Using computers and phones can lead to fatigue due to radiation. Many people look for anti-radiation materials such as bracelets, sitting mats, radiation shields .
Engineer Nguyen Huy Bun, a former officer of the Military Technical Academy, said that it is difficult for any materials to prevent radiation from the computer . The radiated area of a computer is usually large, emitting sinusoidally. Therefore, only one pair of eyeglasses does not prevent this wave of radiation.
Moreover, it is very tiring if you do not have eye problems and use glasses, even if it is a light-weight glass, it is recommended to use a screen that prevents radiation to the computer rather than wearing glasses. prevent radiation when sitting in front of a computer. For computer screens, just turn on the screen and emit radiation rays.
The source of the computer's radiation is different from a mobile phone. The signal on the screen is made up of electron beams, when the light is emitted to produce electromagnetic radiation. For flat screen computers, radiation emits about 90cm.
In order to avoid computer radiation, adjust the brightness of the monitor to a certain degree because the greater the brightness of the screen, the stronger the electromagnetic radiation. But it is also not advisable to adjust the screen too dark to cause nearsightedness and fatigue. Plant or leave the narcissus pots or cactus pots next to the computer , as daffodils work to "absorb" radiation. It is worth noting that the older the computer, the greater the radiation.
However, the actual radiation of a computer is usually lower than the maximum allowed. The screen should be placed 50 to 60cm away from the eye and the center of the screen should be set lower than the eye level from 10 to 20cm. If the screen is lower or higher than this position, it will make you feel tired of the neck and shoulder.
