The first measure: When operating the computer, it is best to install a computer-specific color filter on the display to reduce the radiation hazard. Do not place idle metal objects in the room to avoid re-emission of electromagnetic waves. When using a computer, adjust the brightness of the screen. Generally speaking, the greater the screen brightness, the stronger the electromagnetic radiation, and vice versa. However, it should not be adjusted too dark, so as not to affect the effect due to the brightness is too small, and it is easy to cause eye fatigue

The second measure: the placement of the computer is very important. Try not to let the back of the screen face people, because the computer has the strongest radiation on the back, followed by the left and right sides, and the front of the screen has the weakest radiation. The distance between the eyes and the screen should be able to see the characters clearly, but at least 50 cm to 75 cm, so as to reduce the damage of electromagnetic radiation.

The third measure: pay attention to indoor ventilation. Scientific research has confirmed that computer screens can produce a carcinogen called brominated dibenzofuran. Therefore, it is best to install a ventilation fan in the room where the computer is placed. If not, pay special attention to it when surfing the Internet.

The fourth trick: buy new computers as much as possible. Generally, do not use old computers. The radiation of old computers is generally more severe. Under the conditions of the same distance and similar models, it is generally 1-2 times that of new computers.
