I use Redshift under Linux to do the same thing.
HA; Beat me to it while I was looking; I was unfamiliar with it until just now.
Here is a REDSHIFT endorsement>>>>> Great name by the way! >>>>>>>>>>

One of the first few things to do after installing Linux Mint 18 is to install Redshift. Not only Linux Mint, in fact, Redshift has become an integrated part of my computing life.
This little app changes the screen temperature according to the time of the day. At night, it reduces the temperature so that you see a pale yellow screen which is easier on eyes at night. Similar feature has been introduced in iOS recently as Nightshift but Linux and Android had it available for a long time.
There is also an alternative application f.lux that provides more configuration options in the GUI. Redshift, on the other hand, is install and forget kind of program. Install it and run it. No configuration required. I have written about using f.lux to get Nightshift feature in Linux in a separate article, in case you want to have a look at that.

Installing Redshift in Linux Mint is very easy. You can search for Redshift in Software Manager to install it.
thnaks for headsup- looks promising- I’ve had to shift to wearing ‘computer glasses’ which basically do the same hting- the screen however is a constant pale yellow- day and night- it has made a difference- my eyes used to sting, water, and feltl ike pressure building up- until i got the glasses- they’ve made a big difference really- no more stinging eyes-
