Although I used to like Amoled screens, IPS screens have been way much easier on my eyes when looking at my phone for prolonged periods of time.
That's interesting, I've always though the other way around since the AMOLED brightness can get dimmer.
I have a screen filter app for viewing in extra dark places. It makes the screen appear dimmer than the backlight can go.Interesting , I never view my device in an environment with the need to dim the display. I've tried view dim in the dark but it hurts my eyes way too much after a little bit of viewing.
