Why are polarized sunglasses more comfortable and softer than ordinary sunglasses


The polarizing function of sunglasses can block the glare in the sun, which can protect the eyes from ultraviolet rays. All this is due to the metal powder filter installation, which can comb the messy light into the correct light when the light enters, so that the light entering the eye will become softer. Recommended reading: How to tell if it is true polarized glasses Polarized sunglasses can selectively absorb the local wavelengths that make up the sun's rays 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 intervention' process. That is to say, when certain wavelengths of light (here referred to as ultraviolet a, ultraviolet b, and sometimes infrared) pass through the lens, they will cancel each other out on the inside of the lens, that is, toward the eye. The mutual stacking of light waves is not an occasional phenomenon: the crests of a wave merge with the troughs of the adjacent waves, and they cancel each other out. The phenomenon of destructive intervention depends on the refractive index of the lens (that is, the level of deviation when light passes through different substances in the air), as well as the thickness of the lens. Generally speaking, the thickness of the lens does not change much, and the refractive index of the lens varies according to the difference in chemical composition. Polarized sunglasses provide another mechanism for eye protection. The reflected light from the asphalt road is quite special polarized light. The difference between this reflected light and the light directly from the sun or any artificial light source lies in the order. Polarized light is composed of waves that vibrate in one direction, while ordinary light is composed of non-directional vibrating waves. This is like a group of people walking in disorder and a group of soldiers marching at a uniform pace, forming a clear contrast. Generally speaking, reflected light is an ordered light. Polarized lenses are particularly effective in blocking this light because of their filtering properties. This kind of lens only allows polarized waves that vibrate in a certain direction to pass through, just like 'combing' light. Regarding the road reflection problem, the use of polarized sunglasses can reduce the transmission of light because it does not let light waves that vibrate parallel to the road pass. In fact, the long molecules of the filter layer are directed to the degree direction and can absorb highly polarized light. In this way, most of the reflected light is eliminated, and the overall illuminance of the surrounding polarized sunglasses environment is not reduced. Finally, the lenses of polarized sunglasses can darken after the sun's rays hit. When the lighting diminished, it became bright again. This is possible because the silver halide crystals are working. Under normal conditions, it can make the lens maintain perfect transparency. Under the sunlight, the silver in the crystal separates, and the free silver forms a small collection inside the lens. These small silver aggregates are criss-crossed irregular blocks. They cannot transmit light, but can only absorb light. As a result, the lens darkens. In the light and dark conditions, the crystal is reconstituted, and the lens is restored to its bright state.
