One-piece lens sunglasses
CONCHEN NO. 7001# 【UNIQUE DESIGNER-ONE-PIECE SUNGLASSES】One-piece mirrored sunglasses for women men. Integrated mirror lenses restore true colors, eliminate reflected and scattered light, and protect the eyes perfectly. The frame structure is clearly visible without losing the sense of fashion design. The mirror reflects perfect scenery, and the beautiful scenery matches your beautiful face very well. Selfie artifact.
Sunglasses can block uncomfortable strong light and protect eyes from ultraviolet rays. All thanks to metal powder filters, which "select" light as it enters. Tinted glasses can selectively absorb part of the bands 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, it is subtracted based on the so-called "cancellation interference" process. In other words, when certain wavelengths of light (in this case, ultraviolet A, ultraviolet B, and sometimes infrared) pass through the lens, they will cancel each other on the inside of the lens, that is, towards the eye. The overlapping of light waves is not accidental: the combination of the peaks of a wave and the troughs of its adjacent waves results in mutual cancellation. The phenomenon of interference cancellation depends on the refractive index of the lens (i.e. the degree of deviation of light when passing through different substances from the air) and the thickness of the lens. Generally speaking, the thickness of the lens changes little, and the refractive index of the lens varies according to the chemical composition. And sunglasses can't be in direct contact with the sun.
