All fluorescent lamps utilize a mercury vapor arc inside the lamp. The ultraviolet light from this arc causes phosphor powders coated on the inside surface of the glass to emit blue, green and red light (the net effect being white light). The red emission from the phosphor has a slow time decay, and so the red light has a low amount of flicker (the red light is integrated over time). The blue emission is very fast and has the most flicker. This is why, in spite of good intentions, the expensive full-spectrum (more bluish) lamps have a greater subliminal flicker effect on the brain (unless their ballasts happen to be of the type that removes all flicker).

Since the worst flicker is in the blue, it is helpful to wear glasses that block some of the blue light. Therefore amber or rose-colored glasses, especially when worn together with a visor or a hat with a visor, allow us to be more comfortable under fluorescent lights (for rose colored dye for your optician, see http://www.callbpi.com/htm_cat/fl41info.htm). For some people, taking the supplements bilberry and/or carnosine before going into fluorescent-lit areas can reduce sensitivity to flicker.

    I know this is from 2012 article but we are still not there yet.

    Hopefully LED lighting will become less expensive to the point where they can replace compact fluorescents. Some of the newest LEDs just becoming available have a natural, warm and pleasant color. Theoretically LEDs can be flicker and EMF free, but unless the electronic engineers who design their power supplies develop a biological conscience, they will use switching-type supplies (which are high in EMF) and will operate the LEDs in pulsed DC mode (which will generate additional large amounts of EMF).

      Another good color lens alternative is irlens syndrome color filtered lenses. It can help artificial light / screen sensitivities.

      Btw would that be emf or ef as the trigger? Haven't read the links yet, my eyes are really tired. i do have a GQ emf-390 meter and acoustimeter rf meter. I was going to do some testing

          jordan Another good color lens alternative is irlens syndrome color filtered lenses.

          This was a game changer for me, haven't had the chance to get one that works for screens yet unfortunately, but custom calibrated irlens is what I have with my outdoors distance prescription. Depth perception is like 1000x, stuff looks like how it used to look before 2012. Also helps lessen the effect of whatever cheap LEDs/fluorescents are around when I'm out and about.

          More sense of direction (every time I put the glasses on I actually start walking slower for a sec, because the proportions of everything feels slightly bigger and distances feel wayyyyy more accurate and even), easier to find my way in crowds, generally makes days out actually rewarding instead of tiring.

          I see a bunch of stuff through them that I didn't even know existed right in front of me till I did a trial for the first time, of course I've already had normal glasses before this so it's much more than just extra clarity. Sooooooooo much better than Neurolens which didn't do much for me at all.

              If you have those devices you should measure all that you can, both rf and ef. Find out what is triggering high readings. Some "all-in-one" devices can measure RF, EF, and Magnetic Fields.

              https://ec.europa.eu/health/scientific_committees/opinions_layman/electromagnetic-fields2015/en/index.htm

              The term “electromagnetic field” (EMF) is frequently used as a generic term, however, it actually comprises quite different frequency ranges that differ considerably both with regard to physical and biological aspects. EMF comprise static magnetic (SMF) and static electric fields (SEF), extremely low frequency (ELF), 1Hz – 300Hz, and intermediate frequency (IF) electric (EF) and magnetic fields (MF), 300Hz – 100kHz, and radio frequency (RF) electromagnetic fields, 100kHz – 300GHz. Up to the RF range, electric and magnetic fields can be considered independently from each other, while in the RF range, they are tightly coupled together like the links of a chain.

                  jordan worked directly in a room with a specialist, very little lighting with just natural light barely coming in. Started with eyes closed then a bit later eyes open, swapped between like every possible of the several dozens of combinations, then did that all again a second time to create a double stacked filter. Every now and then would turn on incandescent lights and evaluate how it looked, that's when I got my first wow moment when the lampshade of the lamp that was turned on was like 100x more 3D than it usually would be for me.

                  Eventually went outside, I ended up looking down from a balcony at some fountain and my mind was blown, I almost thought I wanted to cry for a sec since I hadn't seen a fountain look like that since like 2008. (For reference, I am currently 21 years old btw, so that is a LONG time ago.) That's when I knew these color filters were the actual real deal and not just some theoretical idea lol.

                  I don't know exactly what color I have, I don't have the documentation with me right now. It has a bit of the orange effect that night shift modes on computers do, but is noticeably different from regular blue blocking glasses (which I had before) since some colors like teal and deep blues actually get more saturated. A bit of subtle greenish tint in there too maybe?

                  I remember that there was some more elaborate description of the color formula that was printed on the lenses before they were cut, but I was instructed to not take any pictures, I'm assuming the exact formula is patented etc.

                    photon78s I'll start testing more. The svd 32 rlcd I did test the EF as seen here https://imgur.com/a/Wz1EFjt
                    I haven't really tried the svd btw for eye comfort because I found out it's 6+2frc.. just don't wanna risk it right now. Did peak a few times at it is all.

                    I tried a tv in my house and it didn't react like the svd. I mainly got the Rf meters to check earbuds which ALL AIRPODS ARE BAD BAD. Sony xm5, OnePlus buds, status 3anc are much lower for example. The emf390 is a all in one but it's alot better than trifield one. The acoustimeter is more sensitive so it's good to scan rooms with.

                        I had an XM3 or 4 (don't remember) but I never used it in bluetooth mode, just wired headphone jack. I have not tried those low emf headphones that use an air tube. Where practical or convenient, I just use speakers or traditional wired headphones.

                            photon78s I'll test every monitor I end up trying tho. I kinda went off topic with headphones haha. But I have tried aircom air tubes and they aren't bad, was expecting worse.

                                jordan

                                Headphones paired with your phone are a huge source of potential risk (not to mention distraction, addiction, etc.). I find it really troubling that more and more "younger" folks are also having to do all of this.

                                  It's probably not a good idea to be using the Opple Light Master via bluetooth as well.

                                  The Safe and Sound Pro II RF Meter display flickers at regular camera visible frequencies. No need for me to upload video.

                                  https://safelivingtechnologies.com/products/safe-and-sound-pro-ii-rf-meter.html

                                  The flicker sensitive do not care about the emf sensitive and the emf aware are not concerned with their own product's display flicker.

                                    photon78s I have the GQ-EMF390 which is emf/rf/EF meter that uses a rlcd (I leave backlight disabled)

                                    Also the acoustimeter am10 RF meter I have as well. I don't think it flickers either

                                        jordan

                                        Now I see why you were asking about EMF or EF. Different products use the term "EMF" differently. For example, the trifield says AC magnetic field (units of milligauss).

                                        Hard to say in my personal experience if it is EMF, EF, RF, dirty electricity or all of the above as trigger. How do you feel about using these displays you are testing at a greater distance than normal away? As you know, the intensity drops off (attenuates) with distance.

                                            photon78s acoustimeter definitely has the best sensitivity as my router is downstairs, I have a Sonos one wifi speaker in my bedroom, it will pickup the rf between them. It's an awesome meter I found out the Rf is going through where my head would be on my bed.. I don't keep the speaker plugged in anymore after that. The GQ one also isn't too bad either, I did research before buying them. I think the trifield requires you to be right on the source to pick it up from what I heard.

                                            The acoustimeter am10 btw has an audio mode that I can hear the wifi router frequency, when the router is unplugged it goes away and you can hear other frequencies which helps to find the source device of whatever your picking up.

                                                jordan

                                                Great that you found these things. I do not use the trifield (model 100XE) for RF. I only use it for a rough idea of alternating current magnetic field and electric field levels. For RF, it is not able to catch the more modern types of pulsed high frequency signals.

                                                    photon78s gotcha. I think the trifield is ok for emf but RF I heard it's not good. I think both of my devices can go up to 8 or 10ghz supposedly

                                                        photon78s that's why I didn't consider buying those meters. Might have to make our own with a raspberry pi or something 🙄 wish they could just use a basic display.
