What is Polarized Lens
There are three types of polarized light, namely linear polarized light, elliptical polarized light and circular polarized light. Generally, the so-called polarized light refers to linearly polarized light, also known as plane polarized light.
The vibration of this light wave is fixed along a specific direction, the propagation route in space is a sine curve, and the projection on the plane perpendicular to the propagation direction is a straight line.
Principle: When passing through this polarized filter lens, it is filtered out by the louvered structure of the black crystal, and the remaining useful vertical light enters the eyes, so as to achieve the purpose of blocking the reflected light, and the feeling is comfortable and clear.
Usually the sun shines in all directions. When it hits the object, the light will be re-reflected to form two kinds of light, horizontal and vertical. It consists of 7 layers of flakes.
The polarizing filter layer is made according to the polarization principle of light, and its material is composed of vertical molecules (the principle of blinds), which can filter the dazzling reflected light and scattered light, so that the messy light becomes parallel light and enters the eyes, thereby having The function of eliminating glare can effectively weaken strong light and make the field of vision clearer.
There are too many light sources in life that will produce harmful light, especially sunlight; there are three types of light emitted from sunlight: visible light, infrared light, and ultraviolet light. Polarized sunglasses have the function of polarizing light, so they can block all harmful light without affecting the transmission of visible light, which can truly protect the eyes.
The polarizer is the function of the window-blinds, which blocks the strong light so that people can see the real object more clearly. You can wear polarized lenses in daily life whether it is sailing, outdoor activities, or driving at night.
In summer, when the sun is dazzling and thunderstorms are frequent, remember to put a pair of polarized sunglasses in the car.
Polarized lenses are globally recognized as suitable for driving. Glare occurs when light is partially polarized when emitted from the surface of an object. The inverse effect of glare - enhancing brightness, reducing color saturation; blurring the outline of objects, causing eye fatigue and discomfort.
The polarizer is made according to the principle of polarization of light, and has the special function of effectively eliminating glare, filtering chaotic light, improving the driver's vision and increasing the driving pleasure.
