![]() ![]() Well, same results at 1920x1200 as when the MBPr is in the retina display setting (1440x900). So, is there something behind the white background and then the sharp text that is causing the tunnel vision feeling? #Mac app for eye strain full#When I move my focus to a full color photo wallpaper, the eyes tend to relax a little bit. One sensation I feel like I am recognizing is that if I am focused on typing black text on a white background, I get tunnel vision to that portion of the screen. Last night I returned to my (early 2011) 17" MBP running at 1920x1200 and had no discomfort. But I'm trying any idea at this point to see where the issue is. ![]() Our eyes don't need to struggle to understand anything its seeing but I am wondering if its sensory overload in the beginning? A 15.4" screen running at 1920x1200 should be more likely to cause eye strain because everything is so much smaller. I know the logical thing is that our eyes should relax in the retina display because its so sharp. Today I am going to run it in 1920x1200 mode to see if the results are any different. I have been running my MBPr in retina display most of the time. ![]() But they should know I'll pay any price to not get blind ! I am waiting for Apple to give us a problem free screen. I have been folowing this since I got my macbook air 2010. Some are not aware, and will one day suffer consequences, some like us know and feel the problem. Eyes and brains do not like this, and especially if the time "off" is important in comparaison to the time "on". When the led is "on" the light is very bright (even blue which I read is bad as well!?). Part of this time the led is "on", part of this time the led is "off". If your led is activated at 100 hz, the total signal period is 1/100 of a second. This result (in my opinion) to low led frequency and poor modulation. It seems that the "air" has a different screen, or different system to activate the led backlighting, probably to save weight and thickness. ![]()
