After 15-20 minutes after looking at Led backlit screen, phone or being in a room with led bulbs or lamps i get headaches, horrible eyestrain, dry eyes, double vision, motion sicknesss, weakness in the whole body, losing the ability to mentally focus, this only happens to me from led lightning can stare at my ccfl and crt all day without issues. I'm Fuckin' Serious about this.
ill guess ill be wearing myraybans2 4//7 lol
im hggunna test it mine are prescripts too from 2003 tho but the white on my phillips beillancemonitor is crazy bright meaning more blue cux coming from paint car trade the whitest whites had more blue in them...fords creamy white had yelloiw but thx for the ++
lol just looked atits boxx ...lcd
Am I the only one who searched for this cause I just installed led strip lights in my room like tiktokers :/
I wish all LED lights were obsolete. They ruin the night sky, they blind you when driving from oncoming cars and they even change the colour of items, so you're unsure of the correct colour (for people who rely on colour design). They are just awful.
I fell the same
Blue light doesn't damage your eyes, but looking at mostly blue light for a while before going to bed might degrade the quality of your sleep, and being tired in the morning will make your vision feel weaker.
Warmer light sources like incandescent lights don't trick your brain into thinking it's daytime.
Ultraviolet damages your retina, although LEDs are not large sources of UV.
incandescente ftw.
led sucks
Matheus Bitencourt I am changing the bulbs that I get exposed to for any duration at night to incandescent. Both led and cfl are great in the morning when you want to boost your serotonin production. Otherwise if you use them in the evening or at night you are interfering with your circadian rhythm.
Bret Fuzz you're damn right. I did exactly the same thing. I duplicate every light spot in my home, so I have a spot with powerful CFL at morning/afternoons and low power incandescent bulbs at night. I don't like led anyway
