The damage caused by radiation from mobile phones and computer screens has attracted widespread attention in society. At present, various types of radiation resistant glasses are also emerging in the market, so are radiation resistant glasses really effective? How to distinguish the authenticity of radiation protection glasses? The so-called anti radiation glasses refer to the addition of some anti radiation substances to the materials during the lens production process, and the application of an anti radiation film layer on the surface of the formed lenses to achieve the goal of anti radiation.
Due to the fact that computer radiation comes from electromagnetic waves, etc. These waves have a certain wavelength and amplitude, and the anti radiation film is based on the fluctuation and interference phenomena of light. If two waves with the same amplitude and wavelength are superimposed, the amplitude of the waves will increase; If two waves have the same origin and different wave paths, then if these two waves are superimposed, they cancel each other out. Anti radiation film utilizes this principle by coating multiple layers of anti radiation film on the surface of the lens, causing electromagnetic waves of different wavelengths generated on the front and back surfaces of the film layer to interfere with each other, thereby offsetting radiation and achieving the effect of anti radiation and reducing radiation.
After understanding the working principle of radiation protection glasses, a friend once again asked: How to distinguish the authenticity of radiation protection glasses? Due to the blue anti radiation film coating on the surface of the anti radiation lens, when you pick up the glasses and shake them left and right, some blue colored light shines on the surface, while ordinary glasses do not emit any illuminated light. Take a look at the computer and see if you have any different feelings. When looking at a computer without wearing any radiation resistant glasses, you may feel that the monitor is particularly glaring and slightly bouncing. If you wear radiation resistant glasses, you can clearly feel that your vision is clear and natural.
Finally, for a pair of glasses, the most important part is the lens. Therefore, when placing radiation resistant glasses, do not let the mirror face down. Instead, place the mirror face up or upright. If placed facing down, it will wear out the most important center part of the lens, which will not have the effect of radiation protection.
