Um... I was thinking more along the lines of bluish lava lamp, not police strobe light in your face...

:lol:

blue and blueish light in itself is harmful … not limited to police strobes!

a lavalamp has a full spectrum incandescent light underneath … the blue color is filtered inside the oily substances… the lamp is not really emitting an excess of blue light… it is merely emitting the blue part of the spectrum present.

even the blue police strobes based on normal full spectrum halogen or incandescent lamps (RA > 95) are not per sé exceeding hazardous limits…

but the stronger the blue(ish) light, the greater the chance it becomes harmful to the retina, since the retina is especially very vulnerable to blue(ish) light.

blue and white LEDs are always emitting a dangerous amount of blue(ish) light, because they spike extremely in that part of the spectrum.

the white LED headlights (e.g. as seen in audi) are harmful to the retina…

the blue LED indicators in electronic equipment (e.g. hard disks, routers, TVs etc) are harmful to the retina…


blue light is seriously harmful for the retina…

ALL light is harmful to the retina, not just blue light. Blue light is no more dangerous than any other wavelength. Given sufficient intensity, any wavelength of visible light can literally burn out your eyes. Even ultraviolet and infrared light can pop your eyeballs like an egg in a microwave oven if the source is powerful enough. Our Sun is yellow, yet staring at the Sun can cause permanent blindness.

Saying that only blue light is dangerous is an outright lie.

Well that's just ambient light and wont change any autism at all. It's a load of potholed malarkey. You should take this belief to whoever told you about it and either politely disagree or say they're full of ass. Depends on who they are.

no lie. and not saying that only blue light is harmful.

blue light just has an extra twist… hence the term blue light hazard

Absorption of blue light, however, has been shown to cause a reversal of the process where cells become unbleached and responsive again to light before it is ready. This greatly increases the potential for oxidative damage.

Why not post the entire article ("High-Energy Visible Light"), instead of just the parts you want known? The italicised part is your quote, and the bold part is what is more significant.

Wikipedia wrote:
In ophthalmology, high-energy visible light (HEV light) is high-frequency light in the violet/blue band from 380 to 500 nm in the visible spectrum. HEV light has been implicated as a cause of age-related macular degeneration.

Some sunglasses are now designed specifically to block HEV.

Blue-light hazard

Blue-light hazard is defined as the potential for a photochemical induced retinal injury resulting from radiation exposure at wavelengths primarily between 400 nm and 500 nm. This has not been shown to occur in humans, only inconclusively in some rodent and primate studies (also a lack of authoritative references, and quantifying the conditions used) The mechanisms for photochemical induced retinal injury are caused by the absorption of light by photoreceptors in the eye. Under normal conditions when light hits a photoreceptor, the cell bleaches and becomes useless until it has recovered through a metabolic process called the visual cycle. Absorption of blue light, however, has been shown to cause a reversal of the process where cells become unbleached and responsive again to light before it is ready. This greatly increases the potential for oxidative damage. By this mechanism, some biological tissues such as skin, the lens of the eye, and in particular the retina may show irreversible changes induced by prolonged exposure to moderate levels of UV radiation and short-wavelength light.

So why the scaremongering? Why do you seem to be trying to stir up trouble where no trouble exists? Are you trying to generate a new conspiracy theory?

Now now fnord, that may be a good sentence to push against someone who seems to know what he is doing. But I don't think the OP seems in control, if you know what I mean. He's just a raft of a conspiracy, if he was a part of one.

I was posting against Aspie-Rant's post, and not the OP's.

does it occur to you why it hasn’t been shown in humans… and only in some rodents?

science tends to use rodents and other animals for testing… since it may ethically be problematic to use a human for such a test…

among other animals tested to determine the blue-light-hazard, bovines, baboons and rhesus monkeys were used….

according to this study at least:

http://www.naasln.org/documents/article ... _light.pdf

scaremongering? nah. easy does it….

a. There is a distinct absence of evidence that blue light is harmful to humans.

b. Absence of evidence, while not evidence of absence, is sufficient cause for reasonable doubt.

: : There exists sufficient cause for reasonable doubt that blue light is harmful to humans.

Did I ever mention that I came up with my own homemade cure for Aspergers? Its the techstepgenr8tion Metamucil method; it turns out that we don't process plant fiber the way most people do and that supplemental fiber indirectly reinforces the integrity of our small intestines, thus decreasing opioid flow across the blood/intestine barrier, thus directly impacting the mass degree of interruption we have of catecholamine transmission and reuptake!

Is it too late to say that I've got a bridge for sale in New York?
