AGI You can check next time if the True Tone on Iphone XS was enabled. True tone can make the display much warmer...

tfouto I do not recall. I think some cheap tempered glass...
Thanks on the True Tone. I will check if it has an effect. I wish I could rent an XS for a week at a decent price and check it out seriously. Is True Tone the only difference to the X that you know of? What about the flickering? I heard it was terrible for the X...is it at least nominally better now?
Please remember the topic of the thread. -> Discussions about the XS in the XS thread

Just to share my experience so far. I am starting to hesitate that some relaxation exercise will "cure" the eye strain issue for me.
I am training with Alexander Technique and Feldenkrais for the last 3 years, i may even become a teacher in one if these techniques sometime in the near future, just to demonstrate my level of involvement. It all started as a way to help me with back pain. I am an chartered accountant by profession and long sitting hours had an impact on my back.
In the above techniques we work a lot with the releasing extra tension in the eyes, in the jaw as well the neck. The techniques had such a profound effect on me that even my issue with chronic blocked sinuses have started to feel a lot better without medication. My neck, jaw and eyes are way more "relaxed" or released than 3 years ago. My sleep quality is very good, no teeth clenching or anything like that.
Actually I am 40 and in combination with jogging (3 days per week 30 min per session), i am in the best bodily state ever. I do not follow a special diet though, i am just careful not to eat junk.
However the strain issue, while there is some improvement, is still there. I can actually feel my eyes relaxed and very easy to move but when i sit in front of a newer laptop my eyes become tense and i get an intense headache and neck cramps.
Peter I think the key you said is "newer" laptop. Are there any known-good laptops you can use? If there is, I doubt the problem is you not being relaxed enough, as you would be assuming the same bodily posture on a different laptop and not having the same reaction.
Also, what if you hook up a newer laptop that gives you problems on an external computer monitor that normally you have no trouble with. Does the problem still occur?
Currently i use Inspiron 15 3000 win 10. Its a company pc. I have it for a year and everything seemed fine with some adjustments to the dell color settings and crizal glasses. Some time in the last 2 months some updates were installed and the laptop, although not unusable, it started causing me eye strain & headaches after an hour or so of use. IT in my company told me they do not understand why since display / graphics drivers were not updated.
Currently the only the way to work with the dell without any issue is to connect it to my trusted LG Flatron W1946.
Sorry for a bit offtopic, but i'm trying to finish my 'Lifestyle/Led' survey, but now there are only 16 answers.
I would be very appreciate if you will take participation in it (it's short, will take only 5 minutes), otherwise it would be impossible to publish any statistically correct results. Thanks.

I did one.
I also made short description of my story in neighbor thread: https://ledstrain.org/d/514-blue-light-photophobia-eyestrain-muscle-spasms-pain-twitching/54
Maybe it would be worth for somebody
In a post above I mentioned my story in the neighbor thread. The main point of it is that our problems could be linked with restricted blood flow to brain and eyes. It could be caused by overstressed/overloaded neck muscles.
Recently I've found an article that says that sitting in a wrong position (and work in front of computer usually implies such position) could cause neck muscles restructurisation. Such daily position triggers permanent tension in neck muscles and with time this new muscle scheme becomes default even for daily life. But with this new muscle scheme man get a restricted blood flow to head and muscle.
Article in Russian with some neck exercises (with restrictions) could be found here: https://lifehacker.ru/napryazhenie-v-shee/

Here is the article abstract part translation by deepl dot com:
"Working at the computer is almost always the wrong back position and an extended head. Lifehacker shows exercises that will help stretch and relax hard neck muscles, preventing pain and other cervical spinal problems.
When you're working on a computer, let alone a laptop, your neck is usually pushed forward.
This causes excessive neck muscle strain, which has to keep the head in a non-physiological position.
When the head comes forward and shoulders are raised, the upper part of the trapezoidal muscle and the occipital muscles are tensed. On the contrary, the clavicular-ociliary muscles stretch and lose their tone.

Over time, muscles get used to being tense all the time, so you can't just relax them.
What's more, collagen fascium fibers build up around your muscles and fix them in the wrong position, so you find it convenient.
Tense neck muscles can cause hyperlordosis of the cervical spine - a condition where the neck is overly stretched forward.
This, in turn, worsens the blood supply, can cause intervertebral hernia, cause nerve pinching and other problems.
To avoid getting sick, warm up your neck muscles regularly while doing the exercises suggested. Some of these can easily be done even at the workplace or in the car, others will need a ball, mat or rubber band. They can be done at home or in the gym.
Contraindications are severe neck pain or cervical spine problems such as hernia, nerve pinching or other conditions. In this case, you need qualified medical help and a physical therapist's recommendation."
KM Hm, I too have jaw problems.
Please count me too in. I considered wearing a mouth guard in the past, but I was a bit concerned about eventual side effects so I never did it in the end. Also, I never associated it with eyestrain, although I noticed correlations with my sinusitis and headaches.
