II. Sunglass Lenses:
Sunglasses can provent uncomfortable glare, while protecting your eyes from UV rays.
All thanks to metal powder filtration devices that "choose" when it comes in. Colored spectacles selectively absorb part of the wavelength band that makes up the sun's rays because of the use of very fine metal powders (iron, copper, nickel, etc.). In fact, when light shines on the lens, light is diminished based on the so-called "destructive interference" process. That is, when light of certain wavelengths (here UVa, UVB, and sometimes IR) travels through the lens, they will cancel each other out inside the lens, ie toward the eye.
It is not by chance that the formation of light waves overlaps with each other: the wave crests of one wave, together with the wave troughs of the wave near it, result in mutual cancellation.
