Enabling night light mode in Windows 11

Do I need a software or night light glasses?

Using this mode will save your eyesight when your working or gaming at night stopping any screen glare and it's free. 

You don't need a Software to do this and shouldn't need to waste on money just for the same thing. Using Night light Software could contain unknown malware which your malware scans can't detect.

If you feel you need a UV glasses for gaming, speak with your Opticians.
