What is a polarized sunglasses?
What is the difference between and BianSeJing?
That is more suitable for driving?
Polarization: the definition of a polarized light can be divided into three kinds, namely linear polarized light, ellipse polarized light and circular polarized light.
General so-called polarization refers to the linear polarized light, also called plane polarized light.
The vibration of the waves along the direction of a specific fixed, in the space of the transmission line as the sine curve, in the vertical direction the plane for a straight line.
Linear polarization direction and the direction of propagation of vibration plane is called the vibration plane, and the vertical direction of vibration and contains surface in the direction of propagation is called polarization plane.
Take the natural light through the polarizer, linear polarized light can be obtained, is often used in the study of crystal optics.
The principle of polarized lens: polaroid is made according to the principle of polarization of the light, namely, the vibration of the light plane and the polarization axis parallel, polarized light filter can make polarized light through (
As the principle of shutters)
Light is subdivided into light into the eye, the surrounding scenery looks clear and not dazzling.
Wear polarized sunglasses before and after the contrast simulation wear polarized sunglasses have what effect?
Adjust the Angle of polarizer, the surface of the water, glass, flowers and plants, such as water vapour partial seismic reflected light can be cut off, the normal light can partly through, thus enhanced contrast, reflective, enhance the effect of landscape color, reduce atmospheric fog phenomenon, let you see the world clearly, also you a colorful world, more blue sky, more beautiful nature.
When polarized sunglasses are suitable for wear?
Wear polarized sunglasses there would be no distortion of scenery and the feeling of vertigo, resin polarized lens has light, not easy broken, the advantages of wearing a relaxed, comfortable.
Suitable for fishing, driving, sports, sailing, skiing, hunting, etc.
What is the difference between polarized sunglasses and BianSeJing?
BianSeJing is colorless indoors, as ordinary glasses used;
In outdoor uv discoloration, used as sunglasses, a dual lens, but for driving, polarizer than BianSeJing applies.
