Photo attached. Top shows me reading on my couch with settings appropriate to the room light. It's very comfortable and I can read like that for hours.

Below is the same room light, but reading with back on bright white and full light. The room only appears totally black because the photo can't capture the bright light and regular room light at the same time. Reading like this really does fry my eyes. But I never read like this.

Outside in bright light, the bottom settings would be fine. Although I prefer shade to full sunlight.

So I wonder, of those of you who say that reading on a phone or tablet hurts your eyes...are you trying the top example where you have a dark background with low contrast color for text and the light level set to room ambient level?
