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.
