Production Description

Sunglasses can block uncomfortable strong light and protect eyes from ultraviolet rays. All this is due to metal powder filtration devices, which can “select” light when it enters. Colored glasses can selectively absorb part of the wavelength band of sunlight because they use very fine metal powders (iron, copper, nickel, etc.). In fact, when light hits the lens, the light is reduced based on the so-called “destructive interference” process.

In other words, when some wavelengths of light (here refers to ultraviolet A, ultraviolet B, and sometimes infrared) pass through the lens, they will cancel each other on the inside of the lens, that is, in the direction towards the eyes. The overlapping of light waves is not accidental: the combination of the peaks of a wave and the troughs of its adjacent waves leads to mutual cancellation. The phenomenon of destructive interference depends on the refractive index of the lens (that is, the degree of deviation when light passes through different substances from the air) and on the thickness of the lens. Generally speaking, the thickness of the lens changes little, while the refractive index of the lens varies according to the difference of chemical composition. And sunglasses should not be in direct contact with the sun.
