FL-41 filter Glasses
From which company ? I have them from Theraspecs. It does help me a bit sometime, especially the evening.
For the Irlen ones, which color ? Did you have the proper test with an Irlen Specialist ? What made you make a second pair of irlen glasses with different color ?
Have you tried Irlen Overlays on your computer screen ? Because I have problem only when reading on a computer screens (eyes strains, nausea, blur vision ...) but I can watch movies without problem. I had a pair of purple/rose/blue mix, tinted Irlen Glasses made, after I've got tested by an Irlen Specialist, and it didn't help me much when using it. But I've got a big improvment, when I put Irlen Overlay (purple and or rose) on my computer screen.

jasonpicard stay away they are garbage. They were meant for fluorescent lights. I own a pair. Pretty much did nothing. You feel like death if you wear them in a led environment.
I inquired at Theraspecs. Their answer was
The FL-41 tint is designed to filter the most harmful wavelengths of light for individuals with migraine and photophobia, shown by research to be at and around 480 nm. This is within the blue-green area of the light spectrum, which is very prevalent in LED and fluorescent lighting.
I have not yet tried their glasses (or AxonOptics's) though, because the importing costs a fortune, between shipping and taxes.
AGI I think what this Theraspecs company is doing is terrible. They know darn well their glasses were marketed for fluorescent lights as I think I bought my pair in 2011 - 2010 when LED at least in Canada was barely a thing. There was even some write up about how they blocked wave lengths that CFL's used. A cheap pair of SCT orange glasses off Amazon especially with some black electrical tape and a hat will do the trick of letting little light/flicker into your eyes and completely blocking blue light so much so that you don't even see blue light. It really is a trip the first time you wear them. This December I will have been wearing my SCT orange glasses for 3 years at work.
jasonpicard I have terrible pain at school now because of the lights. Just first day today! I have no other options in my life but have been given a second chance with this schooling.. How do you deal with wearing those glasses? Do you get looks? This is the number one thing affecting my future right now. Maybe I just need to suck it up.

degen Oh yeah you get looks. Usually most people are reasonable about it. I just tell them I have crazy issues with LED lights and I get can't tolerate them. Everybody is used to me wearing them now so nothing gets said. I get no migraines or eye pain if I wear them in flicker free led areas. I have to wear a hat though to stop the lighting from coming over head. Hopefully your school has flicker free lights. You will still get pain if not unless your not sensitive to flicker. Good luck! If the school uses CFL though SCT orange doesn't really help because there really isn't enough of a blue spike in those lights.
jasonpicard Does it still hurt if a small amount of the light indirectly enters your eyes from the sides while wearing the glasses?

KM No I do good with my setup. My work lights are flicker free ( I requested those to by talking to my boss) so unless I take my SCT glasses off I'm just fine. Ever since I figured this out I have had no issues with strength or stamina at home with good screens. I'm sure when I came up with the electrical tape on the sides so no light gets in at first people thought I was crazy. I had to explain it to a lot of people but all my bosses don't understand fully but they get it. I even had to explain to a group of 8 higher up guys why I wanted to request flicker free monitors in the shop. I even got thrown on the spot because my boss told me he had no problem doing it but he needed permission from the higher up guys so I got thrown in a meeting about it. Now we have all View Sonic gaming monitors down in the shop. I find that kind of funny because I was only asking for flicker free monitors. I didn't expect them to go all out. The monitors are less then 200 a piece though so they were going to buy all new monitors for everyone anyways. I find when you explain these things most people don't realize lights and screens are pretty much the same price if you are only talking about flicker so they have no issue with it. It's only when you get involved with those violet chip LED's do things start getting expensive. I saw another one of those violet LED's I believe the company was called Soraa or something like that. The lights are white but it's missing the blue part of the spectrum they were pricey though.
jasonpicard My work lights are flicker free
Are the lights in your working place fluorescent or LEDs?
AGI Flicker Free 6500K LED.

jasonpicard Thanks! So you are saying that Theraspecs or whatever blocks blue light do not help in case of flickering LEDs, but you do still use such glasses in a flicker free LED environment because at 6500 K there is plenty of blue. Hence your conclusion is that you are sensitive to both flicker and blue light. Is that a correct summary of your condition and findings?
The temperature of my light tubes in the office is 3000 K! I hate talking of feelings, but paradoxically I feel low temperature bothers me more. Maybe I should get a higher temperature bulb up on the ceiling and see how it goes. Yesterday I was in the office until night. It took me ages to write an email. I went home, took a break for dinner, sat under my fluorescent overhead light at home and I was much more performant. That light is clearly more blueish. How come if blue is evil?

AGI I use SCT orange. I know Theraspecs are a scam and I'm not a fan of them because I think they are scamming people because they used to market them as blocking wave lengths for CFL. I wore my Theraspecs to my work one day and after 1 minute thought I was going die. They don't block any blue light the way they are claiming. This is not really an issue with CFL because it barely has any blue light compared to LED. SCT orange with black electrical tape on the sides and a ball cap so I block light from all sides. When it comes to light bulbs yeah blue light and flicker are my main problems.

I'm not able to use LED bulbs and monitors without pain even when they're flicker-free (aka very low flicker, as they all do flicker a little) and I wear orange blue-light blocking glasses. I have checked the latter actually block blue by using a handheld spectrometer. I have no idea what's going on actually. This condition is truly disastrous. I have even tried frosted glass in front of the bulbs, while making sure no light could escape from the sides. It did not help at all. I compared online charts of different light spectrums. It seems natural daylight has pretty much all wavelengths at extremely high intensity yet it causes no pain at all. So unless for some obscure reasons the relative wavelength distribution is more important than the absolute intensity I'm not sure if any filter glasses could ever help in any way.
KM Keep in mind comparing LED lights to LED monitors is completely different . Monitors have at least 20 other different factors possibly more for creating eye strain/migraines.

Yeah, that is what I had thought too, and that is why I am considering the glasses. I do have orange UVEX goggles worth USD 10. They do not help, although I verified with a spectrometer they effectively cut blue and green. The optician says the low quality of those lenses may cause more downsides than benefits, but I have not yet fallen to purchase his Nikon lenses which are over USD 400 inclusive of frame.
I am really desperate and wondering whether it is worth to eventually waste other bucks rather than sit here and do nothing. That for sure is not leading anywhere. To be honest the main reason why I have not yet made the investment though is that the guy showed me a bunch of lens colors from bluish, purple to yellow, but was unable to tell me why one rather than the other. That proves to me that, no offense, he is not competent. "Some people find a certain color more comfortable" is not a satisfying scientific / technical explanation. I won't be allowed to swap lens color if it does not work.
AGI I believe some people probably just have issues with the way that LED emits it's light. It's not 360 degrees like an Incandescent. Look at a LED bulb package it tells you the degrees of light it emits. Most I saw were not 360. The stupid lights just shoot to the back of your brain.
jasonpicard issues with the way that LED emits it's light
That is another unexplored, potential source of troubles. However, I am actually re-thinking of something you mentioned months ago. The CRI. For some reasons I seem to be bothered more by low temperature lights. They feel very unnatural to me. I'd be curios to check what their CRI is.
@KM I am not sure you saw this post of mine. Do you think one could be sensitive to such a high frequency, assuming my measurement was carried out correctly?
