Can polarized sunglasses help reduce harmful effects of a computer?
In the previous article, we discussed “Are polarized sunglasses good for night driving?”. In this article, let’s talk about “Can polarized sunglasses help reduce harmful effects of a computer?”.
Nowadays, modern products such as computers and mobile phones are closely related to our lives. However, the radiation generated by the computer is harmful to the human body. So, for the prevention of computer radiation, is it useful to wear polarized sunglasses?
Polarized Sunglasses And UV Protection
In life, too many light sources can produce harmful light, especially sunlight. The rays emitted from the sun are visible rays, infrared rays, ultraviolet rays, etc. Among them, ultraviolet rays cause the most damage to the skin and eyes of the human body. Ultraviolet rays are divided into three types, UVA, UVB, and UVC. UVB has a serious effect on vision. Most corners of the eyes will absorb this UVB light, so this light source must be blocked. Because polarized sunglasses have the function of polarizing light, they can block harmful light without affecting the transmission of visible light, and can truly protect the eyes.(https://www.koalaeye.com/blogs/our-stories)
Polarized Sunglasses And Anti-Computer Radiation
The hidden dangers of computers to human health, from the perspective of radiation types, mainly include electromagnetic radiation (various electromagnetic rays and electromagnetic waves, etc.), sound (noise), light (ultraviolet, infrared radiation, visible light, etc.) And other kinds of radiation 'pollution' generated and emitted by the computer during work. Computer radiation is X-rays, while solar radiation is mainly ultraviolet radiation. The two types are different, and the defense equipment is certainly different. Therefore, polarized sunglasses can filter out ultraviolet rays, but the effect of preventing computer radiation is limited.
People who use computers for a long time can use computer radiation protection glasses. In the processing of computerized anti-radiation glasses, a compound medium is added to the manufacturing material, and then the anti-radiation film is plated on the lens, which can play a certain filtering role for computer radiation. The computer's radiation comes from electromagnetic waves. These waves have certain wavelengths and amplitudes. Compound media and anti-radiation films use this principle to make electromagnetic waves of different wavelengths generated on the front and back surfaces of the lens interfere with each other, thereby canceling part of the radiation. The lenses of computer anti-radiation glasses are made of special glass that can reflect or absorb radiation but can transmit a certain amount of visible light. The lens is plated with bright chromium, nickel, mercury, or silver metal film, which can reflect radiation. The blue lens absorbs infrared rays, the yellow and green lens absorbs both ultraviolet and infrared rays, and the colorless leaded lens absorbs X-rays and γ-rays.
