There are a number of problems related to blue light from LED monitors and televisions and many are now made the suppress the blue output and this is not noticeable to the viewer.

What I think is crazy is how many people talk for hours on a cell phone that is pressed against their head the entire time and subject it to the radiation being emitted. Spending $10 to talk hands free and with the phone away from the head is something that very few people do in the U.S. so it will be interesting to see the end results with brain cancers and then try to determine how much is from cell phones and how much of it is from other radiation sources like Fukushima and Roundup.

It is not the color blue but the wave length of the light. LED lights at 5000K and higher is what is suspected. The way the LED light enters the eye. Again there is a whole science behind LED lighting and many people are using the wrong lighting for different applications. Many people do not read up on the subject. They are too busy trying to make a living to pay bills. They now have office lighting that changes color or " self tunes" itself through out the day. It starts out at 2700K then goes to 4100K and back down to 2700K as the day progresses. It is suppose to simulate the sun and the light outside. If there is damage done to the eyes we will not see it for another 10 /15 years.
Give me the old 75 watt incandescent lamp.

Again, 5000°K LED light is similar to daylight on a clear sunny day at mid-morning or mid-afternoon, but without the ultraviolet. It is unlikely to be a vision hazard.

BTW, New research from Neitz Labs indicates that the alternation of blue and orange light may have much more effect on circadian rhythms than blue light alone, but this is very new, and still subject to verification.

We can't eat bacon, hotdogs, eggs, milk, pasta, red meat.... Salmonella, listeria, ecoli.... The fish has mercury or PCBs. Burning coal emits radon. Global warming. Global cooling. Don't breath the air. Don't drink the water. Don't swim in the water. Don't look at the LED lights. Asbestos, Lead, VOCs, Silica dust,.... It seems that being alive is hazardous to your health.

I remember about 25 years ago there was much ado about EMF waves from the power distribution wires and cancer. There was a local school that had a very high reading on a gauss meter and the PTA got involved. They had the power company raise the wires another 20 feet. It turned out that it was the electric heat for the classroom.

Yeaaah. There's a real issue with circadian rhythms that is still being worked out, but I simply cannot see how normal levels of blue light alone can be a serious vision risk.

It might be something to carry around in your bag of information when discussing colour temperature with customers, especially if you’re dealing with health freaks.
I just read this thread and sure you must be referring to Light Emitting Decorations.

What ever happen to that guy, did he just give up?

Loooooooooooooooooooong story short, this "blue light" garbage is just that,...garbage. its all bull****.



Dont believe any person selling eyeglasses etc. tsk tsk, i didnt hear about it until i watched a "marketplace" showcase ie indepth journalism on the topic.


just "search" , "cbc blue light"



i didnt even kno that was a 'thing' lmfao, i feel left out. its bull**** all the way anyways, there IS evidence however that blue light does affect your sleep cycle, but thats only if your a night owl etc.


if your 'normal', staring at a screen all day wont do a ****ing thing to you, your pc screen etc or tv doesnt have enough power to give off enough of the so-called blue light to do any harm.
