Hi, I bought a Macbook pro 13" retina display (early 2015) in february 2017. Previously I have used windows desktop with LG 15" monitor and another windows dell laptop with 15.6" screen. This is my first mac. Since I use the laptop mostly for reading, I find myself getting eye strain after using this laptop. The laptop is flashing on my eyes. I use brightness level at 4. If I use 3 as brightness level, it is very dull and cause strain. 4 is very bright and cause strain. I tried brightness in between 3 and 4 and that also causes strain. Since I use for reading, I keep target white point at 6000. I use native resolution. I always place tube light behind the laptop screen. (Or can I say I keep laptop screen before the tube light so that there is no glare. Is there anything I can do apart from these three things so that I can read without strain? Am I getting strain because screen is very small at 13"? If you have any link or webpage suggesting where the light should be placed compared to the computer, kindly tell. Will color sync utility help? What are other options to adjust monitor?
