@ensete Hello, you seem more experienced than most of the other users, and I think you have been dealing with these issues longer than most of us as well. You've also seen many neurologists and other types of Doctors.
My eye strain popped up out of nowhere like 2 months ago. There was no change of hardware like my monitor or any lifestyle changes that could've brought it on. I'm healthy. At first I thought it was an eye infection because I've never had eye problems before. I went to a minute clinic, then I saw an optometrist, and then an ophthalmologist the other day. They didn't help and I almost got in a yelling match with the latter because he tried to tell me it was due to stress, and that I was trying to get out of work. My vision is 20/20 with no eye problems that they can detect. Generally, if I don't push the pain too far, then it heals overnight and I feel somewhat better the next day. However, I recently started my computer job that I signed a contract for 4 months ago before all this eye pain started haha. Not a fun situation to be in. Also, my Galaxy S8 is pretty much the only screen that doesn't give me eye strain. At the moment, I suspect it might have something to do with the tempered glass screen protector on it. That is the only difference I can think of right now between my phone screen and other screens.
I believe that something changed in my brain for it to start reacting this way. I believe there is something wrong with the way my brain is processing the light from the screens. I hope that this does not get worse.
Haha you seem like you have more wisdom and experience than most on here so what do you think? Do you think my brain has just malfunctioned in a neurological way?
Neurological Malfunction
Your S8 uses an OLED display, I am guessing everything else that causes you problems is LCD.
Some of my screen problems are linked to food. I am fine today, but if I were to eat something containing cooking oil I would not be able to use my monitors without pain for about 5 days. Unfortunately, eating cooking oil causes me no other problems, I only discovered it was the cause of my worsening screen problems by dumb luck. My problem with cooking oil started suddenly, I was fine ok day and in pain the next. Funnily enough, when it started I could use my OLED Samsung S3 mini without pain, it was only LCDs that gave me pain.
Its a long shot, but try eating nothing but plain pasta for a few days and see if you get better. If you do, you can start looking for what your problems foods are. If it doesn't get better then you'll know its not a food thing - or its the pasta!
Hahaha pasta. Are you 100% sure that cooking oil is your cause? I might try that. So when you consume cooking oil you get eye strain from some screens?
Its not my only cause, I can struggle with some screens regardless. But if I were to eat cooking oil, the lcd screen I am using fine now becomes unusable. Similar thing happens if I eat anything with curcumin, or silicon dioxide added (stops salt clumping together, also used in pills). I don't know why, but its been happening for about 4 years now. I have a lot of food intolerances and mild allergies, with new ones appearing fairly regularly. Whilst I don't get a rash or any other symptoms from cooking oil, I assume I am slightly allergic to it, and its getting into my brain and causing some inflammation because of that allergy. Every so often a new food trigger appears.
The first food trigger to affect my tolerance of screens was sunflower oil. I ate a lot of crisps (lots of sunflower oil) one day and was in much more pain the next day. Stopped eating crisps, got a lot better, soon figured it out was the sunflower oil. Since then its slowly expanded to be all cooking oils, and the other things I mentioned.
I haven't found a dietary link, not discounting Seagull's experience, but it's not representative.

The best think would be a elimination diet for 3 to 4 weeks. Starting just with rice and chicken, and broth. Then adding some vegetables, etc.
There lot of info on google on Elimination Diets.
Anyone noticed any improvement from supplementing with a good B complex?

K-Moss I used for some months eye drops containing vitamin B-12 and it did help especially at the start. It relieved symptoms but did not eliminate the problem.

Tommy98 It is called Sancoba Ophthalmic Solution 0.02% : 5ml x 10.
Description: This preparation of vitamin B12 improves muscle function related to eye focusing. It is usually used to treat eyestrain.
Active Ingredients: Cyanocobalamin
I do not want to create too many expectations. It helped, but it does not cure the issue at the origin.
- Edited
Cyanocobalamin is trash. Methylcobalamin is much better.
Edit: That is, if you want a form that can be absorbed and used by your entire body. Cyano needs multiple steps of conversion in the liver that Methyl does not. It is possible that Cyano in eyedrops functions differently when dropped into the eye so I shouldn't dismiss it outright, but I am skeptical.
Interestingly had labs done and am highly b12 deficient
Tommy98 Please check here - heteroforie.webnode.cz
If the optometrist did not find anything, then that unfortunately doesnt mean its still not heterophoria. You can try the home test and maybe find more specialists to try.
It may be stress, but in a different way than you think now - long time under pressure or sudden stress can make heterophoria manifest, as the strain is already too much and under bigger load your body may just give up and let the eyes "slide".
Also a lot of people here are looking for neurological solution - heterophoria IS a neurological issue as well. Its a combination of badly set eye muscles combined with how the visual center in the brain processes stimuli.
