your health
I have read every single post in this discussion and I took note of what I could be tested for (especially the convergence insufficiency). This is my situation. I have some hypermetropia (+0.5 +0.5) and I am slightly astigmatic on the left eye. Grey eyes. I have some issues if there is too much sunlight: at work I have problems (eye fatigue leading to blurry vision, but no headache and no nausea) if use a computer next to the window with the monitor perpendicular to it, but as soon as I move away things are back to normal. I could never ever use a monitor which is just in front of the window because the light coming from outside around the monitor would cause me problems. Funny how all my colleagues are eager to stay as close as possible to the windows and for me is the exact opposite haha. Last summer I spent a sunny day outside sightseeing with hat and black sunglasses lenses 2N, at some point I started to feel my left eye very fatigued and then I developed some blurry vision and I was forced to look down for a while every now and then for the rest of the day in order to get by. This has happened some other times and in all cases it was not a problem of looking towards the sun at sunrise or sunset, there was just too much light. I bought some new sunglasses lenses 3P and this summer things were much better, but one day I still had a mild version of that feeling in the left eye…Web pages with white background are not my favourite shall we say. When I used to work with Matlab I had a very relaxing colour scheme set up with grey background, and every time I had to switch to Outlook (white background) it was a pain, my immediate reaction was to look away.
At the moment I am also inflamed (high VES) but I don’t know it that means anything in terms of the problems I have with the iMac. I suffer from vertigo and if in the car I sit in the passenger seat I cannot look back to talk to people on the back seats because otherwise I have headache, and on the bus I cannot sit sideway because otherwise it’s headache again (I can sit looking to the front or to the back only).
If we go back 25 years, at the primary school I had issues with the neon light in the room and my eyes used to become red. I could see some circles of colour, in different sizes and different colours every time. That may have been more at night, but I don’t remember exactly. I was tested by multiple specialists, but no one had a name for that issue. It then stopped. Thinking about it, I had multiple tics in that period.
Also, my tonsils and adenoids had to be removed at the beginning of primary school; and when I close my teeth the upper and lower jaw are not aligned, it seems like the rest position is not what it should be, but I never had pain in the jaws.

Hey,
After doing my eye excercices for about 2 months now, my eye strain issue hasn't changed overall. However shortly after doing the convergence training screens are much more comfortable, but the effect doesn't remain.
Moreover it is possible that I'm suffering from an autoimmune disease named Hashimoto's thyroiditis. However it is not clear if this is true and I can't tell you much more than wikipedia about it.
I'm just dropping this buzzword, because somebody of you where already talking about autoimmune diseases.

Harrison Actually I forgot to mention a pretty important thing...almost at the same time I received the iMac, I got an inflammatory autoimmune disease. I don't know if there is a link to the iMac issues I have simply because both the computer and the disease arrived at the same time.
What is interesting though is that watching TV now seems to have become a demanding task, colours seems aggressive and unnatural, and I cannot focus very well when people move quickly on the screen. I've had this TV (VA panel, LED direct backlight, 4K) for a year now but I barely used it until recently so again the comparison with before the autoimmune disease is difficult...but I don't seem to remember having the feeling that watching this TV was a difficult task before...
Harrison However shortly after doing the convergence training screens are much more comfortable, but the effect doesn't remain.
Are you doing exercises with an optometrist or on your own? To me, this sounds like the exercises are working, but maybe you are not doing them as "precise" as an optometrist would have you do?
Could anyone let me know how checking convergence issues is performed by optometrist / ophthalmologist? Does it include relaxing the eyes somehow and observing how they look in their natural (not focused) position, or just checking whether eyes focus properly on different objects?

andc Write me the state or city where you live and Ill ask my optometrist to recommend someone reliable in that area.
Harrison Two months might not be enough by far. Ive been told I will be able to see results after 4 months tops. Its like working out or exercising - new muscle tissue and innervation is being built. I also do it under supervision (we share online excel with results and times and notes) and the optometrist adjusts the exercises by that progress. You really have to do exactly whats fixing YOUR issue, otherwise it wont work. But seeing that it helps already means you might be on a good path and it might be the reason for the trouble.
Also I wanna stress here again that I also train for accomodation, and that happens with an eye patch for one eye at a time only. So you cant rule out this issue by using eyepatch and seeing if you have eyestrain with it or not - the feeling from this exercise is different - burning in the eyes, more than strain.

andc You don't need a specialist to check if this is an issue. My recent normal optometrists visits all were able to confirm I had a slight vertical convergence issue (that I have known about my entire life) but in my case it's irrelevant as I have monovision anyway (one eye sees at a distance and one up close). I learned this when young and trying to wear glasses that corrected the close eye for distance as well and things were double and blurry. It's never been an issues for me and is not the cause of my eye strain as demonstrated by the fact I don't get strain on older devices AND correcting the vision and imbalance doesn't help the strain...so monovision is still working fine for me in all instances and irrelevant to the strain.
Point is if you got to a normal optometrist or two and ask to be checked for it they can easily do it with that standard machine they put in front of you when you read eye charts. No sense in going down this road if you have no convergence or accommodation issues at all as eye therapy is very expensive, takes a long time, and is of dubious benefit often. If you have a clear eye problem and want to try there is no health reason NOT to...but I know how desperation gets you to put hope in things and spend lots of money and the letdown can be huge. Since this is not a fast treatment I'd not waste my time and money if I had no documented issue. It's not some hidden problem...you either have it or you don't and prism glasses (that any optometrist can do fine) can tell you right away if it's your eye strain issue.

andc Its easier in and around Europe as they are more connected with my specialist.
JTL Ill ask about that area.
ryans Also.
hpst The treatment cost me close to nothing so far, but the prices probably vary from country to country. So far including the glasses its been about 367 dollars, most of it being the glasses price. It wont cost me more than another 90 dollars before the training is finished. But I have been lucky to find a guy who is also young, interested in this issue and research around it and what new understanding it may bring into his field.
Theres of course no point to waste money in traning if the glasses they can make do not improve the situation - so thats a good first step. For me they improved it from migraines to discomfort from longer use, meaning there is some connection. And to stress it - they are not all around solution, their features are strengthened to the point that I cannot see farther than 1m with them sharply, it was crafted purely to test the issue. The guy I see about this is a specialist and he told me only about another 2-10 ppl in this country take the field seriously enough to figure this out. So I think who you run into matters a lot.
If that doesnt work, or help only partially, then it is -
1. waiting for results for Lyme disease (had to pay for that too, cost me as much as the whole eye training)
2. getting more precise oscilloscope to measure all I can
3. trying to get my hands on a sprectrometer to measure light spectrum on all devices and bulbs to see whats up
4. getting possible new drugs for migraine
5. getting all neck muscles balanced and fixed (scm, scaleni, all the classical migraine trigger points)
6. getting media attention through lightaware.org that this issue is serious
7. Hoping someone makes a color e ink
8. Moving to a tropical island and teaching surfing, or joining an amazon tribe, never to see displays again
Id also like to figure out if I can get an iphone thats troublesome, remove its backlight someohow and still make it run, so I can test if it could be only the backlight.

martin Thanks! I see it's possible to have Lyme for a long time and not get treated https://www.today.com/health/ticked-10-years-living-lyme-disease-2D80555054

https://www.amazon.com/Better-Solving-Mystery-Chronic-Disease/dp/1250019400I made a short survey about Daily Life/Health/Led Strain Problems. Maybe it will allow to find some common patterns in daily life of people with led strain problems. That could work as additional triggers for led issues.

That's right - Lyme is a very sneaky disease. It can cause almost any type of issue, is hard to be diagnosed (there seems to be no 100% sure way of testing it) and can even hide for many years within one's body, so you may think you're cured and it will get back after several years.
On top of that it's cured by a long antibiotics therapy (1 month or longer), which may end up in other issues if you don't follow the diet, or don't use probiotics. If it wasn't enough during this therapy you may start to feel much worse due to Herx effect. I don't recommend it to anyone 
WOW! I just had one of these occur. My second one this year:
https://en.wikipedia.org/wiki/Scintillating_scotoma
https://en.wikipedia.org/wiki/File:Scintillating_zigzag_scotoma.gif
During my lunch break at work today, I went pretty hard on a flight of 200 stairs with a pretty steep incline, 5 sets, and it was also a pretty nice and sunny day. I'm not sure whether I overexerted myself, or if it was the bright sun.
The other time this happened this year was in the spring when the NHL playoffs were on, lol. I drove to my parents house to watch a game and there was a low sun as it was spring at the time. While watching the game on my dad's OLED TV (The same one as I presented here: https://ledstrain.org/d/175-oled-tv-same-issues/91), one of these started to happen halfway in. However, the sun was setting at the time and as very bright over the horizon out of my peripheral vision. I thought the OLED TV had done it, since the jury was still kind of out on it, but I didn't have any LED exposure today. Also, I am usually able to watch a 3 hour sporting event without much difficulty on the OLED TV.
What's strange about these phenomenon is I don't get any headache or ill-effects afterwards. The "attack" is pretty intense and lasts about 20-30 minutes, and then it spreads to the corners and ends. The "Signs and symptoms" describes the issue exactly. I had this very bright flashing squirmy wormy in my central vision after coming back from my Stairmeggon lunch break and grabbing my lunch bag out of the fridge. It was very intense at first, then started to spread to the corners, almost like spreading butter on bread. Once it had migrated more to the corners, my central vision was clear again, and I could read again, but then the peripheral was out. At it's worst point, I'm almost completely blind in one eye for a few minutes (left eye) until it spreads out of the way.
If I recall correctly, I've had these my whole life, even since a kid, but I just thought they were normal and that everyone got them. I must say, although a bit scary, they are one heck of a fascinating phenomenon! Just another oddity to throw into the enigma!
Interesting, that just proves that many of us indeed may be migraine sufferers with specific triggers. Which kinda sucks, as those triggers right now seem to be in all tech.
I got checked for Lyme disease, best test there is (westernblot) and interpretd by a friend doctor, its negative, I do not have Lyme, nor have I ever had it.
The theory on the website about visual center processing being attacked by some virus is still interesting to me. I will finish the visual therapy and see what happens after.
Harrison Yes, same here, 4 months to see any change, 6 to see possible cure just like with the glasses. Maybe more. I dont care, Ill do it as long as I have to if it helps.
