I've answered you in the first reply to this post. Please re-read it.Can anyone please explain why I'm able to see the blue colors of images at my computer monitor when the Eagle Pair goggles shall block light of 190-540 nm at OD 5 and the blue light is within the 450-495 nm?
There are more blue light in the "white" LEDs than in the "white" light of the sun.
Bill Nye is disappointed in you, as are the rest of us.
No. You are categorically wrong here. LEDs can be designed to have virtually any color temperature. In fact, most of them solt as retrofits in department stores are "warm white", which is LESS blue than the sun. Prove it to yourself. Turn on a typical LED retrofit in full sun and you will see it appears yellowish because of the decrease in relative blue emission.
This is even more ridiculous of a claim when you yourself admit you have some degree of control over the color temperature of your display.
This is even more ridiculous of a claim when you consider the sheer magnitude differences between the two. We're talking like 100 lux versus 200,000 lux for a monitor and sun respectively. Even if the sun had 10 times less blue proportionally, it would still have 200 times the blue intensity, simply because the sun is SO much brighter.
A cursory googling would disprove this nonsense https://en.wikipedia.org/wiki/Color_temperature
If you're claiming you're only sensitive to blue light if there is a reduction in other colors, you should immediately discard all blue objects from your house, since they reduce other colors while preserving the naturally occurring blue light. Wait, that sounds stupid. All your guests are going to think you're crazy. Better come up with another ad-hoc rationalization of how your blue drapes are lovely, while your blue desktop icons are deadly.
No. again you are categorically wrong here. The amount of flicker is ENTIRELY dependent on the drive method and has nothing to do with the light emitter itself. Half wave rectification (in the dirt-cheap chinese christmas lights for instance) flickers. Capacitive droppers flicker. The constant-current driver used in any modern monitor does not flicker. The current is constant, ergo the light output is constant.The LEDs do also flicker though is is said that the flickering of modern LEDs isn't detectable by the human eye.
As to your bigger problem here, Yes, there is a nugget of truth to bright lights (especially bright bluish lights) having the ability of affecting sleep patterns in some sensitive individuals. But there is no scientific reason that reducing it wouldn't be sufficient to overcome this. If taking the basic steps the doctor suggested aren't working for you, there's something else that is the dominating factor.
Wanna know what I think? Too bad because I'm telling you anyway. You are experiencing the nocebo effect. Now, this doesn't mean you're faking it. It just means the problem is psychological - but the problem is very real from your perspective. "Your brain makes it real," as Morpheus would say. You're convinced (for tenuous reasons) that blue light is harmful, so you see any blue light and immediately feel harmed, whether you actually are or not.
Troll or not, there ARE people out there that believe this stuff. And when they come to LPF at least, I want them to see at least ONE person pointing out how foolish their ideas are.Cyp., stop feeding the trolls
