![]() Thus to select the best value we will need to select the value with lowest blue light and highest green light, but green light should also be reduced for best eye protection and sleep. ![]() ![]() It’s important to know that most softwares reduce also the green light at low values and red light is untouched at all values. The height of the red part of the shows the amount of red light emitted. The height of the green part of the shows the amount of green light emitted. The height of the blue part of the graph shows the amount of blue light emitted. We will just use this measurement as comparission to other values and as how normal displays emmit colors. You see that blue light is even more than all other colors and this is the first reason that this value is bad for your sleep and for your eyes. 6500K – 100%Īt 6500K this is how the color graph looks like. They may do it with different algorithms, but the end result is the same. No matter what anyone tells you all this softwares do the same thing with color temperature. The bellow measurements are the same for all software products. Actually Redshift can go down to 1000K, f.lux to 800K, SunsetScreen to 500K and Iris to 0K, but this is irrelevant. This is perfectly calibrated screen.ġ200K is the lowest value of f.lux, Redshift, Night Shift and Night light. I made a 10 measurements of the display from 6500K to 1200K since this is the format that is universal to all blue blocking softwares and I think is enought.Ħ500K is screen with no color changes at all. Twilight is like the Iris Overlay mode and Night mode is like the Iris Groot color scheme. The Android Twilight and Night mode use different algorithms than Color temperature. This will be helpfull for users of other software products like f.lux, Redshift, SunsetScreen, Night Shift and Night Light. Well in this article I’m going to look at exactly this with measurements. A lot of users asked me what is the best value of Iris for blue light reduction. ![]()
