Your post makes sense. What doesn't make sense to me, and drove me down this rabbit hole, is that I do the same things with the X that I used to do with the 3GS, 4, 6, 7+ and 8+. Never had a single problem. > Stop trying to read a phone screen (or look at anything on a phone close up) in a dark room. That's it. Don't do that. It's a thing that makes your eyes and head sore. It's really well documented. True, true. But it doesn't mean that if you sore eyes it's always because of that. Do you ever have the feeling of wanting to know what causes something. Not to prove something, not for any other reason other than figure out why and how. I am in that rabbit hole. I am very happy with the 8+ and have no eye problems at all. But I have to known what is it in X that causes my eyes to go sore.

The simplest answer is that you're starting to have the very slightest amount of age-related focus degradation, that it's only manifesting when the room is very dark, and that it aligned with the new phones by coincidence. That said, older phones had a higher minimum brightness and more mixed-in blue light. Your pupils will contract more when looking at a brighter, bluer screen and smaller pupils focus more easily. Also, being able to see the black part of the screen can make it easier to focus because you can see how far away it is. Normal ergonomic issues like this are probably the cause. Can you get hold of an older model phone and relax with it for a few weeks to check whether the problems are really with the new devices?

  Hmm, it may be what you say. Makes sense. What I have done now is covered the notch with a tape and the strain is gone. Maybe it is that I got used to it as you suggest. At some point I will remove the tape and see if the strain comes back or not.
