if you have any of the newer iPhones and ok with it then you should be good
I thought the same when I bought the 11” M4, but looks like this is the first screen which ever caused eye strain to me. 🙁 I used throughout the years several screens with LCD, mini-LED, OLED (only on iPhones & Watch till I bought the iPad last week), and none of them caused eye burn within 5-10 mins like the iPad does. I work on a 16” MBP with mini-LED, and I can look on the screen all day (and I do, since I’m an iOS developer).
Although I have to say, maybe my eyes got adapted, or the OLED had some run-in period, but I can stare at the iPad for 20-30 mins without eye strain after about a week of usage 🤷♂️ I’m glad I kept my M1 Pro, so I can still test the new one within the return period, but I might have to return it.
(By the way, it’s the best iPad I have ever touched except the screen, which is unfortunate: lighter, more stiff than my M1, snappier performance, etc)
