Eyestrain with boox go 10.3

I have boox go 10.3. I had the note air 1. With the first one, my eyes start to irritate after less than an hour of reading. On the other hand, with the note air I could read for hours and hours without feeling any eye discomfort. Will it have to do with the Carta 1200 screen? I don't know. Maybe I'm the only one or maybe it's happening to someone else.
