PuffyCloud you are correct. Feel very fortunate after reading how affected ppl are by the pwm. I may occasionally feel it in the prefrontal cortex area (I'm guessing) behind the upper middle part of my forehead. By flipping through screens swifly.
I am on my s8 now and it's a okay experience the majority of the time except if outside. Also, I will occasionally feel a bit of discomfort in the corner of my eye but I think it's my environment. Something reflecting light in my peripheral vision while I'm staring at the screen. I try make my environment more and more conducive every day to looking at a screen.
And when I type occasionally I can feel the discomfort when new letters appear on the screen. Like muscles in my forehead or on my cheeks. I think this is environment to. This happens much less with the blue light built in filter.
Usually, I can switch positions and these things will be much less apparent. Example, if laying in bed. One side of my face is on the pillow. While the other is exposed to a mostly dark room. My left eye (exposed to the room) will let me know it's not comfortable sometimes. Things in the room still reflecting even with low light. But the right eye is fairly happy.
Any synthetic or petroleum-based material will reflect the light worse (any light maybe =') ) . 100 percent cotton seems to not reflect the blue light as bad. I put this on the walls in my office and am going to try some 100 percent bamboo cotton or traditional cotyon sheets with no microfiber I think to see if the typing in bed is better.
I still haven't gotten my issues down to a science. But being productive by consuming info through screens seems with in reach.
Lastly, I bought goggles to keep reflection from the edge of my eye and it helped a ton. They fogged up but it was a huge relief in terms of me closing in on what makes my eyes happy.
I had prk done in one eye just over a week ago. Thus far it has allowed me not to wear glasses and looking at the screen is so much better. I still wear the goggles sometimes. I hate to look at my 1080p monitor. That thing is junk compared to this device.
Im considering a 5k monitor. Ohh the price tho. But the experience may be worth it. hate saying I'm desperate but I am a bit after looking at the resolution on this phone for longer periods at a time. And the going back to the monitor.
