To Protect Eyes while Using Laptop? By Set Up Window Colour

Everybody understand the harmful effect of using too much computer or laptop. Hence, I'm not going to elaborate about the side effect of using computer. However, almost every individual requires to use computer everyday. Students used laptop to do their assignments, workers used it for their works and communication. It is quite hard to avoid us from dealing with computer. But, atleast we can minimize harmful level to our eyes.
One of the way is to adjust the brightness of the computer screen/window to protect our eyes.

Besides, you may set up screen/window colour.
For the sake of your eyesight, do the configuration to your computer. It is quite useful and you will feel more comfortable to your eyes.
