The principle of computer goggles

Because computer radiation comes from electromagnetic waves, these waves have a certain wavelength and amplitude, and the anti-radiation film is based on the wave of light and interference phenomena. If two waves with the same amplitude and wavelength are superimposed, then the amplitude of the wave is increased; if the two waves have the same origin, the wave lengths are different, and if the two waves are superimposed, they cancel each other out. The anti-radiation film uses this principle to coat the surface of the lens with multiple anti-radiation films, so that the electromagnetic waves of different wavelengths generated on the front and back surfaces of the film interfere with each other, thereby canceling the radiation, achieving the effect of anti-radiation and reducing radiation.
