My possible solution, treatment and progress so far

tfouto The link doesnt work.
I had another meeting with my optometrist. He told me that basically with my kind of deviation from normal vision, hes suprised the new displays is the only thing causing me trouble, as it should show in all areas of my life. I have 20 points deviation out of possible 12. He said I should maybe be thankful that I started having these issues, as otherwise it would go unnoticed and develop into a lot worse case of possible visible strabismus or diplopia in couple years.
I explained to him the idea behind dithering and he said it makes a lot of sense for it to be really disturbing, and that the therapy should hopefully fix it. Hes also willing to dive more into research when hes more free and said that it would be amazing if we found a specific proof of it (dithering etc), as it could make a good article. Also different polarization than in the past could be the cause.
He also mentioned a lot of optometrists, even those he is schooling, do not believe in heterophoria (hidden strabismus), they think its psychological often and that it is really difficult to get proper care for it. He mentioned the best center in the USA being in New York, I think some people already posted a link to health thread.
Ive been given new exercises, which can now be done without a computer and are composed of a translucent board with images I try to connect by converging and diverging. I must say that the divergence, which is my problem, is really difficult, takes forever to fuse the images and then theyre not sharp, sharpness kicks in after another 10 seconds, if anything moves in the field, its lost again. This would explain how dithering/flicker/movement is giving me trouble on the displays. Even trying it with the board properly (no display involved) I soon got the very familiar stabbing pain in the temples and all over the head. I gave it to a person who has no issues with displays and he could connect all of the images effortlessly in an instant.
I really recommend, if you can, trying to find proper care, as it might be what we all have in common. Id love to beat the marketing and display manufacturers, but now even software employing weird rendering, I dont know how, as whenever I win, they come with more, so Id rather build resitance instead. Hopefully that will happen.
martin Blue filter amblyopia treatment protocol for strabismic amblyopia: a prospective comparative study of 50 cases.

Abstract
PURPOSE:
Previous studies of monochromatic visual evoked potentials confirm the strong suppression of (the cortical representation of) paracentral retinal areas of functionally amblyopic eyes, by a flat response to a blue stimulus. A clinical trial stimulating these areas with blue light was encouraging, and justified a prospective comparison of this treatment with conventional classic treatment.
SUBJECTS AND METHODS:
In 50 strabismic children with amblyopia, the blue filter treatment protocol (flash stimulation with, and the wearing of, a blue filter during occlusion of the better eye for one hour daily) was compared with the classical treatment (full time total occlusion by patch) in a prospective matched and randomized study. Patients 3 to 7 years old without previous treatment and a visual acuity up to 0.3 were admitted to the study. Visual acuity and fixation behavior were used as the parameters of comparison. Visual Evoked Potentials by monochromatic flashes were also studied. Results of treatment were compared after 6 months.
RESULTS:
The visual acuity outcome for the blue filter treatment was "statistically significantly" better (p=0.005). The greatest improvement was seen in the subgroup of children with eccentric fixation (p=0.01). Fixation behavior also showed a better outcome from the blue filter treatment (p=0.05) favoring especially children between 3 and 5 years. In children of this age with a visual acuity better than 0.1 we found a very "statistically significant" difference between the two treatments (p=0.004). In children 3 to 5 years old with poorer visual acuity we also found a "statistically significant" difference in the two treatments (p=0.04). The interocular difference of amplitude on the Visual Evoked Potentials also demonstrated more improvement in children treated with the blue filter. This treatment improved especially the cortical response to blue flash stimulation, correlating to paracentral retinal areas.
CONCLUSIONS:
The blue filter treatment protocol provided better results for treating amblyopia than the conventional classic occlusion treatment method. We propose that stimulation of these paracentral retinal areas triggers a better disinhibition of a functionally amblyopic eye.

martin He mentioned the best center in the USA being in New York, I think some people already posted a link to health thread.
Visited the center today. Not sure if it's the same one, if you could get a specific place, I'd greatly appreciate it. I would love to see them.
I was told I have definite eye teaming and focusing issues and very bad depth perception and peripheral vision and suggested vision therapy. He couldn't term a specific diagnosis, but that coverence insufficiency is the closest one.
The vision therapy out of pocket will cost a several thousand USD. I am still trying to see if my insurance will pay for some of it. Out of pocket I'm hesitant to pay for it in total unless I knew it'd fix the issue. But, I don't think there's any harm other then cost and time.
Using my new LG G7 gives me these strange muscle twitches and noise sensitivity. Makes me think it's neurological or nerveous system related. The optometrist told me he thinks my nerveos system is very sensitive based on pupil dilation. He said different colors of light have a great affect on the nerveous system and showed how my muscle strength actually weakened when these light colors came on. I wonder if this phone is emitting some color of light that I'm sensitive to.
He also said my eyes were very slow to focus, something you also seem to take a long time with (mine was several seconds, but not quite 10).
I'm considering trying a different behavioral optometrist to see if they come to the same conclusion that VT is helpful.
Glad to hear about your updates though and love the progress. I really hope this fixes your problem. Please keep them up!!

ryans Amazing to hear that you have some sort of diagnosis and that it fits with the general theory. Really sad to hear how much that costs. Maybe it would pay off for you to take a trip to europe and get the care here, although I dont know how possible it is. When my therapy is finished, including two sets of glasses, It wont cost me more than 600 dollars in total over the 6 months. The prices in usa are outrageous.
ryans Maybe hold off on any expensive therapies until you can evaluate the efficacy. I have done VT before, and I do maintenance exercises at home twice a week which don't cost me anything. Of course it helps that I've been through the training before and I know how to do the exercises. You can always try strengthening your convergence with simple pencil pushups.
These exercises will only help for the issue that your eyes eventually get tired after a long session of computer use, or if you're doing a lot of intense work like in Excel or reading a bunch of email all day.
However, it won't help for the issue where your eyes/brain instantly ache upon looking at the display within seconds/minutes. This happens to me on LED-backlit monitors, and I have not found a solution yet unfortunately. Avoidance is the only recommendation I have in that case. Here's hoping that my Dell U2410 lives a long life!

MagnuM Thats incorrect. You train your nervous system also, therefore it can help with a nervous system response over time. Nerves dont grow like muscles do, but there are adjustments and changes too.
I have an exercise with transparent card, where I see clearly how my vergence works (or doesnt) with accomodation. Its simple and cheap, but you cannot achieve this with pencil pushups.
My optometrist advised me to use a new iphone I bought (iphone 7) to supplement my training in a way that I have to find a line of when the pain gets too much, stop there and repeat when Im fresh again.
It seems the new training Im doing kicked my system into adjusting. Two weeks ago I had a migraine from the phone, then nausea within minutes, then sickness. Now I use it all day and except for a tightness and pressure in head when I look into it too long, its ok. Even played a game on it for hour without the glasses and had slight discomfort at the end of the session.
Also the recovery my body needs has changed, as in I can use it for texting, reading web and so on (even without my glasses now), and if it starts being uncomfortable, I stop and within few minutes to half hour Im ok again, as opposed to the past, when exposure of 15 minutes could result in a days migraine.
I hope this keeps improving with advances in the training to the point when Im part of the 95% who have no issues whatsoever.
I have also changed the background to greyer colors, and set nighshift on permanently at about 35%.
I dont want to get ahead of myself or get my hopes up too much, however if this keeps improving like that, I might be symptom free by the end of the training. I dont dare to use a modern computer yet, but the phone is a welcome improvement.

tfouto Please read back in this thread, the progress is written there. Exercises for convergence excess and accomodation insufficiency. I bought the phone because I needed it, but was afraid it might interfere with my training (it does when I overuse it, tires the eyes so much I cant get results in training after), however he advised me not to be afraid and find a line where I stop and start next day, or later. Couple monhts ago, before the training, I couldnt use it for more than 10-15 minutes and when I did, I had a raging migraine for the rest of the day.
This by no way means there isnt something different with new display tech. My old iphone 4s still is very comfortable to use for hours.
Yes with prism glasses but also now without them. Im still advised to use it with glasses though. It also helped to start one eye at a time only, before implementing binocular vision. So for couple days when I was using the phone I always covered one of my eyes (and was switching them every few minutes).
Came from the doctor. My sight is perfect. Except for the small insuficient convergence. He told me that there was nothing i could do. I asked him if there were eye convergence therapy i could do, he said that it would do anything. But i said i'd like to try, and he gave me a contact. So maybe i would try.
I think there is something about convergence. There's just to many people here who have convergence issues. That seems to much to be just a concidence. He's there anyone here who knows from eye exams, that dont have any convergence isuficienct?
