I don't suffer from any light / lighting sources, thankfully. But now that many lights including street lighting is starting to use LED, I hope it doesnt cause me eye strain. Some highways I used have already switched to LED lights, but so far no eye strain from me.
Causes of eye strain, how to detect and "solve" them.

ensete Here are some DC driven LEDs I use:

(not flicker free unfortunately, but I don't use them for long periods of time)

(this one is one of the best flicker-free light sources you can get)

It seems that regular people can detect flicker at about 3000Hz and sensitive people up to 5000Hz.
Also incandescents could make a comeback:

PuffyCloud How many MIT "innovations" have come to market?

JTL LOL
You can still buy incandescents yourself. Only a very narrow slice of bulbs got phased out. 130V incandescents all meet the energy efficiency. There are also 120v 602 watt bulbs, same exact ones that used to be sold in store, in slightly smaller chandelier bulbs that are sold at Target and the like. Lowes and Home Depot doesnt sell them cause they get a much higher profit margin hawking harmful LED ligfhtbulbs, and they care more about $$ than people health and well being
You can search various online outlets and find incandescents for sale easily

https://www.amazon.ca/s/ref=nb_sb_noss_2?url=search-alias%3Daps&field-keywords=halogen+par30&rh=i%3Aaps%2Ck%3Ahalogen+par30 (my celing lights are PAR30)
Probably can't ship to US though
ensete Bought the new versions recently:

They changed the adapter and now these JANSJร lamps are no longer flicker free. I think they changed to IC LED drivers and now are very sensitive to the input electricity.
If you can still find the old ones you should be fine but these new ones will give you a headache.
PuffyCloud I have one that looks exactly like that. It's flicker free, guess it's the older model.
Most of my light bulb are incandescent or halogen. You can still buy them in Canada, but it's expensive.
I live in Canada and we still have incandescent lights. I have a tote full of them I probably have over 250 and a lot of them are the ones that last 7500 hours a bulb. I plan to fill up 5 totes enough till I die hopefully. I can't tolerate LED or CFL no matter what. I call my house the sanctuary with black out curtains so the street light LEDS can't get into my house. I have 4 plasma TV's and all Incandescent bulbs.
jasonpicard Should come and visit sometime
jasonpicard I'm also from Canada, lol.
Couldn't you also use halogen? I use 60w Halogen bulbs from Home Depot in my house.

MagnuM halogen is good. One advantage is it burns at a higher temperate so there is more red light. But when the sun goes down incandescent is better because it burns at 2900k which doesn't mess your circadian biology up as much. I have halogens in my bathroom only because of the light fixture.
jasonpicard Are you aware of any diseases/disorders surrounding sensitivity to circadian rhythm consistency or blue light's function in those cycles?
MagnuM the problem is when it comes to our issues I can't figure it out. I spent alot of times in Jack Kruse's forum and other Facebook groups and when it comes to this issue it's just a crazy mystery. For me one day in 2008 I couldn't tolerate ccfl flicker and LED flicker. I wish I could go back and use a CRT monitor. I tried with no success. I even bumped up the refresh rate and it didn't even matter.
jasonpicard What are your symptoms again, and how quickly do they come on?
MagnuM I used to think PWM was the worst that was until my work changed to 6500 K LED lights. Extreme blue light is the worst pain on the planet I think PWM I lived with for years because of useless fluorescent lights. With this BenQ GW2270 no orange glasses immediate. When I walk onto my shop floor immediate pain. I need to have the orange glasses on. I even have black electrical tape on the sides of the so blue light doesn't slip in the sides. This monitor and my work lights are flicker free. If I go to peoples houses it all depends but the cfl's swirly bulbs make me feel burning, dizzy can't concentrate, migraine, eye pain. I'm quick to recover now and it's been a long time since I have been really knocked out from lights. This past Christmas I went to someone's house with LED christmas lights. Even with the orange glasses after an hour the flicker got to me felt pretty terrible. I am not a fan of rush hour traffic because of flickering car head lights. I usually don't go outside after dark but I have no issues going to Tim Hortons when it's dark. We now use flicker free LED street lights at 3200K. I don't find them that bad. I was scared when they first changed over. I do have black out curtains in my house so those lights don't get in. I would say my problem is bad enough that I wouldn't put myself in the position of a full time computer job. Lucky for me I only use a computer for an hour or less at work. It's a different BenQ model and with my glasses it doesn't bother me. I bought that Samsung quantum dot monitor but am not a fan because it's 6500 K LED. I bought it because of the higher spike in red light but it didn't seem to help. This is the first computer monitor( BenQ2270) I have owned or used in about a year. I got sick of using a computer and was going to give up on phones as well because I was doing terrible. I spent almost everyday outside reading or other activiites. I'm pretty i'm the most sun tanned person in Canada right now
Right now though for about a year I have been fine as long as I guard against crazy flicker area's or extreme blue light. When I finish work I can look at good screens all night long if I want.
