Welcome to LED Strain!

ensete Make incandescent bulbs great again

Is this going to turn into a political rant about the USA?

JTL No political rant. The BULB act was submitted by a Republican senator but defeated under the Democratically controlled congress at the time. Now that Republicans control the Congress I think it has a much better chance of passing.

This isn't a call to ban LED or CFL lights (although nothing would make me happier to see that), it's simply acknowledging that a portion of the population suffers from a sensitivity to eco-lighting, and those individuals should have the ability to purchase lighting for their homes that does not cause them pain.

ensete Fair point. I was making a joke.

Similar restrictions in Europe (all EU states). They banned the production of incandescent bulbs, which is crazy knowing how much trouble the alternatives can cause.

KM I heard they got around that by selling them as "heating globes" now?

Forgot to mention that I live in the US of A. I see lots of incandescent bulbs being sold on Amazon and still see them in stores. The community that I live in replaced the LEDs near my condo with CFLs. Amazingly, it has made a huge difference for me as long as I still wear eyeglasses that filter out blue light. Apparently, there is far less blue light radiation emanating from CFLs than LEDs and at least one medical study appearing on the NIH website obliquely confirms this.

I am doing OK with my desktop computer. I have a 24 inch monitor that is non-reflective and use f.lux software. Along with this I wear Rx computer eyeglasses that are tinted amber and filters out a significant amount of blue light. As such, I suspect I have a somewhat different issue than most of the people who are sharing on this forum.

For those who may not be aware, the next generation of light bulbs may indeed be incandescent. Scientists at MIT developed an incandescent bulb that has the potential to be three times more efficient than LEDS, reported over a year ago. I sure hope that these bulbs make an appearance on the market sooner than later.

Chasanne But how many MIT innovations have actually come to market?

JTL While I don't have first-hand knowledge, I know a fair amount of people who are not sensitive to blue light who nevertheless have a disdain for LEDs. If the new bulbs are in fact more energy efficient than LEDs, then I think we will be seeing these new bulbs on the market someday. And I know of an optometrist who advises his patients to not allow LEDs in their homes. My only concern about the new bulbs is how long will they last before burning out, given LEDs known longevity.

Chasanne If they lasted even just a year I'd be all for them.

JTL You can buy multi year incandescent now. Not many people are away of them, but "rough service" and 130v incandescents are legally available for sale, and have lifespans up to 20,000 hours (Thats almost 7 years at 8 ours a day of usage). I have some in my home now as I am testing them out for my photophobia

You need to go a little higher wattage as the light output is lower. I am currently testing these

You can browse other models there too. I would not count on anything in an MIT research lab coming to the market. The best thing you can do is call up your congressmen and ask them to support a reintroduction of the BULB act.

alec Glad to have you hear, the more eyes on this (no pun intended) the better chances of finding the true root cause and a cure.

Be aware though that the monitor is only one part of this. A lot of folks asume the monitor is the cause of the issue since that is what we are looking at, but in reality the cause of the problem can exist anywhere in th entire display subsystem. You have video display hardware, drivers for that, cables connecting that to monitors, OS brightness, contrast, and color settings, and the monitor. An of them could be causing the issue and it can be different things for different people

Ananiujitha I had some trouble with this site because this text-box starts very small, and at the bottom of the window, so trying to type a full post meant a lot of scrolling in a little window, and a lot of sheer between the scrolling and non-scrolling elements.

Try writing your post in a text editor and paste it in the textbox when your done. Bonus points if your text editor supports Markdown for formatting.

Hello,
I would like to introduce myself to the community. I am based in Europe and I bought a 2017 5K 27” iMac some time ago. After a few months of light usage, last week I attempted to spend an entire day using it and for the first time I had my eyes completely dry and strained, headache and a feeling of warmth caused by the computer. Very unpleasant feeling, like motion sickness. Using night mode, minimum brightness, bigger font and low level of natural light in the room things are better because I do not have motion sickness anymore, but still the screen doesn’t feel right and I feel “confused” shall we say every time after using it. I decided to reduce usage of the iMac to the bare minimum. I researched this thing a bit and I stumbled upon the mega-thread in the Apple forum, which then led me here. I’m glad this forum exists!
I’m going to provide some background considerations on my health in the dedicated thread, and then I’m going to open two threads with my personal observations using computers and using TVs. Hoping that all of that can be useful to someone.
In the meantime some general considerations I had since that terrible experience with the iMac: first off, it’s reassuring not to be alone in the process of making sense of all of this and getting some attention from the manufacturers (by the way I am no expert and until last week I didn’t know anything of all of this); then, it’s sad to take note of how little is known about the issues we are experiencing in the broader medical community and (at least publicly) within the manufacturers; finally, I am now somewhat scared of this push for constant and fast progress in IT, discontinuing at the time previous technologies that were working perfectly, because this has led to problems for users that were perfectly fine before (let’s say whatever is causing problems was below the threshold) and these problems do not appear to be taken seriously by the manufacturers.

Harrison Sure, I'm Italian.

1. Do you use any smartphones that do not cause you strain?
2. Have you ever used Windows laptops/computer and have they caused you issues?
3. Have you ever had a comprehensive vision exam done where they checked for convergence issues and eye teaming? This is not done in a typical annual eye examination where they will declare you have 20/20 vision or give you glasses/contacts.
4. Any medical history you're willing to share?
