I’ve found I have an intense psychosomatic reaction to certain bands of deep blue light. It feels like a combination of tingling heat, adrenaline, and gentle compression on either side, as if someone has reached right in and is massaging my adrenal glands. Most search results for ‘blue light’ are negative, but this is pleasant, not like anxiety. I love playing speed chess online with my blue lamp going.
It feels almost like a form of ASMR but with adrenaline instead of sleep. Anyone else experienced sth like this?
It happens with a specific lamp I got from Amazon that I think probably spills UV. A few things such as pre-existing energy levels or eating enough food also influence it. I have some more extensive logs and notes if anyone wants them.
I don’t mean actual blacklight, this is a mostly-normal blue lamp that appears to be spilling some UV. I don’t know if it’s actual UV. All I know is that anything yellow pings brilliantly fluorescent when I turn it on.
Not UV, but infrared, and no weird psychological side products…
The visible light spectrum is ~370-750nm iirc. I work with a lot of fiber lines and security cameras.
I’ve gotten “struck” by a stray beam of multimode fiber a couple of times in the eye. Saw the beam. First time I thought I was insane because I saw the deepest “red” (it wasn’t really red) I’ve ever seen in that moment. My headache following the incident proved otherwise.
Second time around it was the same. Deep red, headache, okay… That wasn’t a fluke. I go and check the NICs in the switch and sure enough they’re 850nm.
Start walking around after this second incident. It’s dark because most people had the day off. Looking at the security cameras it clicks for me that I can very clearly see every LED surrounding the camera lenses are red. Deep red again. Nothing new, never thought about it. They are indoor infrared nighttime cameras.
Also to note: My eyes are messed up like bad. I pay big money to have the super thin glasses lenses, and they are still twice as thick as the frames. I know the lenses in my eyes are bent pretty bad. I can see the camera lights with or without my glasses.
I mean the raging headache was more likely from the power of the laser, not the light. The lasers in the NICs are pretty dang strong all things considered, and I don’t get random headaches from the cameras.
I mean its kinda neat but nothing crazy. Its just if you lit up a series of 5 RGB LEDs, on the left you have yellow (R:255 G:255 B:0), on the right you have straight up red (R:255, G/B:0) with a gradient between. Now put a 6th LED to the right of the 5th and toss your best guess at the color. I wouldn’t call it red, but it’s red in the same way that turquoise is still usually called blue.
You can test your luck by staring into a MM fiber line and see if you can see it, but keep in mind there are warnings on these things for a reason. It will damage your eye if you look at it for very long, and if you can’t see it then you literally can’t tell that you’re staring into it until the headaches kick in.
If you ever have a utility reason to need to know if there is an infrared light somewhere, simply pull up your phone camera and look at the suspect item through your screen.
I definitely can… but it’s because those IR LEDs are high power LEDs unlike the IR LEDs in your remote control… high power / high output LEDs draw a lot of current and generate heat in the process. While the peak output wavelength of those LEDs is in the non-visible spectrum, the output curve is quite broad and it spills into the visible spectrum.
I notice a red dot sometimes but absolutely nothing like what Not described. He said he saw such an extreme shade of red that it spilled over into being essentially a new color. I have never experienced that and I think I would notice if I suddenly saw a hyper-red color that was far beyond normal red.
I wish there was a good way to test what range is visible to each person…
Like have a row of specially-tuned lights maybe 5nm apart in color. See what the highest number you can still make out is given a standard brightness between them.
