If looking too long at your screen is tiresome for your eyes and you think it’s linked to its brightness then you can lower it this way :

In order to know what’s the output device, first type :

xrandr --current --verbose

I get the following :
Screen 0: minimum 320 x 200, current 1280 x 1024, maximum 8192 x 8192
DVI-0 connected 1280×1024+0+0 (normal left inverted right x axis y axis) 380mm x 305mm

And further down :
Brightness: 1

Test what brightness you consider best for your eyes :

xrandr --output DVI-0 --brightness 0.88

When you are ready, you can add the line to your ~/.xinitrc. In doing so the right brightness will be loaded with your startx and you won’t have to repeat the operation each time.
