I think there's pretty much only truth to that. I had dry eye/eye strain from my first LED monitor which was a macbook back in 2010 only for 3 weeks but I was young back then. My dry eyes/eye strain officially became a chronic problem 7 months ago when the weather got cold and all of sudden we were getting rains everyday here in southern California. THere are different pollens for every season weather. On top of that, some family member of mine brought home huge amount of flower and kept it in the house for 5 days making the house smell unbearable. My eyestrain threshold has been so low ever since, to the point where I am turning my screen down to 0% brightness + plus another brightness slider to lower brightiness + influx basically turning down blue light as low as possible. THe newest thing I am trying now is lowering the contrast to 30% lower than the default, this seems to help a bit more as well.

So pretty much with the theory (if proven) in mind, the environmental supremacists/LED fanatics could legitimately claim that LED doesn't cause any problems and that we should have our auto-immune disorders fixed first.... am I correct?

anyways I am going to take a look at your subreddit post now. Thanks a bunch!

    I would not say thats the case. When people have a problem, you accommodate them. Light sensitivity is a disability like any other. If you were in a wheelchair, people shouldn't not build you a wheelchair ramp to save wood. It's not worth the effort.

    Also, it's not sure our thresholds CAN be raised. Given the absolutely minimal environmental benefits, and the well document legitimate health hazards LED lights present, there is simply no reason to use them. The price in human suffering is not worth it. They are simply unaware of the effects that we suffer from, so they are forming their opinion from a place of ignorance. It is our job to educate them so they realize the benefits of LED's are not worth the suffering and damage they cause

      I feel like the problem is that most people who have the same problem we do don't have as severe to the point where they have to turn the brightness level to below 0. I've talked to a few and some say "sure LED is too bright that's why I wear protective glasses and I'm fine now" they would stop right there and wouldn't give a damn or two about it beyond that.

      How rare/common is it to have the threshold so low to the point of suffering like we are? I came across a site and it claimed 1/4000 people but I don't have the link of it anymore.

        From my research, roughly 10% of people suffer from this level of photophobia.

        Yesterday I learned that while you can still, from a few sources, buy regular old incandescent bulbs in EU countries, their import is banned since February 2016. So they really sell the rest now and it's declining each day. And you can't import them anymore. Not even from China. I advise anyone who lives in an EU country to stockpile now before it's too late.

        I would've looked forward to nothing from Hillary. Even if this is the only policy Trump is good on, it is better than nothing.

        Please do write your congressmen, and the president stating your desire to see the EISA restrictions removed. Ask them to reconsider The BULB Act (H.R. 2417) which removes these restrictions. This is a rare chance to get this done given the current administration we have.

        KM After further investigation I found out that FfT bulbs are indeed flicker free. BUT these bulbs are very sensitive to the input electricity. If the input is not perfect these will flicker and will give you a headache like you mentioned.

        You should test that "Flicker free technically" bulb you bought with a UPS(disconnected from the mains to generate perfect input for the bulb, otherwise you will get the same input as the mains) or with a Voltage Regulator.

        Let me know this works.

          PuffyCloud I'd imagine using a pure sine wave double conversion UPS would help as well,, vs one that just filters the input electricity and switches to battery during an outage.

            JTL I was investigating a UPS a while back because we had very bad voltage fluctuations at our house and I wanted to protect sensitive electronics. All of the Cyperpower units and all of the cheaper APC units either a) no pure sine wave output or b) not fast enough response time (4-8 ms in Cyperpower units to switch to battery power, but pro APC units had very good 2ms response, which is enough)

            So if you want to regulate voltage through an APC you have to go for some of the more expensive and not entry level APC units.

              Apparently the UPS has 0 ms transfer time 😮

                degen Because it always runs on battery, just constantly charging when power is plugged in.

                Also works as an great surge protector because of that.

                Has anyone tested these bulbs?

                https://www.amazon.com/dp/B00MNU0BSQ

                Customer care claims: "Our Finally light bulbs do not flicker. We have found customers who are sensitive to flicker and blue light really enjoy our light bulbs.".

                  PuffyCloud It sounds like you measured the "FfT" bulbs you tried. Did you measure any frequencies, and what exactly do you mean by "they go dark"? Like, really no light anymore? This might be very important, please reply.

                  I just measured my headache bulb which I still own with my oscilloscope setup. It is the "GreenAndCo TM-A19-6W-E27-W". I did not find frequencies other than 50 Hz and 100 Hz apart from very small fluctuations around 60 kHz. The latter are so small they only truly appear in the spectrum analysis (and only in AC mode). And the visible 100 Hz ripple appears to be very minor, too. At most 5 mV out of 600 mV total amplitude. That is well below 1 % difference. Can such small differences really cause headaches?

                  These Chinese Corn LED bulbs do flicker (pencil test), but they do not cause any eye strain for me.

                  Their parameters:
                  Voltage: 220V
                  LED type: SMD 5050 (square).
                  Color: warm white.
                  Image:

                  The bulbs which DO CAUSE eye strain to me immediately:

                  Brand: Philips
                  Voltage: 220V
                  MPN: 9290011717A (9W, warm white)
                  MPN: 9290011718A (6W, warm white)
