Eyesight killer

computer

The computer screen is made up of small fluorescent dots, which are flashing. If we want to see clearly, we need our eyes to adjust constantly. We can't feel it ourselves, but it's true, and our eyes are easy to get tired if they want to adapt to it. When typing, the eyes should constantly change between the manuscript, screen and keyboard, and the focal length and distance of the eyes should be constantly adjusted, which will also make the eyes feel tired.

PSP, mobile phone

Even on rickety buses, crowded subways and even elevators, hipsters never forget to play with PSP, iPad or MP4, play games and watch movies. In addition, they are used to staring at the mobile phone and pressing short messages, and staring at the narrow screen for a long time, which makes people feel tired easily.
