[Maq.H]

Ever become aware of how people texting at nighttime have that creepy blue glow? Or awaken ready to note down the subsequent great thought, and get blinded by your PC screen? Throughout the day, PC display seems fine—they're planned to appear similar to the sun. But, at 9PM, 10PM, or 3AM, you most likely shouldn't be looking at the sun.

Next time when you work on your computer, the light is not the same. During the day, you're bathed in warm sunlight while in the evening and night, you are enlightened by the cold light of lower bulb or halogen.

The brightness and colors that you see on your screen so disturbed after it found the time and the light source used. The night, for example, your screen falls too bright, which can hurt the eyes and prevent you from sleeping well then.
