I too am getting sick of backlight displays. I work all day in a dim office and if it wasn't for redshift on linux I'd go crazy. I change the color temperature to 4500 K and reduce the backlight to 65% of maximum brightness. You will think that 65% is too little, and maybe it is on your display, but try it for 30 minutes then try 100% again.

    redshift -l geoclue2 -t 4500 3000 -b 0.65
