I used to use f.lux, but after I got my latest MacBook air, I started having severe eye fatigue. It turns out the MBA screen has a lot of flicker, especially when scrolling. If the screen is dimmed and f.lux is on, the flicker is more pronounced. Counterintuitively, when I turned off f.lux and cranked up the brightness, my eyes felt better. I felt f.lux had no impact on my sleep cycles or intermittent insomnia.
This is more of an issue with the MBA but just wanted to let people know in case they were having similar eye issues.
- tptacek 16y agoWeird; I got an Air a few weeks ago and haven't noticed that problem at all.
- rdouble 16y agoI didn't notice it, either. But, if I do a flicker test it's definitely there.
- cromulent 16y agoI experienced painful eye fatigue after upgrading to the LED-backlit MBP. I got some quite expensive eye testing done, only to find my eyes were in good shape. My understanding of the problem is that the LED dimming is done using rapid power cycles (you can't really dim a LED). Some people are highly sensitive to the cycles, I guess I am one of them. I found that 6 squares below full brightness is OK for me, but I still get eye pain sometimes. I'm now going to try changing the color profile.
