My friend PC was too bright it started to affect my eye, I typed this using an eye. Since my laptop didn't give options to reduce it's brightness(Still can't figure out why) i had to do some researches which landed me to this third party app i'll be sharing, it actually works and it's light weight. It doesn't even need to be installed. All you have to do is download and open.

             Once opened, You'd see a "P" icon on your taskbar, left click on it to adjust your screen's brightness.
