A wonderful free utility for night viewing of a computer screen or for those with various eye issues:

Here is a sample of a custom color scheme that I use showing a snippet of PB:

To get the green effect shown above, close the Negative Screen program if you are running it. Then use a plain text editor to open the file "negativescreen.conf" installed in the program's folder and add the following at the end of the file:

Negative Green=win+alt+F12
{ 0.0, -0.3, 0.0, 0.0, 0.0 }
{ 0.0, -0.6, 0.0, 0.0, 0.0 }
{ 0.0, -0.1, 0.0, 0.0, 0.0 }
{ 0.0, 0.0, 0.0, 1.0, 0.0 }
{ 0.0, 1.0, 0.0, 0.0, 1.0 }

Save the file and re-launch the program. Then select the option from the program's icon in the task bar using the right-click option or use the win+alt+F12 key combination.

To make the green text option the default edit the line below in the negativescreen.conf file to read:

Change this...
InitialColorEffect="Smart Inversion"

to this...

InitialColorEffect="Negative Green"

Note that if you use Chrome as your browser you may want to install the Reluminate extension:

https://chrome.google.com/webstore/detail/reluminate/ejfgkpndiembgmnikjbdkbiiobdmcgji

Reluminate is for use with color inversion utilities such as Hacker Vision or Negative Screen. Reluminate will invert the inverted images on most web pages so that pictures on the pages do not look like photo negatives. You may have to refresh the page after activating Reluminate or changing its image inversion settings on particular web pages. Remember to disable Reluminate when you are not using utilities like Hacker Vision or Negative Screen, too.

Try these out. Your eyes will thank you.

I've found this to work well for me: Flux. It takes some getting used to, but it changes the warmth of the screen to match the time of day. I find it makes it easier to use the computer closer to bed. It's free, for Windows, Mac, Linux, and iOS: https://justgetflux.com/ (Although I've not tested it on the Apple platforms)

Also, on Android, I use EasyEyes to do the same. I just enable if I need to use my computer at night: https://play.google.com/store/apps/details?id=com.palmerin.easyeyesfree
